How can sleep apnea affect your heart and blood pressure?

Reviewed by Yoshinori Abe, MD

Internal Medicine

Sleep apnea forces your heart to work harder and raises your blood pressure, both of which can damage long-term heart health. When breathing repeatedly stops during sleep, oxygen levels drop, triggering stress responses that strain the cardiovascular system and increase the risk of hypertension, heart disease, and stroke.

If you snore loudly, wake up gasping, or feel exhausted despite a full night's rest, don't guess what's wrong. A free, instant, online symptom check can help you understand your symptoms, identify possible causes, and guide your next steps—before minor warning signs turn into serious heart problems.

Explanation

Sleep apnea is when you stop breathing for short times while you sleep. This can be bad for your heart and blood pressure.

How Sleep Apnea Affects Your Heart

Heart Strain: When you stop breathing, your heart has to work extra hard to get oxygen to your body.
Irregular Heartbeats: Sleep apnea can cause your heart to beat in a funny way, which is not healthy.

Blood Pressure

Increases Blood Pressure: Sleep apnea can make your blood pressure go up. High blood pressure is not good because it can hurt your heart and blood vessels.

Why It Matters

Having sleep apnea can make you more likely to have heart problems, like heart attacks or heart failure.
