Sleep disorders cause many troubling symptoms that can affect one’s mood, energy level, and overall health. Accurate diagnosis is necessary to enable effective treatment for sleep disorders. A sleep study provides valuable insight into the causes of a person’s symptoms including which, if any, sleep disorder is present. Sleep studies are also used in people diagnosed with sleep disorders to monitor their response to treatment.

Your doctor will determine whether you need your sleep test at a sleep center or if you can do it at home with a portable device. Sleep tests at a sleep center usually last overnight. Removable sensors will be placed on your scalp, face, eyelids, chest, limbs, and a finger. These sensors record your brain waves, heart rate, breathing effort and rate, oxygen levels, and muscle movements before, during, and after sleep. There is a small risk of irritation from the sensors, but this will go away after they are removed.
