This test is conducted during the day and usually follows immediately after a routine study. You get up at your usual time, but no later than 7:30 am, get dressed and have breakfast.

At around 9:00 - 9:30 am you lie down in a quiet dark room for twenty minutes to see whether or not you fall asleep. After twenty minutes you get up and read or do some work until the next nap which is at around 11:00 - 11:30 am. There are at least four naps finishing at around 3:30 pm.

During the test you are not allowed to have any caffeine as this will affect your sleep. This means no tea, coffee, or chocolate!

What's involved in a sleep study?

The patient comes to the hospital at 8:30 - 9:00 pm at night of the study and leaves the following morning when the study is complete, at about 5:30 - 6:00 am.

On the day of your sleep study, avoid caffeine (coffee, tea, cola, chocolate) after 2.00 pm and try not to nap. Before coming to sleep centre, wash and dry your hair, and not apply hair sprays or oil.

The sleep study consists of a non-invasive test called a polysomnogram. This records a variety of body functions during sleep such as electrical activity of the brain, sleep pattern, breathing, oxygen levels, heart rate and rhythm, and muscle tone. The sleep technologist will connect the patient to the monitoring equipment via a series of stick-on electrode patches. The wires are long enough so that you can sleep in any position you wish. Once the study is complete, the test data is reviewed and "scored" by a specialist and relevant recommendations are made.

What is a Sleep study? How do I go about it?

A sleep study (also called a polysomnogram) is a test that records your physical state during various stages of sleep and wakefulness. It provides data that are essential in evaluating sleep and sleep-related complaints, such as identifying sleep stages, body position, blood oxygen levels, respiratory events, muscle tone, heart rate, amount of snoring and general sleep behavior.

You need to make an appointment for the study. The test is conducted at night.It is advisable to meet with a sleep specialist, who will go over your medical and sleep history.

After your arrive at the sleep center, you may be asked to complete a questionnaire on your symptoms and asked to change into your night clothes. The technician will connect you to a few sensors that will record your brain waves, eyemovements, and muscle movements throughout the night. A microphone attached to your neck records snoring, and two belt-like straps around the chest and lower abdomen monitor muscle movement during breathing.

When everything is working properly, the lights will be turned off and you can go to sleep. You will be awakened in the morning and the electrodes will be removed. Since they are applied with water-soluble glue or tape, removal isn't painful.
