Sleep disorders such as insomnia and sleep apnea can be connected to a host of health issues, including diabetes, high blood pressure, and obesity. Our Sleep Study allows us to identify sleep disorders so you can get the rest you need, because fortunately, most sleep disorders are treatable once they are diagnosed.

The main types of sleep are rapid eye movement (REM) and non-rapid eye movement (NREM). Normally, you alternate between these stages four or five times per night. Disruption in this cycle can make it hard to get a good night’s rest.

During the overnight Sleep Study, we track an array of vital signs including your brain activity, eye movement, electrocardiography (EKG), activity, oxygen saturation, airflow, and leg/limb movements. The test will be performed in a private room, but we ask that your family do not stay the night, unless under special circumstances.

Every effort will be made to maintain your regular routine and sleep schedule.

An estimated 1/3 of Americans suffer from some form of sleep disorder
