If you often suffer from excessive daytime sleepiness, experience abnormal behaviors during sleep or have difficulty getting to or staying asleep, your doctor may refer you for a sleep study to further look at your symptoms. A sleep study can track how you sleep and how your body behaves during rest.

With locations throughout the Greater Houston area, Memorial Hermann Sleep Centers offers adults and children convenient access to sleep studies. Sleep study results are sent to your referring physician to evaluate and provide a treatment plan.

A physician's order is required to undergo a sleep study. If you need to find a doctor, click here:

If you have a physician’s referral, please call one of our Memorial Hermann Sleep Centers to schedule a sleep study.

For Physicians

To schedule a study for a patient, fax the following to your preferred Memorial Hermann Sleep Center:

  • Physician order for the study
  • Patient's demographic sheet including address, phone number, Social Security number and date of birth
  • Copy of patient's insurance card (both sides)
  • Medical history and physical results (or physician's office visit notes)

How to Prepare for a Sleep Study

When you arrive for your sleep study, you'll be shown to your private room, and test preparation will begin shortly afterward. The test is painless and begins with the attachment of electrodes to your head, chin, chest and legs, which takes about 45 minutes. You'll then be allowed to relax in your room before bedtime.

Each single patient room is equipped with a comfortable queen-size bed with a Tempur-Pedic mattress. You may bring reading materials to the sleep study, or you can watch TV in your room. You’re also welcome to bring a family member, but they will be asked to leave before the beginning of the test.

You will not be served dinner at the Center, so please eat a good meal before arriving (try not to eat anything unusual) and avoid caffeine and alcohol on the day of your study. If you need to be at work the morning after testing, inform the technologist as soon as you arrive, to allow him or her time to take the steps necessary to ensure you are able to leave on time.

For your overnight stay, please bring the following:

  • Personal toiletry items (towels and soap will be provided)
  • A robe, pajamas, gown or shorts
  • Any medications you take at night or in the morning
  • A favorite pillow or blanket (if you prefer)

Do not take any optional medications such as sleeping pills, antihistamines or tranquilizers that you're not required to take on a daily basis. If you're uncertain about which medications to take, check with your doctor.


Many health insurance companies cover the cost of testing for sleep disorders and often pay for the equipment necessary to prevent and treat any diagnosed disorders. For details about your coverage, check with your insurance company.


If you need to cancel or change the time of your sleep study, please notify the Sleep Disorders Center at least 24 hours before your appointment. There are a number of people waiting to schedule a sleep study, so if your appointment isn’t confirmed 24 hours in advance, we may need to reschedule you for the next available opening.
