Sleep: the bedrock of your wellbeing

Hi there,

How did you sleep last night? 

Every August, I see the same pattern playing out: people finally take a holiday, sleep in for the first time in months, and come back saying "I didn't realise how tired I was!" That's not a coincidence. It's a sign that most of us are running on a sleep deficit we have simply stopped noticing.

This month on the podcast, I've been focusing on sleep, rest and breaks - not as nice-to-haves for your annual leave, but as the foundation everything else in your wellbeing and performance is built on. 

The bedrock, not the bonus

It is tempting to think of sleep as one wellbeing habit among many - alongside exercise, nutrition, social connection and so on. But the evidence increasingly points to something different: sleep is not one ingredient among equals, it is the foundation the others sit on. Skimp on sleep and you undermine the return on everything else you are doing for your wellbeing.

Neuroscientist Matthew Walker puts it starkly: if the benefits of a good night's sleep could be bottled as a pill, it would be the most sought-after drug on the market. And yet most of us treat sleep as the first thing we sacrifice when work gets busy, rather than the thing that protects our capacity to cope with busy periods in the first place.

What actually happens while you sleep

While you sleep, your brain is not resting - it's arguably working harder than when you are awake. It is consolidating what you have learned during the day, making connections between new information (which is where creative breakthroughs often come from), and processing your emotions. Meanwhile, your body is using sleep to repair and reset every major system - nervous, digestive, circulatory, muscular.

This is precisely why sleep has what we might call an image problem. You can see someone eating a healthy lunch or going to the gym - it is visible, shareable, obviously virtuous. Nobody can see the repair work happening while you sleep. So it's easy to underrate something whose benefits are invisible, and easy to ignore the cost of not doing it until it shows up somewhere else entirely: a short temper, a mistake, a headache you cannot explain.

The cost is closer than you think

We tend to motivate ourselves with long-term health arguments, and long-term arguments are notoriously easy to discount ("That's a problem for future me" - sound familiar?). Sleep is different: the consequences of a bad night show up almost immediately.

A single night of poor sleep measurably affects your mood, your short-term memory and your ability to regulate your emotional responses - in other words, your capacity to collaborate well with other people the next day. And this is not about single bad nights: consistently getting less than the seven to nine hours adults generally need is linked to a marked increase in chronic disease and, as sobering as it is, a meaningfully higher risk of early death.

None of this is about panicking over the occasional restless night. It is about noticing the pattern, and recognising that regularly sacrificing sleep is not a performance strategy - it's the opposite of one.

Reframing rest as strategic, not indulgent

One of the most useful reframes for anyone leading a team, or simply trying to justify rest to themselves, is to stop thinking of sleep and rest as a reward for having earned it, and start treating them as strategic.

When we rest - even without sleeping - the brain's default mode network activates, supporting problem-solving, creativity and emotional intelligence. A well-timed 20-minute rest or nap is not time off from performance; it is an input to it. There is even evidence from clinical settings that medics who were able to nap during a shift were measurably more effective afterwards.

If the term "self-care" does not sit well with you, try performance improvement instead. Rest, sleep and self-compassion are ingredients of better decision-making, fewer errors and better conversations - which is, ultimately, what most of us are actually trying to achieve.

A practical toolkit for improving your sleep

As in all aspects of wellbeing and performance, small, consistent changes tend to beat dramatic ones. So here are a few worth experimenting with, as discussed with Dr. Fiona Jane Meechan on Ep 221 of 'My Pocket Psych':

1 - During the day

• Get outside in natural daylight in the morning - it helps regulate your body clock.
• If you exercise, earlier in the day is better than right before bed.
• Be mindful of caffeine timing rather than cutting it out altogether - it has a long half-life, so that mid-afternoon coffee may still be affecting you at midnight.
• Keep alcohol and heavy meals to at least a couple of hours before bed.

2 - In the hour before bed

Try breaking it into three loose 20-minute phases.

• Put the day to bed: tidy up, prepare for tomorrow, and try a brain dump, writing down what is on your mind and what you will do about it tomorrow. Research suggests this can meaningfully speed up how quickly you fall asleep.
• Wind down physically: a warm shower (it contributes to a drop in your core body temperature afterwards, which aids sleep) or some gentle stretching.
• Properly relax: reading a book, listening to some music, or engaging in any other relaxing hobby.

3 - Your environment

Your sleeping environment can make all the difference. Cultivate an environment that actively promotes sleep: a cool room, as dark as you can make it (an eye mask is a small, cheap game-changer), and quiet or consistent background noise if silence is not realistic.

The point is not to do all of this perfectly. It is to treat it as a menu, find what works for you, and hold it loosely enough that missing one element does not itself become a source of anxiety.

The takeaway

Sleep and rest are not things you earn once the to-do list is finished. They are the conditions that make good work - and a good life - possible in the first place. If wellbeing and performance matter to you, sleep is where that starts. And it's why I include workshops on sleep in all the wellbeing programmes I run. 

You can find out lots more about the role of sleep and rest when it comes to wellbeing and performance by checking out the latest episodes of 'My Pocket Psych':

• In Ep 221 I was joined by Dr. Fiona Jane Meechan to discuss the role of sleep in our wellbeing and performance
• In Ep 222, I explored different non-sleep ways to build rest into your routines
• In Ep 223, I looked the why it's important to take a break before you need one!

As we leave summer behind, try to identify your own personal 'sleep recipe', the collection of habits that lead to a better night's sleep for you. Then sit back and notice the difference it makes to your day.
