Is Sleep the Key to Better Heart Health?
Maintaining a healthy heart is more than just eating right and exercising. Did you know that too little – or too much – sleep affects your heart, too?
Studies show that not getting enough sleep or getting poor-quality sleep on a regular basis increases the risk of high blood pressure, heart disease and other medical conditions, like stroke, obesity and diabetes.
More than 40 million people in the United States suffer from chronic sleep problems and 60 million additional adults are plagued by insomnia. Add another 18 million Americans who have sleep apnea and you’ll see that sleep deprivation is a major issue in the US. Too little sleep is defined as less than six hours of sleep each night. “Sleep disorders have many negative effects on the body, and a significant impact on heart health,” said Shelby McNinch, BS, MS, RN, with the cardiac rehab team at Carolinas HealthCare System’s Sanger Heart & Vascular Institute.
Sleeping too little is bad for overall health, but sleeping too much may also be dangerous. It’s also associated with a higher risk of heart disease and obesity, diabetes and depression. Too much sleep is often defined as nine or more hours of sleep each night.
“Sleep is thought to give your heart its much-needed rest,” said McNinch. “It keeps your vascular system in shape and gives your whole body time to make repairs from damage caused by things like stress, which also contributes to cardiovascular disease.” Sleep apnea is a serious condition that affects both your sleep and health. While you are sleeping your throat becomes blocked. This causes you to stop breathing for short periods of time. In order for you to breathe, your body will wake up briefly. This cycle happens repeatedly throughout the night and can cause problems such as feeling tired during the day, and having issues with memory and concentration. Even more seriously, sleep apnea can cause other problems such as heart disease, high blood pressure and stroke. Snoring is an indicator that you might have sleep apnea. It is important to speak with your physician if you snore.
