Not enough sleep – you could explode

Researchers found if you sleep less than six hours, or have disturbed sleep you have a 48% chance of developing or dying from heart disease, and a 15% chance of having or dying of a stroke. The study, published in the European Heart Journal, is a meta-analysis of 15 other sleep studies. A meta-anaylsis integrates a number of studies into one study. Researchers followed nearly 475,000 adults from eight countries including the United States, United Kingdom, Japan, and Israel for seven to 25 years.
