sleep studies

sleep studies are a series of tests that help evaluate what happens to the body during sleep. they can help diagnose sleep disorders, which include sleep-disruptive behaviours (such as sleepwalking), sleep apnea, daytime sleepiness, and insomnia.

sleep studies include:

polysomnography, which records a variety of body functions during sleep, including electrical activity of the brain, eye movement, muscle activity, heart rate, breathing, air flow through the nose and mouth, and blood oxygen levels.
multiple sleep latency test, which measures how long it takes the person to fall asleep during the course of a day.
multiple wake test, which measures the person's ability to stay awake during a designated wakeful time.

sleep studies usually are done in a sleep lab. but sometimes they can be done with portable equipment you use at home.
