How to achieve more work through reorganised office communications

  • Why is our current way of working not working? Why do we try but fail to assimilate multiple input channels (phones, emails, meetings, etc) whilst not achieving deep work?
  • From sleep and nutrition to mental resilience/focus and creativity, what are the key considerations for more efficient and happier teams?  
  • How to organise the working day to maximise efficiency, which ultimately positively impacts the bottom line?

Presentation given on 4 October at UCX 2025, Excel, London

Unified communications help us to bring people together and make it easier for us to communicate as a whole and as individuals. However, we are the elephant in the room; we know more about computers than we know about ourselves. So I am going to dive into the Quick Guide to our Operating System and compare us to a PC. It may be simplistic, but I hope it will serve our purpose.

  • There are many makes and models of all sizes in various colours and languages. All are waterproof.
  • Power supply – Gut biome
  • Central Processing Unit – The brain
  • Chipsets – Chemicals/hormones that switch different brain circuits
  • Internal wiring – Axons
  • Memory – Working, short and long term
  • Macros – Habits
  • Feedback loop – The nervous system
  • Firewall – The autonomic nervous system (fight, flight or freeze) and (rest & digest)
  • Back-up & maintenance – Sleep

Nutrition

Professor Tim Spector, King’s College, London

Let’s examine the power supply. Any interruptions will cause a drop in performance. Proper nutrition is essential for supplying our body and brain with the right balance of chemicals to enable us to function. What you eat is your choice, but I recommend a varied diet including plenty of protein, fruits, and vegetables. Incorporate low-sugar fermented foods such as kefir, kimchi, and kombucha, and ensure you include omega 3 rich fatty acids. Foods containing the two essential amino acids, tyrosine (which supports dopamine production for cognitive function, attention, and stress response) and tryptophan (which supports serotonin for mood, sleep, and well-being), will provide the brain with sufficient nutrition for the autonomic nervous system to operate properly.

Tyrosine, an amino acid important for neurotransmitter production, is found in soybeans, beef, lamb, pork, chicken, fish, nuts, eggs, cheese, yoghurt, beans, and whole grains. Tyrosine is a building block for dopamine, epinephrine and norepinephrine, which are vital for alertness, mood, and cognitive function. 

Tryptophan, an amino acid important for neurotransmitter production, is found in chicken, turkey, fish, eggs, cheese, milk, nuts (peanuts, cashews, walnuts), seeds (pumpkin, sesame, sunflower), and soy products (tofu, tempeh), oats, quinoa, and bananas. Tryptophan is crucial for the body’s production of serotonin and melatonin, which regulate mood and sleep. 

A report recently published said that there were now more obese children than malnourished ones. That means that the parents of these children and the environment they are living in are influencing the way they eat. Probably too many ultra-processed foods and fizzy drinks that do not provide good nutrition. We tend to overeat, so eat smaller portions and avoid these ultra-processed foods; aim to fast for at least 12 hours each day. Hydrate with water and be mindful that alcohol can destroy much of the beneficial bacteria in the gut.

Neuromodulators, Neurotransmitters and Hormones

We use neuromodulators and neurotransmitters to activate or deactivate our brain circuits. I am going to concentrate on adrenaline, dopamine, serotonin, and acetylcholine. Hormones such as cortisol and melatonin are crucial in regulating wakefulness and sleep cycles. Proper nutrition ensures a balanced level of these chemicals. Imbalances, whether too low or too high, can lead to mental instability.

  • Adrenaline – A hormone in the sympathetic nervous system, triggering the “fight or flight” response.
  • Noradrenaline – A neurotransmitter, influencing arousal, attention, cognitive function, and emotional response. 
  • Dopamine – A neurotransmitter in the brain’s reward system, contributing to motivation, drive and satisfaction. It also influences movement, memory, learning, mood, and attention. Deficiencies in dopamine levels can cause Parkinson’s disease, and an imbalance can lead to ADHD.
  • Serotonin – A neurotransmitter influencing mood and behaviour. It regulates sleep, appetite, and digestion. Low serotonin levels are linked to depression, anxiety, and other conditions.
  • Acetylcholine – A neurotransmitter regulating heart rate, attention, focus, learning and memory. 
  • Cortisol – A hormone that regulates metabolism, blood pressure, circulation, inflammation, stress response and controls sleep cycles.
  • Melatonin – A hormone regulating the body’s circadian rhythm and promoting sleep.
  • Adenosine – A neurotransmitter that promotes the sleep drive.

What makes something personal to us is memory and the emotional connections formed through this interaction. We rely on working memory for our daily tasks, and these are usually discarded unless they are considered important enough to be stored in short-term memory, then transferred to long-term memory during sleep. This process occurs subconsciously. Having the right level of dopamine available can support working memory.

Habits are an effective way for the brain to operate on autopilot without effort. This means that breaking habits usually requires more effort and time. Addiction is a habit that becomes uncontrolled, driven by an increase in dopamine, a neuromodulator linked to motivation and drive. When a spike in dopamine does not return to its baseline level, it leaves you craving for more, which is then amplified by higher spikes. Everything from gambling, power, alcohol, and drug abuse is connected to this brain circuitry.

Sleep (Doctor Matt Walker, Professor of Neuroscience and Psychology, University of California) is when all of the day’s efforts are stored in our memory, and our body and brain are flushed of harmful debris and then repaired. Rapid eye movement (REM) sleep repairs the brain, while non-REM (deep sleep) repairs the body. If there was only one thing you could do to look after yourself, it would be to get a good night’s sleep. This should be 7–9 hours of quality sleep, and the time you go to bed and wake up should be close to the same time every day (within 30 minutes). You need to align your sleep and waking patterns with your chronotype, which is your natural sleep and wake times, and we all differ in this regard.

The nervous system functions as a feedback loop, with the Vagus nerve being one of the most vital nerves in the body. It has sensory and motor functions connected via axons to major organs and to the brain. It is part of our immune system and serves as the main pathway for delivering serotonin to the brain. Serotonin is a neuromodulator linked to feelings of calm and fulfilment, or rest and digest.

The sympathetic part of our autonomic nervous system acts as our body’s defence mechanism against threats. This is also known as the fight, flight, freeze response. As the name suggests, it operates automatically, preparing the body for action by releasing surges of adrenaline, cortisol and dopamine. Parts of the body that are not needed to respond are shut down. It is only when the signal reaches the frontal cortex that you begin to interpret events and decide what action to take. The parasympathetic nervous system (rest or digest) response produces serotonin and acetylcholine and is calming.

The brain is a prediction machine. Anxiety and stress are part of our instinct to prepare for what might happen next and gather resources to handle it. These responses occur constantly, and in most cases, you don’t notice anything unusual. We have become used to hearing how anxiety and stress have a negative label, with emphasis placed on how it is becoming worse, but for most of us, we experience positive outcomes every day.

I often imagine myself in a coracle without a paddle on a river; sometimes the river is calm, and other times I am rushing through rapids. The water can be deep and threatening or shallow and sparkling. I may encounter obstacles along the way, but given time, I will find a way around them. I have fallen into the water several times but managed to scramble back into the coracle and carry on. Although it can be frightening at times, that body of water has carried and supported me throughout my life. I have been joined by family and friends, and although some have drifted apart, our connection has made us stronger. Outcomes depend on how you approach the many situations you face, and that depends on your mindset.

Stress is Enhancing

Dr Alia Crum, Associate Professor of Psychology at Stanford University

Asking yourself questions gives you useful tools that can be implemented to improve yourself. This is very important because:

  • When we assign performance or intelligence labels to things we excel at, we internalise that sense of self, which boosts our ego. However, if we don’t perform well, we internalise a sense of failure and associate our identity with that diminished performance. 
  • If you attach effort verbs to explain why you are good at something, as well as why you are not, then there is always room for improvement. 

The Anterior Cingulate Cortex (ACC) is the part of the brain that is activated. The Rostral area deals with emotion, and the Dorsal area with cognition.

  • The stress response is mobilising resources to analyse what to focus your attention on.
  • When discussing verbs like effort, persistence, practising, or analysing errors and why you did something incorrectly, going back to the drawing board to put it right is inherent to you. When you start viewing your successes within your failures through the lens of verbs, you’re engaging with something central to who you are. It’s machinery that exists in your brain, nervous system, and body, which you can activate. Focus on verbs, not labels. It is essential to do this when you have performed well in something.
  • If you tell someone they are great or brilliant, you may undermine their future performance when they encounter challenges, because their emotional state will be affected.
  • When you give someone feedback, and it is grounded in effort and persistence in problem-solving, you are providing them with a path to learn from their endeavours.
  • Seek help from others in understanding why your performance was good or, more importantly, not so good. This will consolidate your future efforts.
  • When there is no one to converse with or give you feedback, you can become your own teacher by writing as if to someone else, explaining how to adopt this mindset.

We only stress about things we care about.

  1. Acknowledge that you are stressed 
  2. Welcome that you are stressed 
  3. Utilise the stress response to achieve the thing you care about

Use positive affirmations with verbs – not labels

The Mental Health Continuum

Statistics show that chronic negative anxiety and stress are the most common causes of mental ill health, unless you were born with a mental illness or condition, or have suffered trauma. Here is a diagram of the Mental Health Continuum, illustrating how our lives can become unmanageable.

We are not taught about mental health, and no one wants to admit that they cannot cope. Everyone should have this chart available so they can understand their state of mental health. Every organisation should have this displayed so that people can refer to it or just point when they are feeling low. By normalising the conversation around mental ill-health, the stigma of personnel not coping will diminish, and organisations will be able to provide appropriate help and see their rates of sickness fall.

The Physiological Sigh

If you are feeling overwhelmed or in a state of panic, the quickest way to calm yourself is to use a breathing technique called the Physiological Sigh. This can also improve sleep, lower your heart rate and enhance mood if practised for five minutes a day. This works by utilising the fact that during an exhale, the volume in the diaphragm is constricted, inducing the heart to beat faster, whereas the brain wants it to remain constant, sending a signal to beat slower. By doing the following, your heart rate is reduced:

  • Take a deep inhale for about 4 seconds, then take a short ‘top-off’ inhale to inflate the lungs to their maximum (this removes any carbon dioxide in the lung sacks)
  • Release all the air with a full ‘lungs-to-empty’ exhale, around 8 to 15 seconds
  • Repeat two to three times

As I have mentioned, communications flood us every day, much of it coming from our smartphones, which have become our main companions both socially and at work. It has been reported, we consume 74GB of information a day. 100 years ago, we would have consumed that amount in a lifetime!  We can reach information overload very quickly, which hampers our ability to focus.

The Ultradian Rhythm
Internal clocks govern us; the most familiar is the 24-hour clock or circadian rhythm, but the one that controls our daily routine is the ultradian rhythm. Research from the Sleep Research Laboratory at the University of Chicago revealed that our minds naturally operate in 90-minute waves of high-focus activity. During these periods, your brain enters a state of enhanced cognitive function, where problem-solving abilities and creative thinking reach their peak.

A study published in the Journal of Cognition showed that professionals who aligned their work with these 90-minute cycles reported 40% higher productivity levels compared to those who worked in random time intervals. Even more impressive? These focused blocks resulted in fewer errors and higher-quality outcomes.

By working with your brain’s natural rhythm instead of against it, you’re setting yourself up for success. Think of it as surfing the wave of your peak mental performance – when you catch it just right, everything flows effortlessly!

  • As you start your day and get yourself into a flow of sustained activity and mental focus, your body and brain start burning through a significant amount of oxygen, glucose, and other energetic fuels.
  • Within about an hour and a half, you reach the apex of your productivity, entering what’s known as an “ultradian performance peak.”
  • Meanwhile, the byproducts of all your mental and physical activity— metabolic waste, snippets of data, cellular debris—are building up in your system.
  • After about an hour and a half or two hours, you begin experiencing this accumulation of all this detritus as stress. Your productivity and performance start to decline as your body enters what’s known as an “ultradian trough”—an energetic low point.
  • You start feeling fatigued, groggy, irritable, distracted, hungry, or fidgety. Your attention might wander. Your body might feel heavy, your face slack, your eyes glazed, unfocused, or droopy.
  • You might feel the urge to go to the toilet, or you might experience a sudden craving for sugar, carbohydrates, caffeine, or (if you smoke) a cigarette.
  • You might also hear an anxious little internal voice saying, “Oh dear, it’s only mid-morning and I’m already losing it. How am I going to make it through the day?”

This is a moment to which you want to bring your awareness. Because the feelings you’re noticing right now are signs that your body is working exactly as it should be. These are your body’s flag-waving signals that it needs some down time—now, or as soon as humanly possible—in order to regenerate cellular fuel, rebalance your blood sugar and biochemistry, flush its detoxification systems, and repair damaged tissue.

Your brain also needs a break to sift through all the vast amounts of data you’ve taken in, tag it, organise it, and create important synaptic connections. These are the connections that allow your mental databases to merge and exchange information, producing those magical aha moments, creative insights, and brilliant solutions you kept wishing you had more of. These are the connections that allow important information currently piled up in your various mental inboxes to be sorted, labelled, and filed appropriately so that you can easily recall them later, whenever the need arises. These are the connections that determine whether you are a sparkling genius making great things happen or a grumpy, lumpen mass of flesh parked on an office chair wishing you were somewhere else.

In short, even if you don’t care that much about your health and happiness, if you care at all about your brain and your career, these signals your body is sending you at this moment matter. So now, let’s rejoin your body’s ultradian programme in action:

  • Assuming you heed your body’s signals for a break, the moment you step away from external demands and take a few deep breaths, your body’s internal maintenance goes into high gear, tackling a wide array of internal detoxification, refuelling, and repair tasks that comprise what’s known as the “ultradian healing response.”
  • During the course of the next twenty minutes (ideally), fresh stores of fuel in the form of adenosine triphosphate (ATP) are delivered to your cells; blood sugar, hormones, and neurotransmitters are rebalanced; toxins are flushed; and many important maintenance tasks are completed.
  • At that point, your frontline systems ramp back up and rapidly return to full capacity for another hour and a half or two hours.

But what if you ignore your body’s signals and skip that break?

Research shows that if we ignore our body’s signals, our energy and focus will eventually return to a somewhat higher level of functioning, but not nearly as high as before. After a missed or skimped-on break, our next ultradian performance peak will be significantly lower than our previous one, which means we won’t likely get as much done, or do it as well, and we also won’t feel anywhere near as good while we are doing it. For the next hour and a half or two hours, our body and mind will continue at markedly reduced capacity.

Skipping Ultradian Rhythm Breaks = Diminishing Returns, Escalating Risks

If we miss subsequent breaks as the day wears on, by mid-afternoon, we’re going to be feeling awful and in the grip of a slump from which no amount of coffee or sugar can extract us. Meanwhile, the expense of all this physiological overtime effort will be accruing. We can expect to see:

  • Rising markers of inflammation
  • Increased blood pressure
  • Imbalanced blood sugar and insulin response
  • Higher cholesterol
  • Lowered immunity
  • Imbalanced neurotransmitters
  • Declining mental capacity
  • Gaps in memory
  • Disrupted digestion
  • Imbalanced acid-alkaline levels
  • Slowed metabolism
  • Increased moodiness and emotional reactivity
  • Increased sugar and carb cravings
  • Diminished communication and relational skills
  • Decreased observational capacity
  • Declining motor skills

Additionally, as a result of these operational downgrades, we incur a wide range of secondary costs and risks:

  • We can’t think straight, so our error rate increases, our reading comprehension is reduced, and our productivity plummets.
  • Our peripheral vision narrows, so we miss things we’d normally notice.
  • Our creativity declines, and it takes longer to think of good ideas and solutions.
  • Our physical coordination is reduced, so we type more slowly, produce more typos and transposed numbers; our likelihood of stubbing a toe, spilling our coffee, or having more serious accidents rises precipitously.
  • Our cravings for sugar and refined carbs incline us to eat junk food that further contributes to inflammation and blood-sugar imbalances, reducing our energy and resilience, and leaving us feeling unwell.
  • Disruption of normal sleep patterns and decline in sleep quality further reduce our effectiveness, while further undermining mood, immunity, and cognitive performance.

If we ignore the breaks, we face diminishing returns and increasing risks at every level. The more ultradian rhythm breaks we miss, the more severe the damage. That’s why, by the end of the day, many people are shells of their former selves, walking bundles of numb and frayed nerves. It’s also why so many arrive home after a tough day’s work only to collapse on the sofa, binge on unhealthy food, have several drinks, or end up in irritably tense exchanges with their loved ones.

If we ignore our ultradian rhythms for days, weeks, or months at a time, the accumulated damage and distress become more tangible, producing a variety of nasty potential results:

  • Flaring of inflammatory symptoms, like rashes, cold sores, and lymph-related bumps
  • Back and neck pain, headaches
  • Stomach pain, digestive distress
  • Hormonal imbalances
  • Brain damage and memory loss
  • Mood imbalances
  • Alterations to DNA (activating disease-causing polymorphisms)
  • Accumulation of fat stores, especially around the belly
  • Unconscious obsessive-compulsive behaviours like nail biting, cuticle picking, cheek or lip biting, hair pulling, and scratching
  • Accelerated aging
  • Hair loss and thinning

Eventually, the inflamed and diminished state of the body-mind (caused by the destructive effects of delayed maintenance, repair, and detoxification) can set the stage for serious conditions like heart disease, type 2 diabetes, autoimmune disorders, migraines, arthritis, depression, Alzheimer’s, and more.

But when you think about it objectively, it makes sense that extended ultradian-rhythm mismanagement can play a huge role in degrading our health, sanity, and general well-being: Whenever you repeatedly overdrive and under-maintain any system, it tends to fail.

How Can You Start Listening to Your Ultradian Rhythms?

  • Start noticing that throughout each day, your body moves through a repeating, oscillating energy cycle, rising to an energy peak over an hour and a half to two hours, and then dropping into an energy trough that lasts about twenty minutes.
  • Know that these low-energy troughs are your friend and that they have a purpose: Getting you to take a physical and mental break so that your body can repair, rebalance, replenish, reorganise, and detoxify its core systems.
  • Be on the lookout for signals like fatigue, brain fog, loss of focus and productivity, yawning, fidgeting, difficulty keeping your eyes open, irritation, hunger, thirst, clumsiness, increasing errors, and any kind of bathroom urge.
  • Watch for ultradian troughs to strike in the midmorning and midafternoon (within two hours of starting work and within two hours after lunch). At the first signs of depletion (or ideally, before), stop what you are doing and take a break: Twenty minutes is ideal, but any break (even five or ten minutes) is better than nothing. The longer your break is, the more repair and replenishing work your body will do.
  • Give your body and mind a chance to shift gears. If you’ve been sitting still, move. If you’ve been moving, sit still. If you’ve been focusing intensely, let your brain shut down.
  • Doing manual tasks is okay, but avoid any intensive demands or distractions, including the use of electronics and digital media.
  • Consider setting a timed alert that prompts you to assess your state of energy and focus every ninety minutes or so. Once you become adept at noticing your energetic rhythms, you’ll no longer need an external alert.

Ultradian Rhythm Break Activities

Feel free to combine one or more of the following (based on what your body craves) for a total of ten to twenty minutes, or for however long you can manage:

  • Go to the toilet (even if you don’t think you have to go).
  • Get a drink of water or a cup of tea and enjoy drinking it slowly.
  • Grab a healthy snack (avoid refined carbs and sugars) and eat it away from your desk and while not doing anything productive, demanding, or attention-distracting.
  • Get outside and walk calmly (looking around you, not at your smartphone).
  • Try a walking exercise.
  • Stare into space or out the window, seeing if you notice an interesting shape, colour, or scene.
  • Close your eyes and meditate or do deep breathing.
  • Sit on a curb or bench and let your mind wander for a while.
  • Walk around the building looking for things you never noticed before.
  • Visit with a colleague or friend, expressing interest or positive feelings.
  • Listen to a guided meditation or piece of calming music.
  • Do a little restorative yoga (Shavasana is highly recommended).
  • Do a mindless task, like refilling your stapler or cleaning out your purse or a drawer.
  • Run a simple or pleasant errand (e.g., picking up flowers, shopping for a gift).
  • Rub some lotion or balm into your hands, cuticles, and elbows.
  • Waft some aromatherapy oils or flower essences around your space.
  • Call a loved one to say hi or to express love and appreciation.
  • Visualise how you want the rest of your day or evening to go.
  • Make a quick list of things you are grateful for.
  • Reflect on a list of your core values and notice which ones have been in play today.
  • Consider the body position you’ve been in for the last hour, and assume some contrasting position. If you’ve been leaning forward, stretch backwards. If you’ve been sitting, stand up or lie down. If you’ve been still, move about. If you’ve been looking down, look up. If you’ve been focusing your eyes close-up, look far away.

How the natural environment impacts our brain function, mental health, and cognitive function

Dr Mark Burman – Professor of Psychology at the University of Chicago

Recapturing attention – when attention is fatigued and depleted, we don’t have as much impulse control, we may behave more aggressively, and we may not be able to achieve our goals.

Directed attention:

We are bombarded by so much information that we have to make a choice of what to pay attention to, which humans are really good at, but we have limits on how much and how long we can remain focused. It is estimated that we consume 74GB of information a day. Compare that to 100 years ago, when that amount would have taken a lifetime.

Involuntary attention:

Automatically captured by interesting stimuli in the environment, such as bright lights and loud noises, which we have no control over. This is not affected by fatigue depletion.

Taking a walk in nature is like having a warm-up before doing exercise, it prepares the mind to focus again.

2008 study: To test brain function, walking (without phones or earbuds) in nature compared to walking in an urban environment. The ability to direct attention improved by 20% when walking in nature compared to when walking in the urban environment. The studies were done at different times of year, summer, when people enjoyed the walk and January, when they didn’t want to go for a walk. The results were the same, so it wasn’t mood-related. There is something profound about the way our brains process auditory, visual, and tactile information that is found in nature, which is beneficial for our ability to direct attention. Similar results were found in people with ADHD and those with clinical depression.

It is thought that the fractal patterns (shapes, sounds and even time, that are similar at different scales) found in nature provide softly fascinating stimulation – they allow the mind to wander, which is restorative. However, the man-made urban shapes and sounds are a harshly fascinating stimulation, and they consume all of our attention, which causes fatigue.

The impact of always-on communication devices demands a great deal of our attention because the inputs tend to be numerous and random, and social media channels are steering us in their preferred direction, ultimately to generate profit.

It must also be noted that, although the improvement in attention was not as substantial, viewing a picture of nature and listening to sounds found in nature did enhance attention, but it needed to be done in a different location from your desk or workplace. It was also observed that visiting an art gallery or museum (without phones) yielded similar results. 

So let us map out our day:

Waking and Early Mornings:

We aim to achieve natural positive stress levels in our body and brain through the release of cortisol, adrenaline, dopamine, and acetylcholine.

  • NSDR (Non Sleep Deep Rest) (Dr Andrew Huberman, Professor of Neurobiology and Ophthalmology, Stanford University) protocol or Yoga Nidra (free to download)
  • Meditation (free to download) Dr Wendy Suzuki, Professor of Psychology and Neuroscience at New York University carried out a study on 13 minutes of daily meditation, where participants concentrated on an area just above the forehead and simultaneously focused on nasal breathing. In most cases, the mind would wander, but the important thing would be to bring it back in line with the meditation routine. It was found that this improved focus during the day ahead.
  • Cold shower/bath (spikes dopamine)
  • The mouth biome contains bacteria, especially around the teeth, so floss at least twice a day
  • Don’t look at your smartphone until after breakfast
  • Hydrate (1 litre of water). Add a pinch of sea salt as a source of electrolytes
  • Exercise – walk or run in nature. Exercise is essential for a healthy body and mind and longevity. 10,000 steps is a good target to aim for per day. Add 180 to 200 minutes of Zone 2 cardio per week plus VO2 max (intense aerobic exercise) at least once weekly. 
  • Look towards but not directly at the sun outdoors
  • Have a nutritious breakfast after 1 hour of waking (cortisol inhibits digestion)
  • If you can cycle or walk to work, do that instead of driving your car 
  • Try to find a route to work that takes you through nature
  • To increase cortisol, drink coffee, and to extend the effect, have a grapefruit, but only in the morning
  • If you are feeling groggy, you can increase adrenaline by carrying out rapid inhales and exhales. Take a deep inhale, followed immediately by a deep exhale. Repeat 25 times, then empty your lungs. Hold for 20 seconds and repeat for 5 minutes. Use caution when doing this, as it can cause blackouts.

Organising the morning for deep work:

  • Only deal with the most important emails first thing and leave others for later
  • Switch off your mobile and begin focused work. This will last over 90 minutes, but it can take time to reach the optimal level of performance. It’s better to work in silence, though some people find binaural beats at 40Hz or white, brown, or pink noise helpful (free to download).
  • When using a computer, your eyes work hard during concentrated periods, so remember to maintain good posture, looking slightly down at the screen. Place a picture of nature on a wall where you can see it, and every 20 minutes, focus your eyes on it for 20 seconds. This helps relax your eyes and reduces strain. Learn to recognise when you are in an ultradian trough, usually within two hours of starting work, when you feel fatigue, brain fog, loss of focus and productivity, yawning, fidgeting, difficulty keeping your eyes open, irritation, hunger, thirst, clumsiness, increasing errors, or a bathroom urge. This is the ideal moment to take a 20-minute break. During this break, go for a walk outside—preferably in nature, or if not, visit a museum or art gallery—and while having a coffee or drink, handle any phone calls or pending emails.
  • Depending on when you start work, you might only achieve one period of deep work in the morning, but it’s better to complete a body of quality work than to have to redo it. 

Binaural Beats

Sounds of different frequencies played into each ear. The difference in frequency is called the binaural beat. These waveforms affect the brain in the following way and can be downloaded. 

Delta – 4Hz – helps sleep

Theta – 4 to 8Hz – meditative

Alpha – 8 to 13Hz – increases creativity

Beta – 13 to 30Hz – improves memory & accuracy

Gamma – 30 to 50Hz – improves memory, cognition & mood

Midday to Evening

Many people work through their lunch break, but it isn’t beneficial for you. Turn off your phone and spend your lunch outdoors in nature. If you’re hungry, opt for a low-carb meal to prevent an afternoon slump. Take a walk or join an outdoor exercise session to boost your metabolism and help regulate your circadian rhythm through exposure to natural light.

Resume work aligned with your ultradian 90-minute cycle. After this period, you might feel sleepy, so consider using an NSDR (non-sleep deep rest) protocol for 10–20 minutes to boost dopamine levels and mental energy. Naps are not essential and should be avoided; however, if you do nap, set an alarm for 20 minutes to prevent sleep inertia, which can cause grogginess and low energy.

The purpose of meetings can be categorised into ‘creative’ or ‘administrative’ types. It may be best to hold brainstorming meetings in the morning, when deep thinking can maximise creativity. Conversely, administrative meetings are better scheduled for the afternoon, when cortisol levels are lower. Furthermore, only invite those who will have a direct impact on the meeting’s outcome.

Return to nature for the trip home and leave work behind. Be observant of the colours and shapes you see. 

Eat dinner early so you can fast for at least 12 hours until breakfast. Include some higher-carbohydrate foods and protein to promote relaxation and sleep.

Bedtime and Sleeping

Doctor Matt Walker, Professor of Neuroscience and Psychology, University of California

Begin dimming the lights shortly after sunset and avoid overhead and bright lighting. Reduce computer and phone screen brightness as much as possible. Although research on the effects of blue light from screens on the eyes is inconclusive, glasses that filter blue light are available.

Cool your bedroom by 1–3 degrees below usual and make it as dark as possible, or wear an eye mask. Remove clocks that emit digital light. To encourage relaxation, use the NSDR or perform the physiological sigh as previously explained.

As you fall asleep, you enter a light non-REM stage, followed by deep non-REM sleep. After Then, you return to light non-REM sleep, then enter REM (dream) sleep. The cycle then repeats. As the night progresses, the amount of deep non-REM sleep reduces in favour of light non-REM sleep. 

Studies in sleep deprivation have found that with only 4 hours of sleep in one night, there is a 70% drop in natural killer cell activity – these are immune cells that kill cancer cells, for instance. Proteins such as Amyloid Beta and Tau are allowed to build up, linked to causing Alzheimer’s disease. A study involving 1.6 billion people in 70 countries found that when the clocks go forward and we lose one hour of sleep, there is a 24% increase in heart attacks the following day.

Sleep is the single most effective way to reset your brain and body health. A good night’s sleep depends on:

Quantity – 7 – 9 hours per night

Quality – not impaired by stimulants or anxiety or stress

Timing – chronotype – early or late 

Regularity – within 30minutes each day

Take Aways

  1. Have a regular good night’s sleep 
  2. Eat nutritious food 
  3. Expose yourself to sunlight in the morning
  4. Explore  your inner self through meditation
  5. Take low & high intensity exercise outdoors in nature
  6. Think of stress as enhancing performance
  7. Understand where you are on the Mental Health Continuum
  8. Use breathing techniques to control your heartbeat
  9. Get to know your ultradian rhythm
  10. Be kind to yourself and compassionate to others and smile!

Conclusion

There are many do’s and don’ts and a lot of information to absorb, but the key point is that if you take good care of your body and mind, recognise when you are most effective during the ultradian cycle, and manage your electronic devices—rather than letting them control you—your efficiency and wellbeing will improve during the working day. This will ultimately lead to better results at work and an improved bottom line. 

The Fundamentals of Sleep

Much of this post is taken from research by Dr Matthew Walker – UC Berkeley with protocols by Dr Andrew Huberman – Stanford School of Medicine.

Sleep Fundamentals: QQRT

Quantity: the total amount of sleep. The typical adult needs 7 to 9 hours of sleep per night, which gives sufficient time for deep sleep and REM sleep, so you wake up refreshed and restored. Some people need less, others more, especially babies, teens, and those combating an illness or infection.

Quality: the continuity and structure of sleep. Frequent awakenings (even if you don’t remember) or fragmented sleep represent poor sleep quality.

  • Wearable sleep trackers measure sleep quality through sleep efficiency scores. An efficiency rating of ≥ 85% is a good goal.
  • Note: For some, sleep trackers can lead to anxiety about sleep quality (termed “orthosomnia”), which can paradoxically lead to disrupted sleep. Consider reviewing your sleep scores less often. For example, weekly, not daily, to minimise constant monitoring.
  • For those who don’t use sleep trackers, poor sleep quality often manifests as excessive daytime sleepiness even if they slept sufficient total hours.

Regularity: stick to a consistent sleep schedule. Consistently going to bed and waking up at a similar time each day improves overall sleep patterns and quality by anchoring your body’s circadian rhythm, or internal clock.

  • Aim for consistent bedtimes and wake times with a ± 30 minutes margin of error, whether it’s the weekend or a weekday. No one is perfect about this, but that’s a good goal.
    • In addition to your morning alarm clock, consider adding a “bedtime alarm,” which tells you when to go to sleep.
  • Studies have shown that regular sleep patterns reduce all-cause mortality and may reduce the risk of cancer and cardiovascular disease more effectively than other metrics, such as sleep duration.

Timing: align your sleep schedule with your natural chronotype (morning person, night owl, versus typical sleep-wake schedule). Chronotype is primarily determined by genetics, and yet your preferred sleep time will vary across your lifespan. You can find your natural chronotype using the Morningness-Eveningness Questionnaire (MEQ). Sleeping out of sync with your chronotype will result in poorer quality sleep. But, of course, we have to adhere to life’s demands as well.

What  Happens When You Fall Asleep?

Data on the two types of sleep was published in 1954, then in the 1960s William DeMent carried out studies and coined the name REM (Rapid Eye Movement). Every time someone went into REM sleep they would be woken to do a mathematical task. After day three of selective REM sleep deprivation they started to show signs of paranoia, then to have hallucinations and delusions and by day five they were having aspects of severe psychosis.  This research was summed up by an American entrepreneur called E Joseph Cossman. He summarised it in a single sentence as ‘the best bridge between despair and hope is a good night of sleep’ and to this day that’s exactly what the data demonstrates in terms of basic emotional brain function.

In the first 20 minutes of falling asleep, you enter non-REM sleep, which has four stages, 1 & 2 are light and 3 & 4 are deep non-REM. During these first 20 minutes, your heart rate slows and brain wave activity reduces. After 20 minutes you enter stages 3 & 4 and your heart rate drops dramatically,  muscle tone drops and hundreds and thousands of cells in the Cortex all fire up and then go silent. At around 60 to 70 minutes into the sleep cycle, you return to stage 2 non-REM and at around 90 minutes go into REM sleep. 

Just before you enter into REM sleep a signal is sent through the brain stem to the alpha motor neurons in the spinal cord to prevent them from working. This effectively paralyses your body during this dreaming phase allowing you to dream safely. Your involuntary muscles are not paralysed ensuring you can breathe and your heart continues to beat, nor are the eye or ear muscles paralysed. 

This sleeping cycle continues throughout the night with more 3 & 4 non-REM in the first half of the night and more 1 & 2 non-REM in the second half, along with more REM sleep.

Sleep Deprivation

One of the earliest and strongest effects of a lack of sleep is the absence of motivation, not interacting with the world, not wanting to be social, not wanting to learn, not wanting to exert effort, not wanting to exercise, not wanting to do much of anything.

A lack of sleep will impact every physiological system in your body and every operation of your mind. If limited to 4 hours for one night, there will be a 70% drop in natural killer cell activity; these cells are critical anti-cancer immune cells. A global experiment called Daylight Savings Time is carried out twice yearly in 70 countries with 1.6b people participating. In the Spring, when 1 hour is lost of sleep, there is a 24% increase in heart attacks the following day. Conversely in Autumn, when 1 hour is gained in sleep, there is a 24% decrease in heart attacks. It has also been noticed that in the Spring not only is cardiovascular health at risk, but there is also an increase in diabetes and obesity, poorer mental health, lower cognitive performance, and an increase in the risk of motor vehicle accidents. Lack of sleep reduces levels of testosterone in men and oestrogen in women, and systolic blood pressure increases along with heart rate contractions. The progression into obesity diabetes, cardiovascular disease, mental health issues, anxiety, depression, suicidal ideation, and immune-compromised infection will be mid-term consequences with a longer-term slide into premature mortality.

A group of healthy people with no signs of psychiatric illness or emotional instability were given a full night of sleep and the next day they were placed inside a brain scanner and shown a range of emotional visual images ranging from very neutral to quite unpleasant and negative. The study was to see how the brain reacted to those emotional experiences with and without sleep.  The structure that was initially focused on was the amygdala situated on the left and the right side of the brain. The amygdala is the centrepiece region for the generation of emotional reactions both positive and negative but this study focussed on the adverse, negative aspect. In people who were sleep-deprived relative to those who had a full night of sleep, there was a 60% increase in emotional response rate. This was a dramatic heightening of sensitivity to the initial triggering of the emotional response, and the more the emotion became the more separate the two sets of reactivity curves came from the amygdala.  The question then became why is the amygdala so reactive and uncontrolled when you are absent of sleep? Another analysis was carried out and a structure in the frontal lobe that sits right between your eyes, the medial prefrontal cortex, was investigated. This acts like a control rational mechanism on the deep emotional brain centres, placing the context to an appropriate or inappropriate reaction to a situation. With sleep deprivation, it was found that the connection had been severed so the emotions could not be modulated effectively. A Japanese research group replicated this more rigorously and their published findings had the same response.

Sleep Hygiene Basics

Light & Dark

The hormone Melatonin has many functions, one is to make you sleepy. Darkness allows the release of melatonin to signal the onset of sleep. Bright light, especially at night, potently inhibits melatonin. This causes you not to feel as sleepy and, consequently, to get poorer quality sleep.

  • In the evening, dim the lights in your home to signal the body that it’s time to wind down. Avoid viewing bright overhead lights between 10 pm and 4 am. Here is a simple rule: only use as much artificial lighting as is necessary to move about safely at night. Use low-positioned lights (rather than overhead) and yellow or, even better, deep orange/red lightbulbs, if available; they are less stimulating than typical lights.
  • Minimise screen time at night. If you’re on a screen, dim it way down. Additionally, many computer operating systems show warmer colours at night. There are also apps like f.lux (zero-cost) that allow for dimming. This also applies to mobile phones, if possible leave your phone outside the bedroom.
  • Add blackout curtains or wear an eye mask to maximise darkness in the bedroom.
  • Within 30-60 minutes of waking, go outside for 10-15 minutes of morning sunlight. Sunlight suppresses Melatonin and resets your circadian rhythm. Morning sunlight also triggers Cortisol release to help you wake up and stay more alert during the day. On overcast days look towards where the sun will be as plenty of light (photons) penetrate cloud cover. On bright cloudless days: view morning and late afternoon sun for 10 min; on cloudy days: 20 min; on very overcast days 30-60 min. Consider an artificial daytime simulator source if you live somewhere with minimal light.  If you wake up before the sun is out and want to be awake, turn on artificial lights and then go outside once the sun rises.
  • Looking through an indoor window does not work. Don’t wear sunglasses for this practice if you safely can, but contact lenses and eyeglasses are fine. Don’t look directly at the sun, and never look at ANY light so bright it is painful to view!
  • If you can’t get natural morning sunlight due to geographic location or schedule, artificial bright lights like seasonal affective disorder (SAD) lamps are a substitute, though less effective.

Temperature

Temperature plays a crucial role in sleep regulation and to fall asleep, core body temperature must decrease by approximately 2-3°F (1°C).

  • Keep your bedroom cool (~67°F or ~19.4°C), or use a temperature-controlled mattress cover.
  • Place your hands or feet from underneath the covers to help cool down.
  • Taking a warm bath or shower before bedtime is a science-supported method to improve your ability to fall asleep and improve deep non-REM sleep. The warm water initially raises core body temperature, but subsequent cooling occurs to help to fall asleep.

Food & Meal Timing

The effect of food on sleep largely depends on appetite, circadian rhythm, and personal preference. Experiment with different foods and timing to see what best supports your sleep.

  • For most, eating approximately 2 hours before bedtime doesn’t typically impact sleep. Eating closer to bedtime can increase the likelihood of gastric reflux (heartburn) and impair sleep in some individuals. Again, this is highly individual. If you do, make it a smaller snack or meal, but also don’t try to sleep while overly hungry. Most people can’t.
  • Avoid excessive fluid consumption before bedtime to reduce the likelihood of waking up throughout the night.

Caffeine

The health benefits associated with coffee drinking are good from a health perspective. However, it has nothing to do with the caffeine, It’s because the coffee bean contains a large dose of anti-oxidants, the most powerful being chlorogenic acid. Studies with decaffeinated coffee give very similar health benefits so drink caffeine but limit yourself to about 2 cups of coffee, 3 cups of coffee maximum. Caffeine is a stimulant it does not reduce the need for sleep; it only temporarily masks sleepiness. Once caffeine wears off, a buildup of adenosine, a chemical that promotes sleepiness, causes a “caffeine crash,” which usually occurs in the early afternoon.

  • The timing of drinking caffeine is crucial for sleep quality. So, if you have trouble sleeping, don’t reach for a late afternoon cup of coffee. Instead, consume caffeine early in the day and not within 8-10 hours of bedtime. caffeine has a quarter-life of somewhere between 10 to 12 hours so if you have a cup of coffee at midday a quarter of that caffeine is still in your brain at midnight
  • Note: some people say they can sleep after ingesting caffeine in the afternoon or evening. This is likely due to tolerance and/or differences in how they metabolise caffeine. Do what works for you, but know it can negatively affect sleep structure, including REM duration.

Alcohol

Alcohol is a sedative, not a sleep aid. While a ‘nightcap’ may help you get to sleep quickly, alcohol impairs the natural structure of sleep. You don’t remember how you have slept but the quality is poor alcohol is very good at blocking your REM sleep and disrupting your deep non-REM sleep. Also, even the smallest amount of alcohol causes fragmented sleep.

Taking Naps

Naps can improve cardiovascular health, lower blood pressure, and improve your learning and memory abilities. Negative emotions can be de-escalated and positive emotions increased. However, be careful if you take naps. Try not to nap for longer than 20 minutes because once you go past 20 minutes you fall into the deepest stages of non-REM sleep. If you wake up after about 45 minutes or 60 minutes you’re going to feel almost miserable and worse than you did before the nap because you have sleep inertia, essentially a sleep hangover and it can take you almost an hour before you feel like you’re back up to operating normally. In addition, don’t nap too late in the afternoon (3 pm) and if you’re someone who has insomnia or sleep difficulties do not nap because when we’re awake during the day we build up a sleepiness chemical called adenosine and the longer that we’re awake the more adenosine builds up. After sleeping a full night the brain has evacuated all of the adenosine so that when we wake we feel refreshed and restored. When you take a nap you’re releasing some of that healthy sleepiness

Wind-Down Routine

Much like slowing down a car before stopping, a ‘deceleration’ from the day’s activities is essential for good sleep. Establish a wind-down routine to prepare the body and mind for sleep:

  • Engage in relaxing activities, such as meditation, listening to music, podcasts, sleep stories, or reading a book.
  • Avoid stimulating activities before bed, such as watching television, reading the news, strenuous exercise, or social media.
  • Expect to feel alert ~1 hour before your natural bedtime. This is a naturally occurring spike in wakefulness that sleep researchers have observed and will pass.

Trouble Falling Asleep?

Walk It Out: If it’s taking longer than ~20-25 minutes to fall asleep or back asleep, leave your bed and go elsewhere in the house to engage in a relaxing activity. The goal is to prevent an association between a state of wakefulness and your bed, as this can lead to future difficulties falling asleep. Only return to bed when you are truly sleepy and be mindful not to fall asleep in another location; you want to relearn the association of sleep with the bedroom.

Do Nothing: After one poor night’s sleep, avoid compensatory behaviours such as sleeping later, going to bed early, increasing caffeine intake, or excessively long or late-day napping. These behaviours can disrupt your natural circadian rhythms and may negatively affect sleep-wake cycles—in other words, they will make it hard to get back on your usual schedule.

Mental Walk: If you have trouble falling asleep, take a “mental walk” and visualise walking a familiar route. This technique will redirect your focus away from ruminating thoughts to help you fall asleep.

Other Help – YouTube. If you wake up in the middle of the night and cannot fall back asleep, consider doing a Non-Sleep Deep Rest (NSDR) protocol when you wake up. Enter “NSDR” into YouTube and the top 3-4 options have different voices and durations for you to select from. Or do a “Yoga Nidra” protocol (enter “yoga nidra” into YouTube).

Limit Daytime Naps: Keep naps short (≤ 20-30 minutes) and no later than the early to mid-afternoon to avoid impacting your nighttime sleep.

If you try these protocols and don’t notice a difference, you might be suffering from a sleep disorder. Seek professional help if you experience persistent problems, which might be due to sleep apnea or true insomnia.

Cleansing the Brain

Sleep expert Dr Matt Walker (professor of neuroscience at the University of California, Berkeley) says,

‘We have not been able to discover a single psychiatric condition in which sleep is normal so there is a direct relationship between your sleep health and your mental health’.

One of the functions of emotions when it comes to memory is to prioritise that experience instructing the brain that this information is relevant to us as an organism. During good quality sleep between the initial experience and the later recollection of that emotional memory, the brain has divorced the emotion from the memory so on recollection at a later time, the emotional memory is no longer as powerfully emotional as it was at the time of the experience. The sleeping brain can detox the emotional memory. In a study, a biological model of exactly how this works was carried out studying a sleep group that had eight hours of sleep which was measured. It was found that the greater the amount of REM sleep the greater the amount of emotional detox experienced the next day. 

Something utterly unique happens during sleep, with levels of noradrenaline completely shut off, the only time during 24 hours there is a complete cessation of adrenaline in the brain. (The chemicals noradrenalin (UK) and norepinephrine (US) are the brain equivalent of adrenalin and epinephrine found in the body). The neuromodulator Serotonin is also blocked. So the stress-related chemicals in the brain are switched off during REM sleep.

However, levels of another chemical Acetylcholine increase in the brain. Acetylcholine also acts at various sites within the central nervous system, where it can function as a neurotransmitter and a neuromodulator. It plays a role in motivation, arousal, attention, learning, and memory. There is almost a 30% increase in some brain regions than when awake pointing to REM sleep as the perfect condition for emotional overnight therapy where you can reactivate, experience and process those emotional memories in a chemically safe environment that allows you to strip away the emotion. 

This resembles behavioural desensitisation therapy used to treat trauma, whereby under the care of a qualified psychiatrist or psychologist somebody will be encouraged to recall in great detail some traumatic event and through repetition and with support will be allowed to encounter the experience safely over several sessions so the emotional load of the event is diminished

To be your best emotional self and access positive emotions to their full amplitude, the best and cheapest non-psychological way to enhance your sleep is to sleep an extra 15 or 20 minutes.

Anxiety

Anxiety is probably one of the greatest enemies of sleep and is one of the principal reasons that underlies insomnia. If you have stimulants in your system before going to bed such as alcohol, drugs or caffeine your fight-or-fight branch of the nervous system is triggered and you feel what is called the tired but wired phenomenon. You start to worry, then you start to ruminate and when you ruminate you catastrophise and when you catastrophise you are awake for the next two hours or so. We have the sense that in the darkness of night, things are so much bigger than they are in the brightness of day and we start worrying. A study on the consequences of a cup and a half of strong caffeine intake before bed showed it strips away your deep sleep by somewhere between 15 to 30% . To put that into context if you drop your deep sleep by 30% it would be the same as ageing you by about 40 years. Even if you fall asleep and you stay asleep you’re not aware of the lack of deep sleep that you’re not getting because of the caffeine. Deep sleep is critical for regulating your cardiovascular system and replenishing the immune system, it also regulates your metabolic system, controlling hormones such as insulin that will regulate your blood sugar. Deep sleep will strengthen, consolidate and secure new memories in your brain preventing those memories from being forgotten, deep sleep is also the time when we cleanse the brain of metabolic toxins, particularly those related to Alzheimer’s disease. 

Suicide

It has been found in studies that insufficient sleep is a precursor to suicide. Sleep disruption seems to predict suicidal ideation; suicidal thinking, suicide planning and tragically suicide completion as well.

PTSD

Paul Conti, the renowned psychiatrist, defines trauma as some adverse event that changes the way that our nervous system works such that we function less well in the future. The diagnostic criteria for PTSD is not just being able to fall asleep it’s specifically having repetitive nightmares. As mentioned earlier, in normal REM sleep noradrenalin is switched off and emotions are stripped away from the memory. However, it has been found that PTSD patients have heightened levels of noradrenalin as a basal state as well as during REM sleep so the trauma remains a vivid emotion linked to the memory.

Alzheimer’s Disease

Whilst diet and genetic factors dictate the risk of developing Alzheimer’s in later life, there is causal evidence both in animal models and in human models that if a human being is deprived of deep sleep for a single night the risk of developing Alzheimer’s increases. Sleep deprivation causes an immediate increase in the two proteins, beta-amyloid and tau associated with the development of Alzheimer’s, circulating in the bloodstream and cerebral spinal fluid that bathes the brain. Maiken Nedergaard, professor of neuroscience at the University of Rochester, USA discovered the brain has a cleansing system called the glymphatic system named after glial cells that make it up. This system is switched into overdrive during deep non-REM sleep and washes away the build-up of beta-amyloid and tau proteins. If you’re not getting enough good quality sleep every night it doesn’t mean that you’re going to get Alzheimer’s disease next week or in a year but over time it is now believed through this causal mechanism that insufficient sleep is a risk factor for Alzheimer’s disease. 

Rachel’s Reviving Remedies

In February 2024 I was invited by AVIXA to speak on a panel at ISE 2024, about mental health in the workplace. Although not an expert in this field, there has been much written on the subject and I shared my findings with the audience. I have included links to my favourite sources but there are many more for you to discover.

There have been several traumas in my life and most go back to my childhood. This is quite common and whilst traumas are often different they trigger a similar response in all of us and are the most common cause of long-term stress, depression and suicide. Gloomy or what? Do not be dismayed it can be reversed and there are remedies for short-term stress and ways of building resilience against medium-term stress. However, if you feel you cannot cope seek medical advice, especially for long-term stress.

Our responses to a situation depend on the context of what is happening. If the situation is traumatic the surrounding narrative should be shared with those you trust or written down. Internalising the trauma will prolong the shame and the blame we all attach to it.

You have to start somewhere and you may be surprised by what my list consists of but it is all backed up by expert research, see links provided. I also recognise we have to live our lives in our own way and this is just a guide to help us improve our mental state and longevity.

  1. On awakening try and remember your last dream and write it down. 
  1. Go outside for a morning walk, preferably within 1 hour of waking and if possible surrounded by nature, fields or trees – 4,000 steps or more is OK.  
  • Look towards the sun, or if overcast where the sun would be for as long as is practicable. This suppresses melatonin and resets your circadian rhythm. It also triggers the release of cortisol to help you wake up and stay alert during the day.
  • If you meet someone wish them good morning, strike up a conversation or at least smile.
  • Links: Dr Andrew Huberman – https://www.youtube.com/ watch?v=WDv4AWk0J3U
  1. Good quality nutrition, how much you eat and when you eat is essential for brain function and a healthy body. 
  • Cut out ultra-processed foods completely. 
  • Boost your gut biome and include amino acids, and protein, at least 30 different fruits and vegetables per week, this can be nuts, spices, herbs, vegetables, fruits and berries. You can also have lean meats and omega-3 fatty acids like oily fish for instance. 
  • Introduce fermented foods such as yoghurt, kefir, kimchee, sauerkraut and kombucha.  
  • Reduce the amount of alcohol consumed. 
  • There are three natural pathways for you to need to consume sugar and the brain’s preferred food is glucose. The food companies know this and put sweeteners in foods and drinks (including zero sugar) to trigger your brain to want more. Be aware too much sugar is bad for you and you will receive the right amount by eating the aforementioned. 
  • If you drink coffee make sure it is during the day, preferably the morning, to enable a good night’s sleep. 
  • Arrange a time of fasting every day, perhaps finish eating at 8 pm and have breakfast at 8 am. This gives the body and brain time to remove dead cells, build muscle from the day’s exercise and repair systems. The longer the fast the better the repair.
  • Links: Dr Andrew Huberman – https://www.youtube.com/watch?v=xjEFo3a1AnI,  Dr Michael Mosley – https://www.youtube.com/watch?v=DpnOVX0Dc5E, Professor Tim Spector – https://www.youtube.com/watch?v=xGY05t_sImc&t=22s
  1. After 40 years of age, you reduce muscle mass, speed and power so exercise is essential for a healthy body and mind and longevity. Daily movement, either cardiovascular or resistance training is very important. 
  1. We are sociable mammals and regular social interaction can impart many emotions to lift mood and happiness and increase metabolic rate and neural output. However, at work, for instance, there is no choice but to interact, therefore be aware of those you interact with. People can be grouped into three sections, those who give you net savings on stress (you feel at ease with), those who are neutral and those who are taxing. Try to avoid those in the taxing section. Link: Dr Lisa Feldman Barrett – https://www.youtube.com/watch?v=FeRgqJVALMQ&t=7385s
  1. Stress happens to all of us and there are tools to help manage and alleviate acute stress. The quickest and easiest way to alleviate acute stress in real-time is the physiological sigh, this immediately slows the heart rate down. Medium-term stress can be handled by training oneself to cope better under stress conditions. This involves taking cold showers or plunges and whilst immersed practising the physiological sigh to bring you to a state of normality. The more you practice the better you will be at regulating and coping with stress.  For long-term stress or at any point where you feel you cannot cope, seek qualified medical help. Links: Dr Andrew Huberman – https://www.youtube.com/watch?v=ntfcfJ28eiU, Dr Peter Attia & Dr Paul Conti – https://www.youtube.com/watch?v=HoGBkn_1Z14&t=6s
  1. You need good sleep to allow your brain and body to rejuvenate itself. The important factors here are the quantity, the quality, the regularity and timing (Chronotype) of sleep (QQRT). Try having 7 to 9 hours of the best possible sleep per night (no phones allowed). This should be in a darkened bedroom. Go to bed and arise within 30 minutes of your sleep routine to form a habit and enhance your circadian rhythm. Temperature plays a large part in sleeping and your bedroom should be cool – around 19°C. Place arms, hand and feet outside of the covers, take a hot bath or shower before going to bed – this will actually cool down your core temperature.

The Six Pillars of Mental Health

A daily routine to look after your biology – In my research I came across podcasts by Andrew Huberman, Ph.D and was impressed by the sheer output of subjects, that are peer reviewed and have a bearing on our well-being. He is a neuroscientist and tenured professor in the department of neurobiology, and by courtesy, psychiatry and behavioural sciences at Stanford School of Medicine. He has made numerous significant contributions to the fields of brain development, brain function and neural plasticity, which is the ability of our nervous system to rewire and learn new behaviours, skills and cognitive functioning.

Here is my summary of Dr Huberman’s Six Pillars of Mental Health:

  1. Sleep – Try having 7 to 9 hours of best possible sleep per night. Have a sleep routine to maximise this and form habits. Go to bed and arise within 1 hour of your habitual pattern to enhance your circadian rhythm.
  2. Light – view sunlight as early as you can after waking in the morning for between 10 and 20 minutes – you need to be outside to do this as windows filter out the lightwaves your brain needs. This practice will put you in a better mood and increase your focus and alertness. It will also help you to sleep at night. (Do not stare directly at the sun. If there is no sunlight face east in the lightest part of the sky). Darkness is as important when you retire to sleep – no lights, no looking at phones for 6 to 8 hours.
  3. Exercise – 180 to 200 minutes of Zone 2 cardio per week (low intensity, where you can just hold a conversation) plus VO2 max (intense aerobic exercise) at least once weekly. Daily movement, either cardiovascular or resistance training is very important. You can have 1 day of rest per week.
  4. Nutrition – consume sufficient amounts of calories per day ensuring it is quality nutrition. Macronutrients, proteins, fats, carbohydrates and micronutrients. Cut out ultra-processed foods altogether. Include cold fermented food, in your diet to boost your microbiome (Kefir, Miso, Sauerkraut, Kimchi etc). (Heating this will kill the live cultures).
  5. Social interactions – we are sociable mammals and regular social interaction can lift mood and happiness and increase metabolic rate and neural output. However, at work, for instance, we have no choice but to interact, therefore be aware of those you interact with. People can be grouped into three sections, those who give you net savings on stress (you feel at ease with), those who are neutral and those who are taxing. Try to avoid those in the taxing section.
  6. Stress Control – Stress happens to all of us and there are tools to help manage and alleviate acute stress. The quickest and easiest way to alleviate acute stress in real-time is the physiological sigh, this immediately slows the heart rate down. Medium-term stress can be handled by training oneself to cope better under stress conditions. This involves taking cold showers or plunges and whilst immersed practising the physiological sigh to bring you to a state of normality. The more you practice the better you will be at regulating and coping with stress.  For long-term stress or at any point where you feel you cannot cope, seek qualified medical help.
