How to build a bedtime routine
Last reviewed: 14 September 2026
A bedtime routine is not really about relaxing. Its job is to tell your body that sleep is coming, which is why the order matters more than what is in it.

Tell it when you have to be up and it works your whole evening backwards — last coffee, last big meal, screens off, wind-down, lights out.
Why a routine works at all
A bedtime routine is not a relaxation ritual, though it can be relaxing. Its actual job is signalling. Doing the same sequence in the same order at roughly the same time lets your body start preparing before you get into bed — core temperature falling, melatonin rising — so that by lights out the preparation is already done.
That is why the order matters more than the contents. A predictable sequence of dull steps beats a varied set of pleasant ones, because prediction is the mechanism.
What goes in it, and when
Working backwards from lights out:
| Before lights out | What | Why |
|---|---|---|
| 8 hours | Last caffeine | Half-life of 5–6 hours, so half of a mid-afternoon coffee is still active at bedtime. |
| 3 hours | Last big meal | Lying down on a full stomach is uncomfortable and worsens reflux. A light snack is fine. |
| 2 hours | Last hard exercise | Core temperature and adrenaline stay elevated afterwards. Gentle movement or stretching is fine, and walking is positively helpful. |
| 90 minutes | Dim the lights | Lamps instead of overhead lighting. Evening light delays the body clock, and ambient brightness matters more than people expect. |
| 60 minutes | Work and screens off | Mostly about displacement rather than blue light — content designed to be hard to stop is hard to stop. |
| 30 minutes | Wind-down begins | Shower or bath, teeth, reading. Same order nightly, finishing in the bedroom. |
| 0 | Lights out | In bed, settling. Most people take 10–20 minutes to fall asleep. |
A warm bath or shower about 90 minutes before bed is one of the better-supported wind-down steps, and it works in the opposite way to how it feels. Warming your skin sends blood to the surface, which helps core temperature fall afterwards — and a falling core temperature is one of the physiological signals for sleep.
Building one you will actually keep
- Start with the last 30 minutes only. A seven-step evening programme is abandoned within a fortnight. Three steps in a fixed order survives.
- Anchor it to a fixed lights-out time, which comes from your wake-up time rather than from when you happen to feel tired. The sleep calculator will give you that.
- Finish in the bedroom. Whatever the last step is, do it there, so the room is where the sequence ends.
- Keep the order identical. Contents can vary; sequence should not.
- Do it on bad nights too. The routine is worth most when you least feel like it, because that is when the signal is doing the work.
Routines for children
The same principle, with more repetition and more ceremony — children are considerably more sensitive to sequence than adults, and will treat any variation as an opening to negotiate. Twenty to thirty minutes is plenty at any age under about ten.
What changes across childhood is the content and the timing rather than the structure. Our bedtimes by age pages cover each year individually, including the routine that suits it — from a 1-year-old's bath-milk-books sequence to the household rules that replace a routine entirely by the teenage years.
Wind-down and evening routines: the same thing?
Roughly, yes. "Wind-down" usually refers to the last hour before bed, and "evening routine" to the whole stretch after dinner. The useful distinction is that the wind-down is the part that directly affects sleep, and it is the part worth protecting when the evening runs late.
If you get home at 9:00 PM and lights out is 10:30 PM, drop the evening routine and keep the wind-down. Thirty predictable minutes beats ninety chaotic ones.

Common questions
How do I start a sleep routine?
Work backwards from a fixed lights-out time, and start with the last 30 minutes only. Three steps in an unchanging order, finishing in the bedroom, is more likely to survive than an elaborate programme. Add earlier steps once the short version is habitual.
How long before bed should a bedtime routine start?
The wind-down itself needs about 30 minutes. Working further back: screens and work off an hour before, lights dimmed 90 minutes before, no hard exercise within two hours, no big meal within three, and no caffeine within about eight.
What should a good bedtime routine include?
Dim light, no work or screens, and a short predictable sequence — a warm shower or bath, teeth, and reading is a reliable one. The specific steps matter less than doing them in the same order at roughly the same time.
Does a warm bath before bed help you sleep?
Yes, and it is one of the better-supported wind-down steps. Warming the skin about 90 minutes before bed helps core body temperature fall afterwards, and falling core temperature is one of the signals for sleep.
What's the difference between an evening routine and a wind-down?
Wind-down usually means the last hour before bed; evening routine covers the whole period after dinner. The wind-down is the part that directly affects sleep, so it is the part to protect when the evening runs late.
