Explore Sleep Studies
Before a sleep study, your doctor may ask you about your sleep habits and whether you feel well rested and alert during the day.
Your doctor also may ask you to keep a sleep diary. You'll record information such as when you went to bed, when you woke up, how many times you woke up during the night, and more.
You can find a sample sleep diary in the National Heart, Lung, and Blood Institute's "Your Guide to Healthy Sleep."
Depending on what type of sleep study you're having, you may need to bring:
Your doctor may advise you to stop or limit the use of tobacco, caffeine, and other stimulants before having a sleep study.
Your doctor also may ask whether you're taking any medicines. Make sure you tell your doctor about all of the medicines you're taking, including over-the-counter products. Some medicines can affect the sleep study results.
Your doctor also may ask about any allergies you have.
You should try to sleep well for 2 nights before having a sleep study. If you're being tested as a requirement for a transportation- or safety-related job, you might be asked to take a drug-screening test.
If you're going to have a home-based sleep test with a portable monitor, you'll need to visit a sleep center or your doctor's office to pick up the equipment. Your doctor or a technician will show you how to use the equipment.
