You will have a lot questions in your mind when you think about the impending sleep clinic experience. In most cases, you don’t know what to do or how to behave once you are there. All you need is answers to feel relaxed and at peace. Here is what you need to know.
Why you need a sleep study
If you are having trouble sleeping, or you constantly have morning headaches, a sleep study will help you to know whether it is a sleep apnea or something else. It is the most recommended way to diagnose sleeping disorders in Canada. Many parts of the brain are involved when sleeping. Each part controls the sleeping process, from drowsiness, light sleep, deep sleep to dreaming sleep. An overnight sleep at the clinic will measure your brain waves and record the movements of your eyes and legs to quantify the amount of sleep you take at a given period. The doctor will then get a bigger picture of your sleeping patterns from the test.
Preparing for a sleep study
For effective results, you will have to change some of your habits before the sleep study test. If you love coffee and other drinks rich in caffeine, you will have to stop an afternoon or evening before the overnight study. Also, do not take alcohol that day. Try not to sleep during the day. Wash your hair thoroughly with a shampoo only? Dry your hair well and do not use sprays, oils or gels. Most of these substances affect the test because they can interfere with the sensors. You will have to pack a bag to take with you to the clinic. The bag should contain all the things you may need, including the clothes you will change the next morning. You may also need to bring your own pillow.
Tell the doctor if you are on any medication
It is imperative your doctor knows the medicines you take. You should tell him several hours before the actual test. This include both prescribed and non-prescribed drugs. The doctor should know because certain drugs can affect your sleep and the accuracy of the results. You may be required to gradually cease taking some medications in the days leading to your sleep study.
What happens during a sleep study
A technologist will lead you to a bedroom and show you the equipment that will be used. He will then put sensors on the skin of your head to record the brain waves and other vital signs. Also, he will put a clip on your finger to monitor the heart rate. The technologist will then analyze the results for several hours to come up with an accurate diagnosis. If you have abnormal results, the doctor can recommend CPAP masks or any other treatment he thinks may help.
