Insomnia

Insomnia is a common sleep disorder.


If you have it, you may have trouble falling asleep, staying asleep, or both. As a result, you may get too little sleep or have poor-quality sleep.


You may not feel refreshed when you wake up.

Symptoms of insomnia include:

  • Lying awake for a long time before you fall asleep

  • Sleeping for only short periods

  • Being awake for much of the night

  • Feeling as if you haven’t slept at all

  • Waking up too early

Your doctor will diagnose insomnia based on your medical and sleep histories and a physical exam. He or she also may recommend a sleep study. 


A sleep study measures how well you sleep and how your body responds to sleep problems. Treatments include lifestyle changes, counseling, and medicines.
