What is a Sleep Study and How Does It Work

There are many things in life that we take for granted. One of those is the ability to sleep soundly through the night without interruption. For some people, this is not the case. They may suffer from a sleep disorder that disrupts their normal sleep patterns. If you think you may have a sleep disorder, or if you’re just curious about what happens during a sleep study, read on! In this article, we will discuss what is a sleep study and how it works.

What is Sleep Study?

A sleep study, also known as polysomnography (PSG), is a test that records information about your breathing and body movements during sleep. It can help diagnose disorders such as: obstructive sleep apnea (OSA), narcolepsy or restless legs syndrome(RLS). The PSG typically takes place at night in a sleep lab, where you will be hooked up to several devices that will monitor your brain waves, heart rate, blood pressure and oxygen levels.

The test typically lasts about eight hours, during which time you will be observed by a technician. You may also be asked to keep a sleep diary for one or two weeks prior to the study so that your doctor can get an idea of your normal sleep habits.

If you are found to have a sleep disorder, there may be treatments available that can help improve your quality of life. For example, if you have OSA, you may need to wear a CPAP machine while you sleep to keep your airways open.
