Most cases of insomnia are related to poor sleep habits, depression, anxiety, lack of exercise, chronic illness, or certain medications.
Symptoms may include difficulty falling or staying asleep and not feeling well-rested.
Treatment for insomnia consists of improving sleep habits, behavior therapy, and identifying and treating underlying causes. Sleeping pills may also be used but should be monitored for side effects.
