The Sleep Hygiene Checklist: 20 Things to Fix Tonight

What sleep hygiene actually means

Sleep hygiene is an unglamorous name for a simple idea: sleep works best when your environment and your habits stop fighting it. No single item below will transform your nights, and that's the point — hygiene is the accumulated effect of a dozen small frictions removed. If you came here looking for in-the-moment techniques instead (breathing patterns, the 20-minute rule), our guide to falling asleep faster covers those; this checklist is about the setup.

Work through it once, in order. Each section is a real checklist — count what's already true, and fix one or two things at a time rather than all of it tonight.

The bedroom checklist

Your bedroom is the stage sleep happens on:

• Cool: around 18°C (65°F) suits most people — your core temperature needs to drop for sleep to begin.
• Dark: blackout curtains or an eye mask; even small light sources register on a sleeping brain.
• Quiet — or consistently masked: a steady sound like rain or crickets beats unpredictable silence.
• Phone out of reach and face down, or ideally out of the room entirely.
• Bed reserved for sleep: if you regularly work or scroll in it, your brain files it under awake places.

The daytime checklist

Sleep is built during the day, which is why half of this checklist happens before dinner:

• Wake at the same time every day, weekends included — within about an hour.
• Get outside light in the morning; it's the strongest signal that sets your body clock.
• Last caffeine roughly eight hours before bed — its half-life is longer than it feels.
• Move your body most days; even a walk measurably builds sleep pressure.
• Keep naps short and early — twenty minutes before mid-afternoon, not an hour at 6 p.m.
• Go easy on alcohol near bedtime; it sedates at first, then fragments the second half of the night.

The evening checklist

The last hour before bed is where hygiene turns into ritual:

• Dim the lights one to two hours before bed — light is your brain's main daytime signal.
• Run the same short wind-down sequence nightly; repetition turns it into a sleep cue.
• Start your sleep sound early, as part of the routine rather than an afterthought.
• Write down tomorrow's loose ends so they don't audition for your attention at midnight.
• Keep the routine small enough that you'll actually do it on your worst day.

The in-bed checklist

Once the light's off, only a few rules still apply:

• If you're awake after roughly twenty minutes, get up briefly rather than marinating in frustration.
• Turn the clock face away — clock-watching is anxiety with numbers.
• If your mind is wired, two minutes of slow breathing beats thirty minutes of frustration.
• Let the sleep timer fade your sound out; silence should arrive slowly, not all at once.

How to use this list without obsessing over it

The paradox of sleep hygiene is that perfectionism makes sleep worse. Pick the one or two items that are most obviously broken — for most people it's the wake time and the phone — and give them two weeks before touching anything else. The rest of the list will still be here.

And the honest caveat: sleep hygiene supports sleep, but it doesn't cure insomnia. If you're lying awake three or more nights a week for three months or more, that's chronic insomnia, and the recommended first-line treatment is CBT-I — a structured therapy that outperforms hygiene tips alone. A doctor can point you toward it.
