Sleep hygiene is the set of habits and surroundings that make sleep more likely: consistent timing, calmer evenings, a comfortable room, and better control over light, caffeine, food, and activity.
These changes do not replace medical care for a sleep disorder, but they are often the first practical step and can make other treatments work better.
