Wind-down planner
What it does
The wind-down planner turns your lights-off time into the hour before it: when the quiet hour starts, when the bath or shower goes in, when the phone goes on charge somewhere else, and the one alarm that makes the whole thing happen. It's a bedtime routine for adults with the deciding taken out.
- Set your lights-off time When the lamp goes off, not when you go upstairs.
- Tick the parts you will actually do Nobody does all of it every night. Pick two and keep them.
- Set one alarm, for the start of the hour Not an alarm to go to bed. An alarm to go up and begin.
An hour is easy to agree with and hard to notice. You mean to wind down. Then it's 11.05 and the email is still half written.
The planner does the one thing a checklist can't. It puts a time against each step. The evening gets an edge.
How to use it
Put in your lights-off time. If you don't know it, the sleep calculator works it back from your alarm. Tick the steps you want.
The planner lays them out in order. The bath or shower window, one to two hours before bed. The quiet hour, starting an hour before lights off, with the big light off and the lamps on.
The phone on charge in another room. Five minutes on tomorrow's list.
A ritual to open the hour, an hour before bed: the same warm drink in the same mug, the same chair, the lamp. Then something that ends, such as a paper book or a podcast on a timer.
The answer at the top is a single alarm time, for the start of the hour. Name it "upstairs".
When it goes off, you stand up. The end of the hour takes care of itself.
What the evidence says about each step
The hour itself is NHS advice: relax for at least an hour before bed. The bath window comes from a 2019 review of 17 studies.
Warm water at about 40°C, one to two hours before bed, shortened the time to fall asleep by just under ten minutes on average. Later than that and you're still warm when you lie down.
The phone step comes from a lab study of 12 adults. They read on a bright tablet for four hours before bed, took longer to fall asleep, and their body clocks ran later. Four hours is more than most of us manage, so take it as the direction rather than the size.
The list comes from a 2018 study. Five minutes writing tomorrow's to-do list got people to sleep faster than writing about tasks already done.
The ritual comes from a 2018 review of the psychology of rituals. A ritual is a fixed sequence, done the same way each time. It has at least one step with no practical purpose, and your attention is on the senses.
The review's reading of the experiments is that the attention is what settles people. That's why the planner puts the same mug and the same chair at the start of the hour, and asks nothing of the drink itself.
The order matters more than the contents. A 2012 review in the British Journal of General Practice describes how habits form.
Repeat a simple action in the same setting, and the setting starts to prompt it. Done nightly, the sequence becomes the brain's cue that the shift is ending.
What it can't do
Nobody has measured the hour. It's a sensible convention. Whether 40 minutes or 90 would do is untested.
The planner helps most with getting off to sleep. If your night breaks at 3am instead, winding down makes less difference, and why the two problems differ explains what does.
Each step, with the studies at their true size, is in how to wind down before bed. The whole evening is in how to build an evening routine that sticks.
The ritual is in why a bedtime ritual works better than a routine. Nothing you type here leaves your browser.

Questions
What should a bedtime routine for adults include?
Fewer things than you'd think. The NHS suggests a bath or a book. The trials add a to-do list and a warm shower an hour or two before bed. Pick two or three and keep them in the same order, because the order is the part your body learns.
When should you start winding down?
An hour before lights off, as the NHS advises. The planner sets that as the alarm. A bath goes earlier, one to two hours before bed, so you've cooled down by the time you lie down.
What if you're not sleepy when the hour ends?
Stay up. Go to bed when you're sleepy, not when the routine ends; some nights that's later, and that's fine. If you're wide awake after about 20 minutes in bed, get up and sit somewhere dim until you are.
