Sleep for executives: how sleep shapes CEO decision-making, and how to protect it

Sleep debt and judgement: why you do not notice it

The American Academy of Sleep Medicine and the Sleep Research Society recommend at least seven hours of sleep a night for adults. Many executives run on six, and feel fine. That feeling is the problem.

In a well-known 2003 laboratory study, Hans Van Dongen, David Dinges and colleagues restricted healthy adults to six hours a night for two weeks. Their performance on attention tests fell steadily, until it resembled that of people kept awake for a full night or more. Their own ratings of sleepiness, however, rose only a little. Chronic short sleep degrades performance faster than it degrades your sense of how you are doing.

Sleep loss affects the capacities a leader relies on most:

• Sustained attention, the ability to stay with a long document or a long meeting.
• Emotional regulation: small frictions provoke bigger reactions.
• Flexibility: sticking with a plan after the evidence has changed.
• Self-assessment: believing you are sharper than you are.

For CEO sleep and decision-making the practical lesson is simple: important, irreversible decisions deserve a rested mind, and 'sleep on it' is a legitimate method, not a delay.

How to sleep better as an executive: the routine that holds

The routine that survives a demanding calendar is short:

• Fix your wake time, including at weekends, within about an hour. It anchors your body clock more than the time you go to bed.
• Get daylight in the first hour after waking, outdoors if you can.
• Build a buffer of thirty to sixty minutes before bed with no email and dim light.
• Keep the bedroom cool, dark and quiet. In a hot climate, the air conditioning is part of your sleep routine.
• Write down tomorrow's open loops before bed, so your mind does not have to hold them.
• If you cannot sleep after roughly twenty minutes, get up, read something dull in low light and go back when sleepy.

Caffeine and alcohol: the two levers you control

Caffeine

Caffeine blocks the build-up of sleep pressure, and its effect lasts much longer than the buzz. Its half-life in adults is typically around five hours, with wide variation between people. A 2013 study by Christopher Drake and colleagues found that caffeine taken six hours before bedtime still disrupted sleep noticeably. A simple rule is no caffeine after early afternoon, and less of it on days you are already anxious.

Alcohol

Alcohol helps you fall asleep and then damages the rest of the night: it suppresses REM sleep early, fragments the second half and worsens snoring. The drink that 'helps you unwind' after a dinner with clients is often the reason you wake at four in the morning. If you drink, drink earlier in the evening, drink less, and watch what it does to your sleep and your heart rate variability the next day.

Travel and jet lag: sleep strategy from a Dubai hub

Dubai sits within a few time zones of Europe and Asia, which makes it a hub, and gives executives based there a steady stream of jet lag. London is three or four hours behind depending on the season, Singapore four ahead, New York eight or nine behind. The body clock adjusts by roughly an hour a day, and flying east, where you have to go to sleep earlier, is usually harder than flying west.

• For trips of two or three days across a few time zones, consider staying on Dubai time for sleep and scheduling key meetings in your own best hours.
• For longer trips, shift to local time on arrival and use light as the main tool: morning light after flying east, evening light after flying west.
• Avoid alcohol on the flight and keep caffeine to the local morning.
• Do not schedule the most important decision for the first morning after a long eastward flight if you can avoid it.
• Melatonin has reasonable evidence for jet lag across several time zones, but rules and doses vary by country: ask your doctor before using it.

When to suspect sleep apnoea or insomnia, and see a doctor

Obstructive sleep apnoea, in which the airway repeatedly closes during sleep, is common and often undiagnosed, especially in men, after middle age and with weight gain or regular alcohol. It fragments sleep without waking you fully. See a doctor if you notice:

• Loud, regular snoring, or a partner who sees you stop breathing or gasp.
• Waking unrefreshed or with a headache despite enough hours in bed.
• Falling asleep in meetings, on calls or, most dangerously, while driving.
• High blood pressure that is hard to control.

Diagnosis needs a sleep study, and effective treatment exists. Insomnia that lasts for weeks deserves the same seriousness: cognitive behavioural therapy for insomnia (CBT-I) is the first-line treatment in major clinical guidelines, ahead of sleeping pills. Persistent low mood with poor sleep is also a reason to see a professional, not to try harder.

How the Cosmic Wolf Institute works on recovery

The institute's image of the human bio-battery is, in corporate terms, recovery reserve: the capacity a leader draws on during the day and has to refill at night. Sleep is the main way it refills. The institute's practices sit around that foundation, not in place of it.

In the programmes, that means slow breathing and Cosmic Meditation aimed at neurophysiological coherence, practised to help the nervous system come down from a day of pressure, with HRV as a way of following recovery over weeks. The institute describes the calm state it trains as alpha-theta, a direction of training rather than a promise. It connects this with temporal density: fewer, deeper hours of leadership are only possible from a rested state.

The seven-day boot camp on Lake Victoria is built around the conditions that good sleep needs: nature, full board, breathwork and seven days away from the stimulation that keeps the nervous system on alert. None of this is medical treatment, and it does not replace a sleep study when symptoms call for one.
