About this evidence tier
This is a provisional editorial rating for the general practice, not proof that it treats a condition. Research citations will be attached after source-level review. Use the safety notes and judge the practice by your own tracked response.
Fixed wake times, a cool dark room, and a calm evenening routine are the backbone of sleep. Consistency trains the clock more than any single trick.
