Sleep Lab Test in Chennai – Complete Guide to Better Sleep Health
Sleep disorders are becoming increasingly common due to stress, lifestyle, and health conditions. If you experience snoring, fatigue, or breathing issues during sleep, a sleep lab test in Chennai can help diagnose the root cause and guide effective treatment.
What is a Sleep Lab (Polysomnography) Test?
A sleep lab test, also known as Polysomnography (PSG), is a detailed overnight diagnostic test that monitors multiple body functions during sleep. It records:
- Brain activity (EEG)
- Heart rate (ECG)
- Oxygen levels (SpO2)
- Breathing patterns
- Eye and muscle movements
This test helps doctors accurately diagnose sleep disorders and plan the right treatment.

A professional sleep study can detect:

Early diagnosis prevents serious complications like heart disease and chronic fatigue.
