Why Sleep Matters

​Sleep is not just rest—it’s essential for your body and mind to heal, regulate, and function optimally. Poor sleep can affect your immune system, hormones, weight, mental health, and even increase your risk for heart disease, stroke, and diabetes. Chronic sleep issues can silently chip away at your quality of life and overall health.

 

We believe quality sleep is the foundation of good health. That’s why we take a comprehensive, personalized approach to uncover the root causes of your sleep problems and guide you toward lasting solutions.

Polysomnography

A polysomnography, or PSG, is an overnight sleep study conducted in a specialized lab. It comprehensively monitors your sleep, recording brain waves, eye movements, breathing, heart rate, and muscle activity. This allows us to accurately diagnose a wide range of sleep disorders.

Home Sleep Study (HSAT)

A home sleep study is a convenient option for diagnosing certain sleep disorders, such as sleep apnea. You'll use a portable device to monitor your breathing and oxygen levels while you sleep in your own bed. We'll then analyze the data to determine if you have a sleep-related breathing problem.

MSLT

The Multiple Sleep Latency Test, or MSLT, is a daytime study used to measure how quickly you fall asleep. It's often used to diagnose conditions like narcolepsy and excessive daytime sleepiness. During the test, you'll take several scheduled naps throughout the day, and we'll record how long it takes you to fall asleep.
