What is polysomnography? Polysomnography is type of test that is used to study sleep by tracking biophysiological changes during the sleep cycle such as brain activity, eye movements, muscle activity, heart rhythm and breathing. According to the Bureau of Labor and Statistics, people aged 15 - 19 get the most sleep at night, nearly 10 hours while people between 44 and 54 years old get just over 8 hours of sleep. A polysomnography test would study people such as these to determine how the amount of sleep they get affects their daily life, from work to social interactions to the ability to concentrate or remember. This test would also look at how sleep affects the body at different ages and why you need more sleep when you are younger. A polysomnography test should only be administered by a trained professional, so if you want to enter this field, you will need to get polysomnography training. Career careers will polysomnography training prepare me for? Some of the careers you can enter into with polysomnography training include research and development. Many times people who work in other careers, such as physicians and technicians will get polysomnography training to increase their ability to help patients. Polysomnography tests are used by many different types of people for many reasons - to develop a new sleep aid, physical therapy and healing, to understand neurological patients or to find the best way to put a baby to sleep. Because the sleep process is such an integral part of the human existence, having polysomnographic training will help in a variety of ways that are broadly applicable.
