Most people agree that getting the right amount of sleep is essential to feeling one’s best. According to a team of researchers in the UK who studied more than 8,000 people for 12-17 years, found that among participants who slept 6-8 hours at the start of the study, shorter sleep duration was associated with a 110% higher risk of cardiovascular mortality. Similarly among participants who slept 7-8 hours at the start of the study – increased sleep duration was associated with a 10% higher risk of non-cardiovascular mortality. The results suggest that sleeping 7-8 hours at night may be optimal for good health.
