Seven Hours of Sleep Is Optimal for Heart Health

Sleeping for more or less than seven hours per night increases the risk for cardiovascular disease finds a study published in the journal Sleep. An analysis of the sleep habits of more than 30,000 people found that those who slept for five or fewer hours were more than twice as likely to develop CV disease than those who slept for seven hours. Increased risk for CV disease was also found for those who slept for more than nine hours per day. "Our study findings may have important clinical and public health implications, such as screening for changes in sleep duration by primary care physicians as a potential risk factor for cardiovascular disease, or initiating public health initiatives focusing on improving sleep quality and quantity," said principal investigator Anoop Shankar, MD, PhD.
