Sleep hygiene is a set of habits and environmental choices that make sleep easier—consistent schedule, low evening light, a cool and quiet bedroom, limited late caffeine/alcohol, and a calming wind-down routine.
Why This Matters
This matters because sleep is sensitive to cues: light, temperature, timing, and stress. Good hygiene reduces arousal and strengthens circadian signals, which leads to faster sleep onset and fewer awakenings. It also gives you leverage before you reach for medication or supplements.
Where This Changes
Hygiene helps many people, but it won’t fix everything if a medical disorder (apnea, restless legs) is the main cause. If your “sleep hygiene” becomes perfectionism (orthosomnia), it can increase anxiety and worsen sleep—keep it practical and flexible.
