Men: If you normally shave, please shave in the evening before you come to the lab. This will help us obtain better recordings. Patients with beards are not expected to shave. Wash your hair.

Women: Wash your hair and abstain from using hair spray. Wash your face but do not use face cream or moisturizers. Wear little or no make-up. Remove nail Polish.

What to bring when coming for a sleep study:

  • Appropriate sleepwear, something you feel comfortable in. Do not buy sleepwear for the occasion. Even sweat suits are suitable.
  • You are also encouraged to bring your own pillow if it helps you sleep.
  • Personal toiletries, (toothbrush, comb, shampoo, etc.)
