Their responses revealed that, on average, those who slept fewer than six and more than ten hours were at higher risk of metabolic syndrome than those who slept between six to seven hours a day.
Men who slept fewer than six hours (11 percent of the sample) were more likely to have metabolic syndrome and a larger waist. Women who slept fewer than six hours (13 percent of the sample) were more likely to have a larger waist.
Men who slept more than ten hours per day (1.5 percent of sample) were linked to metabolic syndrome and higher than normal levels of triglycerides. Women who slept too much (1.7 percent of sample) carried a risk of higher triglycerides, metabolic syndrome, higher waist circumference, and blood sugar as well as low levels of “good” cholesterol HDL-C.
