What is Polysomnography?

In this lifestyle, full of stress and pressure, we end up getting minimal sleep. In most cases, there is a complete lack of sleep and we are left sleep deprived. Often these conditions lead to restlessness, depression, weakness and an inability to do any activity vigorously. There is a special branch of study and medicine that is designed to test our sleep patterns and the way our body behaves when we sleep. This is called as the Polysomnography test.

Often called a sleep study, it is a test that electronically transmits and records some physical activities while you are sleeping. With this data, the doctors can identify if you have a sleep disorder and can suggest the alternative treatment as per your needs. The treatment is also given as a part of the package when you have a psychological disorder. These tests are usually given across for older people who are suffering from trouble sleeping, but with the conditions, we are facing in the day to day lives; the treatment is also suggested for the younger lot nowadays.

What are the types of sleep study tests?

There are four types of the sleep study and depending on your needs each one of them is performed.

  2. Diagnostic daytime multiple sleep latency tests (MSLT) is the second type and is used to check your sleep patterns during day time and the frequency in which you sleep across in a calm daytime environment.
  3. Two-night evaluation is a combination of sleep test that is based on your general status on one day and on the second day the same pattern would be repeated with artificially induced agents like oxygen masks, fabricators, etc.
  4. Split – night PSG with CPAP titration is the last type and can be done when you have severe sleep disorder patterns or sleep apnea. These treatments are extremely safe and if you have any concerns, you can check with your physician.

What happens during a sleep study?

A sleep disorder can occur at any stage of life and can depend on a number of situations. Hence one form of treatment may not be beneficial for all.

What are the alternatives to the treatment?

As an alternative to the treatment, you can identify what is causing you the stress and can try to minimize on your own. You can indulge in regular workouts and exercises to keep your body fit and healthy. Also, you might opt for yoga and meditations so that you can have more control over your sleep patterns.
