The Complete Sleep Hygiene Checklist (12 Habits)
"Sleep hygiene" sounds like a buzzword, but it's just the boring, repeatable stuff that decides whether tonight's sleep is good or garbage. Here are a dozen habits, ranked by how much they tend to matter.
The big three (do these first)
- Consistent schedule. Same wake time every day is the single strongest anchor for your clock.
- Dark, cool room. Aim for a bedroom around 18–20°C (65–68°F) and as dark as you can make it.
- No late caffeine. Caffeine's half-life is ~5–6 hours; a 4 p.m. coffee is still half in you at 10 p.m.
The middle six
- Morning light. 10–20 minutes of sunlight soon after waking.
- Wind-down hour. Dim screens, lower lights an hour before bed.
- Reserve the bed for sleep. No laptops, no scrolling.
- Cut evening alcohol. It helps you fall asleep then fragments sleep later.
- Regular exercise. Earlier in the day beats late-night workouts.
- Limit fluids late. Fewer 3 a.m. bathroom trips.
The last three (nice-to-have)
- A consistent pre-sleep ritual (tea, stretch, journal).
- Magnesium glycinate if you're short on it.
- A white-noise or fan for steady background sound.
Don't boil the ocean. Pick two from the big three this week. Hygiene compounds — small consistent wins beat one perfect night.
Not medical advice. Chronic insomnia often needs CBT-I (cognitive behavioral therapy for insomnia), which outperforms pills — ask a clinician.
