Why sleep hygiene matters (and what it actually is)

Sleep hygiene sounds clinical, but it just means the daily habits that set up good sleep. It is not a prescription — it is a set of choices about light, timing, caffeine and routine that make falling asleep easier and sleep deeper.

It is about the day, not just the night

What you do in the morning and afternoon shapes the night. Waking at a steady time, getting daylight, and moving your body all anchor your body clock — so that by the evening, your brain is ready to sleep.

The big levers

• A steady bedtime and wake time, even on weekends
• A consistent wind-down before bed
• Less screen light in the hour before sleep
• A cool, dark, quiet bedroom

None of these is dramatic on its own, but together they make the environment and routine work for you instead of against you. Print a nightly checklist on the sleep checklist page and start with the two that feel easiest.
