After an average of 5 years of follow-up, those who slept 1-2 times per week were 48 percent less likely to develop cardiovascular issues, such as heart attacks, strokes, or heart failure, than those who did not sleep at all. Those who slept 3-4 times per week had a 20 percent reduction in risk. Those who reported sleeping more than 9 hours each night were 42 percent more likely to have cardiovascular problems over time. However, when they did report sleeping longer periods, these people were less likely to suffer cardiac arrest or require a coronary artery bypass graft surgery. They also experienced fewer cases of hypertension and diabetes compared with those who didn't get enough sleep. Napping can benefit your heart health by giving your body a rest from the stresses of daily life. Research shows that sleep helps remove toxins from the body and improves cognitive function. Napping also reduces stress and aids in maintaining a healthy weight. Getting sufficient sleep is important for your physical and mental well-being. If you struggle with insomnia, make sure to talk to your doctor about whether sleep medications are right for you.
