I've spent the last year taking sleep seriously.

Not obsessively. Not perfectly. Just deliberately.

It's had a huge impact. I've seen a roughly 48% increase in restorative sleep, without spending more time in bed.

The single biggest change I made? I go to bed at roughly the same time every night.

I don't chase wake-up times. That takes care of itself when bedtime is stable.

Why it matters

When you sleep well, your brain clears waste, locks in learning, sharpens decision-making and steadies your mood. Your body repairs tissue, regulates hormones, supports immunity and recovers properly.

When sleep is poor, all of that degrades quietly in the background, and is linked to a higher risk of cardiometabolic disease, cancer and early mortality. It's the biggest longevity lever most of us ignore, which is exactly why sleep sits at the base of the whole pyramid, not somewhere near the top with the supplements.

What surprised me most wasn't that sleep improved. It was how little I had to do to get there.

Go to bed at the same time every night.

What I changed, and in what order

There were other things too, but only after I'd nailed consistency:

  • Bedroom cold (window open, fan), dark (eye mask) and quiet (ear plugs)
  • Occasional hot shower before bed
  • No caffeine after lunch
  • No alcohol, bar the odd big night out
  • More balanced training: less high intensity, more Zone 2 when recovery was low
  • Magnesium and creatine
  • Phone out of bed, red-light filter on

Notice the order. Bedtime consistency did most of the work on its own. Everything else was a smaller, later adjustment on top of a habit that was already holding. If you read our piece on why recovery isn't a product, this is that argument, but as the actual data from one very tired CEO.

"Same life. Same training. Same workload. Better sleep quality. Less drag. Better recovery."

The results

Six months at a time, tracked and compared.

Restorative sleep
2h29m → 3h41m
72 more minutes of REM and deep sleep, per night.
Sleep consistency
75% → 83%
133 days in the optimal (80%+) range.
Sleep debt
1h23m → 0h35m
A 58% reduction. Low debt (under 30 min) on 65 days.
Sleep performance
72% → 87%
A 15-point improvement. My best six months on record.

Same life. Same training. Same workload.

Better sleep quality. Less drag. Better recovery.

Sleep on purpose

None of this required a sleep clinic, a new mattress or a device strapped to my arm telling me things I already suspected. It required picking one behaviour and holding it for long enough to see what happened.

That's the whole method, and it's the same one we coach members through in The Big Sleep Project, our six-week programme built on exactly this order of operations: one habit, held properly, before adding the next.

Sleep on purpose. Everything else gets easier from there.

Build the Foundations

Coaching-led, class-based training scaled to the individual, backed by the same principle behind this: get the basics right before you chase anything else.
