sleep studies (polysomnography)

A sleep study, or polysomnography, is a test that records various body functions during sleep, such as brain activity, eye movements, heart rate, breathing, oxygen levels, and muscle activity. It helps diagnose sleep disorders like sleep apnea, restless legs syndrome, or narcolepsy. The test is usually done overnight in a sleep center or sometimes at home with portable equipment. Sensors are attached to your body to monitor these functions while you sleep normally. The data collected helps doctors identify specific issues affecting your sleep quality and develop appropriate treatment plans.
