A sleep test, or sleep study, is termed polysomnography. This test monitors your sleep cycle to identify why and when your sleep cycle is disrupted. Polysomnography also helps chalk out your treatment plan once you are diagnosed with sleep disorder.
Polysomnography records, analyses, and interprets multiple physiologic signals collected simultaneously. The physiologic signals include brain waves (EEG), heart rate (ECG), breathing, oxygen level in blood, and eye and leg movements.

You will be asked to come in at least two hours before your bedtime. You can bring your personal things related to sleep, for example, your own pyjamas, books, music and such things. After you get ready for the bed, the technician will attach sensors on your scalp, temples, chest and legs with a mild adhesive. The sensors are connected to the computer with wires. The wires are long enough to allow for normal movements in the bed. A clip is attached to the finger to monitor the blood oxygen levels. Read more about 6 ways to use nutmeg for a good night s sleep
The measurements are recorded in the form of a continuous graph. The technician will monitor your sleep throughout the night and assist you if you require any help.
