It can be normal to have trouble sleeping from time to time, but if you are having trouble sleeping most nights, you may have a sleep problem. Sleep problems can affect your quality of life, and some can pose a serious threat to your health if left untreated.
If you think you might have a sleep problem, discuss your symptoms with your healthcare provider. After reviewing your sleep history, your healthcare provider may refer you to a specialized sleep center or lab, where trained technicians will perform a sleep study. Sleep studies are tests that monitor your sleep, either overnight or during a series of naps during the day. These tests are painless and used to diagnose sleep problems such as insomnia, sleep apnea, or narcolepsy. Depending on the circumstances, some sleep studies can be done at night.
