What Is Sleep Hygiene? (And Does It Work?)

Sleep hygiene refers to behaviours and environmental factors that support consistent sleep.

Common Elements

Typical recommendations include:

1. consistent sleep timing
2. reduced evening light exposure
3. limiting caffeine late in the day
4. maintaining a cool sleep environment

What Actually Matters

Sleep hygiene works best when the behaviours are consistent rather than perfect.

Infrastructure Close

Sleep hygiene is less about rules and more about building stable signals the brain can recognise every night.
