A very scientific approach would be to undergo a sleep study. Called Polysomnogram (PSG), it is a safe, painless, and simple evaluation of how your body functions during sleep. It is performed by a registered sleep technician. Data is recorded while you are sleeping and later reviewed by a board-certified sleep physician. The study can provide a detailed evaluation to determine if you have a sleep disorder. If you do have a sleep disorder, it is important to be diagnosed and treated.
