It’s important to get your sleep. A good 7-8 hours helps you feel your best, protects you against diabetes, wards off heart disease and even burns calories. But how much sleep do you really need?
A study by researchers at the University of Birmingham School of Medicine found that those that slept more than eight hours a day—including naps—were 15 percent more likely to have metabolic syndrome than those who slept less. Metabolic syndrome is a group of risk factors, linked to obesity, which increase your chance of having heart disease and other health problems, including diabetes and stroke.
The authors of the study couldn’t say if the extra hours of sleep were the cause or the symptom of metabolic syndrome, but they suggested that “long sleepers” see health benefits from reducing the amount of sleep they get.
