About this test

What Sleep Study (Polysomnography) involves

Sleep study, or polysomnography, is a medical test that monitors and records your body’s functions (brain waves, heart rate, breathing, oxygen levels, eye/leg movements) overnight to diagnose sleep disorders like sleep apnea, insomnia, or narcolepsy. Conducted at a sleep center, clinic, or sometimes at home, it uses sensors to track sleep patterns, helping doctors understand sleep quality and design treatment plans for better overall health.
