Sleep
Insomnia is a general term for difficulty falling asleep and/or staying asleep. Insomnia is the most common sleep problem, with many adults reporting occasional insomnia, and 10–15% reporting a chronic condition. Insomnia can have many different causes, including psychological stress, a poor sleep environment, an inconsistent sleep schedule, or excessive mental or physical stimulation in the hours before bedtime. Insomnia is often treated through behavioral changes like keeping a regular sleep schedule, avoiding stimulating or stressful activities before bedtime, and cutting down on stimulants such as caffeine. The sleep environment may be improved by installing heavy drapes to shut out all sunlight, and keeping computers, televisions and work materials out of the sleeping area.

Behavioral treatments tend to be the most prescribed and the most cost-efficient of all treatments; these treatments include exercise, cognitive behavioral therapy, relaxation therapy, meditation, and improving sleep hygiene. Improving sleep hygiene includes making the patient sleep regularly, discourage the patient from taking daytime naps, or suggesting they sleep in a different position.
