Bedtimes are for the night before your alarm. Each includes about 14 minutes to fall asleep, so you wake at the end of a complete 90-minute cycle instead of in deep sleep.
Go to bed at 11:16 PM for 7.5 hours of sleep. That is 5 complete 90-minute cycles — the amount most adults feel best on.
Tips for the 7:00 AM schedule
Protect the last hour, not just the bedtime. An 11:16 PM lights-out fails if 10:30 PM is still work email and bright screens. Blue-enriched light after 10:00 PM delays melatonin by up to 90 minutes — effectively moving your bedtime to nearly 1:00 AM without you noticing. Night-mode filters help, but dimming the room helps more.
Keep wake time sacred, bedtime flexible. If there is one rule sleep researchers agree on, it is this: wake at 7:00 AM every day, including weekends. A fixed wake time anchors your body clock; your bedtime will then drift to the right place on its own through natural sleepiness.
Use the commute as a light cue. Whether you walk, drive, or take the train, facing daylight during the morning commute reinforces the rhythm. Remote workers should fake a commute: a 10-minute walk right after the 7:00 AM alarm works just as well.
Frequently asked questions
Is 11:16 PM to 7:00 AM healthy long-term?
Yes. It is 7.5 hours of sleep with a consistent schedule — and consistency is arguably as important as duration. Large population studies link regular 7–8 hour sleepers with the best health outcomes; irregular schedules, even with the same total hours, score worse.
I go to bed at 11:16 PM but lie awake — now what?
If you are awake after about 20 minutes, get up, go to a dim room, and do something boring until you feel sleepy. Lying in bed awake trains your brain to associate bed with wakefulness — sleep therapists call the fix “stimulus control,” and it is one of the most effective insomnia techniques that exists.
Can I catch up on weekends?
Partially. One or two longer nights reduce the immediate sleep debt, but they don’t fully repay weeks of short sleep — and sleeping until 10:00 AM on Sunday makes Monday’s 7:00 AM alarm brutal. Keep weekend lie-ins under one extra hour.
