Sleep hygiene

Sleep hygiene is a set of daily habits and bedroom conditions meant to make good sleep more likely: a steady schedule, a dark and cool room, limiting late caffeine and alcohol, and a wind-down period. It has nothing to do with cleanliness. Think of it as setting the stage for sleep, not forcing it.

For general sleep health, the habits are sensible and low risk. For diagnosed insomnia, the evidence for sleep hygiene on its own is weak, and clinical guidelines point to CBT-I as the first-line treatment. It is a reasonable foundation, but if you have struggled for weeks, it probably will not be enough alone.

No. Sleep hygiene is education about habits and environment. CBT-I is a structured program that typically includes techniques like stimulus control, sleep restriction, and work on sleep-related worry. CBT-I programs often include hygiene advice, but the behavioral techniques are what do most of the heavy lifting.

Poor habits can make sleep worse and help keep a sleep problem going, but they are rarely the whole story. Stress, medical conditions, medications, mental health, and other sleep disorders all play a role. If tidying up your habits does not help, ask a clinician instead of piling on more rules.

If poor sleep happens several nights a week, lasts a few weeks or longer, and affects your days, get it checked. The same goes for loud snoring, gasping at night, or severe daytime sleepiness. Those can point to problems that no amount of bedroom tweaking will fix.
