Wash and dry your hair on the day of your sleep study. Do not use any hair products, such as gels, hairsprays or heavy conditioners, because these may prevent the electrodes from sticking to your scalp. Ask your doctor, or call the sleep laboratory to ask if you need to remove nail polish and/or artificial nails. The oximeter that is placed on your finger to monitor blood oxygen levels reads this information through the nail. Dark or red nail polish should generally be removed.

You will be notified in advance if you should alter your medications on the day of the test. Do not drink any caffeinated beverages after noon on the day of your study.
