The 24-Hour Sleep Checklist
Good nights start in the morning. This checklist covers the whole day, from when you get up to lights out, and every item is based on current sleep research. Enter your wake-up time and it works out the timing for you. Your ticks are saved on this device.
Morning
Set your body clock
-
A fixed wake time anchors your body clock more firmly than anything else. Your bedtime follows from it.
-
Morning daylight sets the timing of tonight's melatonin. Outdoor light is far brighter than indoor light, even when it's overcast, and a window cuts a lot of it.
-
Daytime activity builds the sleep pressure that helps you drop off later.
Daytime
Protect tonight's sleep
-
A 2023 meta-analysis worked out that a regular cup of coffee should be finished almost 9 hours before bed to avoid cutting into sleep. For a high-dose pre-workout it was over 13 hours.
-
Short, early naps refresh you. Long or late ones spend the sleep pressure you need at bedtime.
-
A 2019 review found evening exercise didn't hurt sleep. The exception was vigorous sessions that ended within about an hour of bedtime.
Working from home
Replace what the commute did
-
Home workers lose the daylight a commute used to give them for free.
-
A clear finish line stops work thoughts from leaking into your wind-down.
-
Your brain learns what bed is for. Answering email there teaches it that bed means alert.
Evening
The last three hours
-
Lying down on a full stomach invites reflux and restless sleep.
-
Alcohol makes you drowsy, then breaks up the second half of the night and cuts into REM sleep.
-
Ordinary room lighting delays melatonin. Turning the lights down does more than any blue-light filter.
-
A 2019 review found a warm bath or shower 1 to 2 hours before bed helped people fall asleep about 10 minutes faster. The cool-down afterwards is what does it.
-
Fewer 3 AM bathroom trips.
Bedroom
Cool, dark, quiet, boring
-
Your core temperature has to drop for you to fall asleep and stay asleep.
-
Even dim light through closed eyelids can lighten your sleep.
-
Steady sound covers up the sudden noises that wake you.
-
Blue light isn't the main problem with phones. The bigger one is that there's always one more thing to look at.
-
Checking the time at 3 AM turns being awake into worrying about being awake.
Wind-down
The last 45 minutes
-
In a 2018 Baylor University study, people who wrote a to-do list at bedtime fell asleep about 9 minutes faster than people who wrote about what they'd already done.
-
Feeds and inboxes are built never to end. A book chapter or one episode does.
-
One buzz at the wrong moment can undo the whole wind-down.
-
Slow breathing calms your nervous system. Do it to relax, not as a test you can fail.
-
Most adults need at least 7 hours of actual sleep, so give yourself 7½ to 8 hours in bed.
Next morning
How rested do you feel? 1 is wrecked, 5 is great. It shows up in your week above.
If you can’t sleep
- Get up after about 20 minutes. If you've been awake for what feels like 20 minutes, go to another room, keep the light low and do something dull. Go back to bed when you feel sleepy.
- Don't check the time. Knowing it's 3:12 AM never helped anyone fall back asleep.
- Stop trying. You can't force sleep. Lie there and rest. Effort just wakes you up more.
- Keep tomorrow's wake time. Even after a rough night, get up on time and skip the long nap. The sleep pressure you build will help you sleep the next night.
Talk to a doctor if…
- Loud snoring, gasping or choking at night, or someone has seen you stop breathing. These are signs of sleep apnea.
- Trouble falling or staying asleep at least 3 nights a week for 3 months or more. Ask about CBT-I, the treatment the American Academy of Sleep Medicine recommends for chronic insomnia.
- Nodding off when you don't mean to, especially behind the wheel.
- An uncomfortable urge to move your legs in the evening that eases when you move them.
A checklist can’t fix a sleep disorder. If any of these sound familiar, see your doctor or a sleep clinic. Start with what sleep apnea looks like.

Making it stick
- Don't try all 24 tonight. Pick the 3 to 5 you're missing most, stick with them for a week, then add more.
- Aim for most days, not perfect days. Getting 80% done most nights beats 100% done twice.
- Look at your sleep tracker's weekly trend, not each night's score. Chasing a perfect score can keep you up.
- If you use CPAP, wear it every night, all night, and do the cleaning routine in your evening block.
