The Hidden Link Between Depression and Sleep Apnea
By: Jennifer Stodden PA-C
Most people do not realize that depression and sleep apnea often go hand in hand. Many people in our community struggle with fatigue, low mood, and poor sleep-often blaming it on stress or aging. But in some cases, the cause may be sleep apnea. This is a condition where breathing repeatedly stops during sleep. It has been estimated that 22% of men and 17% of women suffer from sleep apnea. Not only does this condition increase the risk of having high blood pressure, heart disease, stroke and diabetes, it can also affect mental health.
When sleep is constantly interrupted, the body never fully recharges. Over time, this can contribute to many physical problems, but also cause sadness, irritability, and lack of motivation-symptoms that look a lot like depression. Likewise, people being treated for depression sometimes find that their mood doesn’t fully improve until their sleep problems are addressed.
The encouraging news is that both depression and sleep apnea are treatable. Simple testing, like in home sleep studies, can diagnose sleep apnea. CPAP, Continuous Positive Air Pressure, is one way of treating sleep apnea. CPAP provides continuous air pressure that keeps the airway open when you sleep, preventing breathing interruptions and allowing your brain to rest. Newer CPAP machines are quiet and there are many different masks to fit each individual patient. Other treatments such as nasal dilators, mouth guards, and palate expanders have been shown to be effective as well.
If you or someone you love struggles with low mood, lack of motivation, daytime sleepiness, or restless nights, talk with your health care provider. A simple sleep study could be the first step toward better mental and physical health.
