Polysomnography or sleep study is a test that is performed to diagnose sleep disorders. It records body functions such as breathing, brain waves and heart rate while you sleep or try to sleep.

A polysomnography is done to diagnose sleep disorders like obstructive sleep apnoea. It is done to identify if and when your sleep is disrupted and why.

Polysomnographies are typically done in a sleep lab. However, nowadays there are technologically advanced methods and equipment which allow polysomnographies to be done at home.

A polysomnography is recommended for people who present with signs and symptoms of moderate to severe obstructive sleep apnoea (where the breathing repeatedly stops and starts during sleep). It is also recommended to evaluate other sleep disorders like narcolepsy, periodic limb movement disorder, insomnia and unusual behaviours during sleep such as sleepwalking.

A polysomnography measures blood oxygen levels, heart rate, breathing pattern and records brain waves as well. Eye and leg movements are also recorded during the study.
