To this conclusion came the researchers from the US Centers for Disease Control and Prevention.

In their opinion, adults who sleep too much or too little may be more prone to heart attacks and strokes. This is reported by the radio "Vesti FM".

For the study used medical data more than 12 thousand people aged 30 to 74 years. None of them at the time of the commencement of work had cardiac insufficiency or strokes. Participants were divided into several groups.

Some reported that they slept for five or less hours, others talked about six hours, others - about seven, the fourth - about eight and the fifth slept for nine or more hours.

It turned out that people who slept for an hour more or less than needed had an average heart rate of 4.5 years older than normal. At night sleep lasting five hours or less, this figure was even higher - more than 5 years. The least heart is aged with the recommended duration of sleep at 7 hours a day.
