Your core temperature has to drop about 1°C for sleep to start. A bedroom at 18–19°C gives it somewhere to go — most people sleep in rooms that are simply too warm, then wonder why they toss for an hour.

Set a wind-down alarm, not just a wake-up alarm
An alarm 45 minutes before lights-out beats relying on willpower. When it rings, screens go away and the wind-down starts — same cue, every night. Your brain learns the sequence the way it learned that the kettle means coffee.
Light and audio wind-down routines that cue your brain for sleep.
Do one 4-7-8 breathing cycle in bed
Slow exhale-weighted breathing activates the parasympathetic nervous system — the physiological brake. Four seconds in, hold for seven, eight seconds out. One or two rounds is enough; this is a brake pedal, not a meditation retreat.
Park tomorrow's worries on paper
A five-minute brain-dump of tomorrow’s to-dos helped people fall asleep significantly faster in a controlled study — the more specific the list, the faster the sleep onset. Your brain stops rehearsing what it knows is written down.

Get bright light within an hour of waking
Tonight’s sleep is set this morning. Bright light early in the day anchors your circadian clock, so melatonin rises on schedule in the evening. Ten minutes outside beats an hour of dim indoor light — cloudy counts.
What didn't make the list
Genuinely useful for jet lag, but tolerance builds fast with nightly use and timing matters more than dose. As an every-night crutch it underperforms everything on this list.
The ritual helps (see the wind-down alarm); the chamomile itself barely moves the needle in trials. Drink it because you like it, not because it works.
Questions people ask
10–20 minutes is typical. Under 5 suggests you are sleep-deprived; consistently over 30 is worth taking to a doctor, especially with daytime fatigue.
The room temperature and morning light picks help with night wakings as well. Waking at 3am with a racing mind responds best to the paper brain-dump — keep the notepad within reach.
