Sleep plays a vital role in maintaining physical and mental health. However, many people struggle with poor sleep without understanding the underlying cause. Persistent snoring, daytime fatigue, morning headaches, or disturbed sleep may indicate an undiagnosed sleep disorder. In such cases, a sleep study is often recommended by a sleep disease specialist to identify the exact problem.
If you have been advised to undergo a sleep study, understanding the process can help you feel more comfortable and prepared.

What is a sleep study?
A sleep study test, also known as polysomnography, is a non-invasive test that monitors your sleep patterns and breathing during the night. It helps diagnose various sleep disorders by recording important body functions while you sleep.
During an overnight sleep study, several parameters are recorded, including:
- Breathing patterns
- Oxygen levels
- Heart rate
- Brain activity
- Body movements
- Snoring patterns
The test is conducted overnight at a specialised sleep centre in Salem under the supervision of trained professionals and reviewed by a sleep physician in Salem.
