Polysomnography, also called a sleep study, is a test used to diagnose sleep disorders. Polysomnography records your brain waves, the oxygen level in your blood, heart rate and breathing, as well as eye and leg movements during the study.
Polysomnography is usually done at a sleep disorders unit within a hospital or at a sleep center. The test records your nighttime sleep patterns. Polysomnography is occasionally done during the day to accommodate shift workers who habitually sleep during the day.
In addition to helping diagnose sleep disorders, polysomnography may be used to help adjust your treatment plan if you’ve already been diagnosed with a sleep disorder.
Important Things to Know About Sleep Studies
- A sleep study is done to look at your sleep. Your
doctor will be able to work out if you have a sleep
problem and, if so, what it is.
- The sleep study can be done either at home or by
staying overnight in a sleep centre.
- Together, you and your doctor will decide where
the sleep study should be done
- It lasts one night. During this time you will wear
leads to record information on how you sleep.
- If you think that you need to do a sleep study, talk
to your doctor about a referral.

What do I need to do?
PRIOR TO the day of your study:
- Notify the sleep Centre if you have any specific needs as soon as possible (see below)
**If you need to cancel your sleep study please call 2 business days prior to your test date to avoid a cancellation fee. **
Day of your study:
- Eat Supper before you arrive at the Sleep Study Centre.
- Do not drink any caffeine after 12:00 Noon. This includes: coffee, tea, chocolate, cocoa, and soda. You may drink caffeine-free sodas and/or decaffeinated coffee.
- Do not drink any alcohol 12 hours before your sleep study, unless otherwise directed by your physician.
- Wash and dry your hair and face before the study.
- Men: If you have a beard, it will not be a problem. If you are normally clean shaven, please shave before you come to the Sleep Health Centre.
- Please do not use any conditioner, gel, mousse, hairspray, or body lotions before your test.
**To cancel or reschedule**
- If you need to cancel your appointment, please call the Sleep Centre as soon as possible so that someone else may take your place. A cancellation fee of Rs.2000/- may apply if you do not cancel at least 36 hours prior to your study. That means for a night-time sleep study scheduled at 7:30 P.M., you will need to cancel by 7:30 A.M. the day before your study. This policy is in place because, for your study, we have assigned a highly trained technologist to be present for a total of 12 hours. It is very costly to our organization if we have to send this person home. In addition, there are a number of individuals who have severe sleep disorders, and if you cancel, this is a spot we could have used for individual.
- If you are not at the Sleep Health Centre by 10:00 P.M. on the night of your appointment, and have not notified us, you may be cancelled and another patient will take your place.
