The Importance of Sleep For Your Health and 6 Sleep Remedies to Get More Sleep
3. Healthier Heart
When it comes to heart health, research definitely supports the need for a good snooze. Adults who regularly sleep less than six hours a night have an increased risk of heart attacks and developing high blood pressure compared to those who sleep 7 to 8 hours per night. And 7 to 8 hours might be the magic number: Recent studies have also shown an association between excessive sleep (more than 9 hours a night for adults) and cardiovascular disease.
In one study, researchers observed elevated levels of C-reactive protein—an indicator of heart disease—both in women who slept 5 or fewer hours and also (and even more markedly) in those who slept 9 or more hours. And a large Swedish study just reported this month in the European Journal of Epidemiology found an association between short sleep duration (5 hours or less per night) and increased cardiovascular events such as heart attack and stroke.
