Sleep: How It Affects Your Heart

There are risk factors involved as our nightly sleep duration decreases or so it has by 1.5-2 hours per night.  15 Medical studies of 475,000 people found that short sleepers had a 48% increased risk of developing or dying from coronary heart disease (CHD) and 15% risk of heart disease.  According to the November 2011 European Heart Journal, the studies were conducted in a 7 to 25-year follow up period.  Long sleepers who slept 9 or more hours – showed a 38% increased risk of developing or dying from CHD and 65 % increased risk of stroke.

Good quality sleep helps blood pressure and heart rate go down at night as the heart slows down naturally.  If there’s no quality sleep : insulin resistance increases, heart rate stays elevated as people don’t get enough good sleep and that puts stress on the heart. Above all, shortened sleep can increase the C-reactive protein which is released with stress and inflammation – a risk factor for cardiovascular disease.
