Washington DC, Aug 3 (THAINDIAN NEWS) New research indicates all the sleep we need as humans is around seven hours, which also includes the afternoon naps and the power naps as well. The research also indicates that we could easily increase the risk of heart disease, if you sleep more or less than the magic number of hours. It ought to be mentioned that heart-related diseases are the number one cause of deaths in the United States.

People who sleep less than five hours a day, including naps are two times at risk of developing heart-related diseases such as angina, coronary heart disease, heart attack or stroke according to reports published in the “Sleep” journal by a team of medical researchers from West Virginia University.

“An additional hour or two of sleep in the morning after a period of chronic partial sleep loss has genuine benefits for continued recovery of behavioral alertness,” according to David Dinges, who is the head of the sleep and chronobiology unit at the University of Pennsylvania school of medicine.

The report also indicated that sleeping over seven hours including naps were one and half times more at risk to develop heart-related diseases, than even those who slept far less than the required seven hours. People under 60 years were three times more likely to develop heart diseases, if they slept five hours a week in relation to people who slept the required seven hours.
