A sleep study typically takes one night.
However, in some cases, your doctor might recommend a two-night sleep study. This is usually done to determine if your sleep problems are related to a specific event or condition. For example, if you have a sleep disorder that only occurs during certain times of the week, a two-night study can help your doctor get a more complete picture of your sleep patterns.
The number of nights you spend in a sleep study will depend on the type of study, the specific sleep disorder being investigated, and your individual needs.
Here are some examples of sleep studies and their durations:
-
Polysomnography (PSG): This is the most common type of sleep study. It usually takes one night.
-
Multiple Sleep Latency Test (MSLT): This test measures how quickly you fall asleep during the day. It is usually done after a PSG and typically takes one to two hours.
-
Maintenance of Wakefulness Test (MWT): This test measures your ability to stay awake during the day. It usually takes one to two hours.
Your doctor will discuss the specific type of sleep study that is right for you and how long it will take.
