Sleep Study is also known as Polysomnography. It is used to diagnose sleep disorders in an effective manner. Polysomnography records many parameters during the Sleep Study. It Includes heart rate, breathing levels, brain wave patterns, and even the oxygen level in your blood.

Sleep Studies are mostly done in a hospital or at centers at their sleep disorder units. These sleep disorder units are made especially for Sleep disorder Checkups with the needed appropriate types of equipment. Let Us Clearly See what types of equipment are used in these centers in the later part of our Article.

As mentioned above, Sleep Studies can be done also at home. But the drawback is only limited types of equipment can be used, so as a result, we can get the report with a minimum number of parameters assessed.

Home sleep Apnea testing Uses a limited number of sensors to focus mainly on (OSA) that is, obstructive sleep Apnea.

Beginners guide

You may wonder what is Obstructive Sleep Apnea. Here is a small Description so that you can proceed with the article with a basic knowledge


                            Obstructive Sleep apnea is a Sleep Disorder. It occurs when the muscles that support breathing start to temporarily relax. As a result, the airway is narrowed or closed and breathing starts to get narrowed or totally cut off. 


So now with this Guide Knowledge, let us move to the next part with Good understanding 🙂

Why Is Sleep Study Done?

Like any other studies, Polysomnography also helps us to track data. As the name suggests sleep study helps us to keep a check on our sleep cycles and helps us know when our sleep patterns are disrupted. It also helps us to know the reason why the patterns are disrupted and at the same time solutions can also be tried with maximum positive results

So To understand Why sleep Studies are done let us Have Some Basics on the Different stages of sleep.

Normal Sleep Patterns begin with a stage called (NREM) Non-Rapid Eye Movement stage. In this stage, the eye movements are slow and minimal. Brain waves start to slow down as the times move on. This  Brain activity is measured by a type of instrument called Electroencephalography

As time passes, after 2 to 3 hours the brain activity starts to pick up and Rapid Eye movements take place. This phase is called the Rapid Eye Movement Stage. These are the two Sleep stages

So this cycle continues many times with a time period of approximately 90-100 minutes.

And here comes the role of Sleep Studies because sleep disorders disturb the REM and NREM  cycles.

Some of the main cases where doctors recommend Sleep Study are mentioned Below :

  • REM Sleep Behaviour Disorder – In this disorder people start to react or act to the dreams as they sleep.
  • Behaviors that are unusual – In sleep people do unusual behaviors like walking, running.
  • Narcolepsy – In this condition, people feel dizzier in the daytime with a punch of sudden sleep attacks.

Some other main causes are Limb movements and Sleep Apnea
