A visit to a sleep disorders facility for a sleep study is likely to be an experience for you. A sleep study, or polysomnogram. is a recording that includes measurements used to identify different sleep stages and classify various sleep problems.
During sleep testing, the activities that go on in your body during sleep (brain waves, muscle movements, eye movements, breathing, snoring, heart rate and leg movements) are monitored by small electrodes applied to the head and skin with adhesive. Flexible elastic belts around your chest and abdomen measure your breathing.
