The Two-Week Sleep Reset
In about two and a half weeks, an alarm goes off at 6:30am in a house that's forgotten what 6:30am is, and the first fortnight of term is brutal for everyone in it. It doesn't have to be. But the fix starts now, because the thing you're trying to move doesn't move quickly.
Your body runs on an internal clock, set primarily by light. Six weeks of later nights and later mornings has pushed it back by an hour or more. Decide on 1 September to go to bed at 10:30pm and you'll lie there wide awake, because your clock still thinks it's early evening and hasn't started releasing the hormone that makes you sleepy. You can't decide to be tired.
What you can do is move the clock. It moves at about 15 to 20 minutes a day, no faster — which is exactly why a two-week runway is the right amount of time.
Move bedtime back by 15 minutes every two days. Going to sleep at 11:30pm and want 10:30pm? Four steps over eight days. Bigger jumps just produce an hour of lying awake in the dark.
Get outside within an hour of waking. Morning daylight — even on a grey Chilterns morning, even through cloud — tells the clock the day has started and pulls everything earlier, including the time you'll feel sleepy that night. Ten minutes. Walk round the block or have your coffee in the garden.
Take the light out of the evening. Bright overhead lights and screens after 9pm tell your clock the opposite thing. Use the blue light filter on the phone and dim the lights.
Sleep is what lets you tolerate load. It's when your body repairs the work you did, and it's the difference between training three times a week for a year and getting injured in October.
Two weeks. Fifteen minutes at a time. Start tonight.
