A sleep study is a diagnostic test that records certain body functions while you sleep. This test—often called polysomnography (PSG)—may be recommended when there are concerns about sleep disorders such as snoring or obstructive sleep apnea. The purpose of the study is to collect information about how your body behaves during sleep so your physician can better understand what may be affecting your rest.
Sleep studies are typically painless and are performed while you sleep, allowing healthcare providers to observe patterns that may not be noticeable during the day. The information gathered during the study helps physicians evaluate sleep quality and identify signs of sleep-related breathing disorders.
Your physician may recommend a sleep study if you experience symptoms that suggest a possible sleep disorder. These symptoms may include:
These symptoms are sometimes associated with obstructive sleep apnea (OSA), a condition in which airflow may become partially or completely blocked during sleep. A sleep study helps determine whether breathing interruptions occur and how often they happen during the night.
Sleep studies may be conducted in a sleep laboratory or, in some cases, at home using portable monitoring equipment. The most comprehensive option is an overnight sleep lab study, where monitoring equipment records several body functions while you sleep.
Depending on the type of study, the monitoring equipment may track:
These measurements help physicians observe how your body functions during sleep and identify patterns that may indicate a sleep disorder.
If you or someone in your household notices persistent snoring, interrupted breathing during sleep, or ongoing daytime fatigue, it may be worth discussing these symptoms with a healthcare provider. An evaluation by an ENT specialist can help determine whether a sleep study or other diagnostic testing may be appropriate.
