The hidden link between sleep and heart health

You may not think about your heart when you go to bed, but your sleep habits play a powerful role in how well it works.

A good night’s sleep does more than help you feel rested. It helps protect one of your most important organs, your heart.

Many people focus on diet and exercise to stay healthy, but often overlook sleep. When sleep suffers, your heart can suffer too. Getting enough quality rest allows your body to recover, regulate blood pressure and reduce stress on the cardiovascular system.

One of the most common sleep-related conditions is sleep apnea. Nearly 30 million Americans are estimated to have it, but many do not know they do. Sleep apnea occurs when breathing repeatedly stops and starts during sleep, reducing the amount of oxygen your body receives overnight.

Many people associate sleep apnea with loud snoring, but other warning signs include morning headaches, daytime fatigue, difficulty concentrating and waking up feeling unrefreshed. In some cases, a spouse or family member may notice pauses in breathing during the night.

Sleep apnea places stress on the cardiovascular system. When untreated, it can increase the risk of high blood pressure, irregular heart rhythms and heart disease.

Even without sleep apnea, poor sleep can take a toll on your health. When you consistently get too little sleep, your body may release stress hormones that increase blood pressure and inflammation. Over time, those changes can contribute to heart disease and other health problems.

The good news is that small changes can improve both sleep quality and heart health.

Sleep tips to support a healthy heart:

• Aim for seven to nine hours of sleep each night.
• Go to bed and wake up at the same time every day, even on weekends.
• Limit screen time for at least 30 minutes before bedtime.
• Keep your bedroom cool, dark and quiet.
• Avoid large meals, alcohol and caffeine close to bedtime.

Sleep is one of the most powerful tools we have for protecting heart health. When patients improve their sleep, we often see improvements in blood pressure, energy levels and overall wellness.

If you snore loudly, wake up tired despite spending enough time in bed or often feel fatigued during the day, do not wait to talk with your primary care provider. A simple evaluation can help determine whether a sleep disorder may be impacting you.
