Wind-down and a fixed wake time
You can't decide to fall asleep, but you can decide when to get up. Learn why the wake time is the anchor, how to build a wind-down that works, and how to nap without wrecking the night.
THE ANCHOR
Fix the wake time, not the bedtime
Your wake time is the one end of the night you can actually hold. Get up at the same hour and two things follow: you take your morning light at the same hour, which holds the clock in place, and you finish building sleep pressure at the same hour, so the gate from lesson 1 opens at roughly the same time each night.
Keep it on your worst nights too. Slept badly? Still get up. You'll be tired that day, but the extra pressure buys you a better night, which is exactly what you need. Sleeping in to repair a bad night is what turns one bad night into a bad fortnight.
Two ways to build a schedule
Fixing the bedtime
You get into bed at 10:30 whether you're sleepy or not. On the nights your pressure is low you lie there for an hour. Your actual sleep time still moves around, and you've taught yourself that bed is a place you lie awake.
Fixing the wake time
You get up at 6:45 whatever happened last night, and go to bed when you feel the yawns. Bedtime settles by itself within a couple of weeks, because pressure and clock are both landing at the same hour.
Check yourself
Saeed decides to fix his sleep. His plan: in bed at 10:30 sharp every night. Two weeks later he's still awake at midnight most nights and getting up at anything from 6 to 8. What's the better plan?
- Get up at 6:45 every day and go to bed only when he's sleepy
- Keep the 10:30 bedtime and wait; his body will learn it eventually
- Hold both a fixed 10:30 bedtime and a fixed 6:45 wake time, exactly
- Go to bed even earlier, at 10, to give sleep more chance to arrive

Get up at 6:45 every day and go to bed only when he's sleepy
Yes. The wake time is the end he can control, and it sets both his light and his sleep pressure. Bedtime then settles on its own instead of being enforced.
THE RUNWAY
A wind-down is a landing, not a switch
Your body needs time to come down. Work, screens, arguments and planning all keep the alerting system running, and it doesn't stop the second you turn off the light. A wind-down is 30 to 60 minutes of the same quiet things every night, so that by the time you get into bed your body has already begun the descent.
The point isn't which activity you choose. It's the repetition. Do the same three things in the same order for two weeks and they start to work as a signal in themselves, the way the smell of dinner makes you hungry.
A 45-minute wind-down you can copy
- Draw a finish line
Pick the time the day stops: 10:15 for an 11pm bed. Work, messages, news and difficult conversations end there. The line matters more than what's on either side of it.
- Take the house down a notch
Ceiling lights off, one warm lamp on. Phone on charge in another room. Tomorrow's clothes out, teeth done, kitchen tidy. Boring on purpose.
- Twenty quiet minutes
A paper book, stretching, a warm shower, prayer, slow music, or sitting and talking with someone. Anything that doesn't ask you to decide, compete or win.
- Go when the wave comes
When your eyes get heavy, go. That's the gate from lesson 1 opening, and it doesn't wait for you.

A wind-down works because the activities in it are relaxing, so it doesn't matter whether you do them in the same order each night.

False
Half right, and the missing half is the important one. The calm helps, but most of the power is in the repetition: the same sequence at the same hour becomes something your body reads as 'night is starting'. A different relaxing thing every evening never becomes a signal.
Power nap
A short sleep of 10 to 20 minutes, taken before mid-afternoon. Short enough that you stay in the light stages and wake up clear, early enough that your sleep pressure has hours to build back before bedtime. It takes the edge off a short night without borrowing from the night ahead.
Mahsa sleeps badly before an exam, naps 15 minutes after lunch with an alarm, and is sharp through the afternoon. A 90-minute nap at 6pm would have left her groggy and then wide awake at midnight.

Which naps pay for themselves?
- 20 minutes at 1:30pm after a short night
- An hour and a half at 6pm
- 10 minutes in a chair at 2pm, alarm set
- Dozing off on the sofa at 8:30pm with the TV on
- A short nap before a long evening drive
- A 'quick lie down' at 4pm with no alarm

Helps: 20 minutes at 1:30pm after a short night, 10 minutes in a chair at 2pm, alarm set, A short nap before a long evening drive
Costs you the night: An hour and a half at 6pm, Dozing off on the sofa at 8:30pm with the TV on, A 'quick lie down' at 4pm with no alarm

Niloofar sleeps about 6 hours on weeknights and struggles to drop off. She's started a 45-minute nap at 4pm, wakes from it groggy, and then lies awake even longer at night. What should she change?
- Drop naps completely and push through the afternoon however she feels
- Keep the 45 minutes but move it to 6pm, nearer to bedtime
- Stretch it to 90 minutes so she wakes at the end of a full cycle
- Make it 15 minutes, straight after lunch
Show the answer
Make it 15 minutes, straight after lunch
Right on both counts. Fifteen minutes keeps her out of deep sleep, so no grogginess, and an early-afternoon nap leaves her a long stretch of the day to rebuild sleep pressure.
Putting the three together
- The wake time is the anchor. Set it, keep it on bad days too, and let bedtime follow your sleepiness.
- Go to bed when you're sleepy, not when the clock says so. Lying there awake teaches your body the wrong thing, which is what lesson 10 is about.
- The wind-down is a runway: 30 to 60 minutes of the same quiet things in the same order, starting at the same hour.
- Naps are short and early: 10 to 20 minutes, before mid-afternoon, with an alarm.

Match each habit to what it actually does
Show the answer
- Getting up at the same time every day → Holds the body clock in one place
- The same three quiet things before bed → Becomes a signal your body learns to read
- 15 minutes of sleep after lunch → Takes the edge off without emptying the night
- An hour asleep on the sofa at 7pm → Drains the pressure you'll need at 11
Lesson recap
- You can't decide to fall asleep. You can decide when to get up, and that's the anchor for everything else.
- Keep the wake time even after a bad night; the extra sleep pressure is what fixes the next one.
- A wind-down of 30 to 60 minutes works through repetition: same things, same order, same hour.
- Go to bed on sleepiness, not on the clock.
- Nap 10 to 20 minutes before mid-afternoon. Longer or later, and you pay for it that night.
