Sleep Is a Business Decision

Some people still brag about sleeping five hours. After two decades working with entrepreneurs and executives, we have learned to read that sentence for what it is: a competitive advantage handed to the competition. Because while you cut sleep to work more, your brain cuts exactly the functions you need to work well.

What you actually lose when you sleep less

Sleep deprivation does not just make you tired. It degrades, in order, the abilities a decision-maker values most: working memory, risk assessment, emotional control, creativity. After a week of five to six hours a night, cognitive performance is comparable to that of someone who has been drinking. With one cruel difference: the chronically under-slept stop noticing. You feel functional. You are not.

Sleep is where today's work becomes tomorrow's capability

During deep sleep the brain consolidates what you learned, clears metabolic waste, and rebalances stress hormones. During REM sleep it processes emotions and connects distant ideas — the solution that comes to you in the shower is born there. Cutting sleep means taking in input all day and deleting the processing every night.

The levers that actually work

A fixed wake-up time. Regularity matters more than quantity. Wake at the same hour, seven days a week, and the rest tends to fall into place.

The right light at the right time. Full, preferably natural light in the first hour of the morning. Low, warm light in the last two hours of the evening. Your internal clock is set this way — not by willpower.

A boundary between work and bed. The last email read at midnight is not productivity: it is a thought that will spin in your head until one. You need a shutdown ritual — even just writing tomorrow's three priorities and closing the laptop.

Watch alcohol and late dinners. Alcohol sedates but fragments deep sleep. A heavy dinner at 10 p.m. forces your body to digest when it should be recovering.

In practice

• Choose a wake-up time and protect it, weekends included.

• Ten minutes of natural light within an hour of waking.

• Last two evening hours: dim lights, no email, no decisions.

• Alcohol away from bedtime; dinner finished at least two hours before sleep.

• Track how you wake up for two weeks: it is the best indicator you have.

Sleep is not time stolen from work. It is the process that turns hours of work into results. Treat it like the strategic asset it is.

If you have been waking up tired for months and it feels normal — it is not. At Re·Vive Gran Canaria, recovery is where every programme begins.
