Researchers have found that sleeping for long periods may be linked to an increased risk of premature death, with people who sleep more than 9 hours a night recording higher death rates compared to those who sleep between 7 and 8 hours.
Taiwanese researchers tracked the sleep habits of more than 3,000 people over 30 years and found that the lowest mortality rate was recorded among people who slept seven to eight hours a night, at a rate of 10.57 deaths per 1,000 people.
The rate rose to 10.97 cases among those who sleep less than six hours, and to 11.27 cases among those who sleep more than nine hours.
The study did not find definitive reasons to explain the link between long sleep and an increased risk of death, but the researchers noted that people who sleep longer may be more prone to high blood pressure and inflammation, two factors that are linked to a number of health problems, including heart disease and strokes.
They also pointed out that excessive sleep may affect the body's biological clock, hormone regulation, and the efficiency of the immune system.
The researchers said that measuring sleep duration could become part of routine medical checkups, to help identify people most at risk of health problems.
Excessive sleep is also linked, according to previous studies, to a number of health problems, including heart disease, type 2 diabetes, obesity and memory impairment.
Adults are generally advised to get between seven and nine hours of sleep each night.
The study was published in the Journal of Sleep Research.
