Sleep hygiene: A series of practices and non-medical treatments for insomnia. Sleep hygiene includes simple steps that may improve initiation and maintenance of sleep, such as maintaining a regular sleep schedule, making the bedroom an inviting place to sleep, avoiding alcohol or smoking prior to going to bed, and exercising regularly (but not in the 4-5 hours prior to bedtime).
