Lack of Sleep Linked to Early Death

People who get less than six hours sleep per night have an increased risk of dying prematurely, researchers said.
Those who slumbered for less than that amount of time were 12 percent more likely to die early, though researchers also found a link between sleeping more than nine hours and premature death.
"If you sleep little, you can develop diabetes, obesity, hypertension, and high cholesterol," Francesco Cappuccio, who led research on the subject at Britain's University of Warwick, told AFP.
The study, conducted with the Federico II University in Naples, Italy, aggregated decade-long studies from around the world involving more than 1.3 million people, and found "unequivocal evidence of the direct link" between lack of sleep and premature death.
"We think that the relationship between little sleep and illness is due to a series of hormonal and metabolic mechanisms," Cappuccio said.
