SEOUL, June 13:
Sleeping for over ten hours or less than six hours a day is likely to cause metabolic syndrome – a cluster of conditions that increase the risk of heart disease, stroke and diabetes, a study has found. Researchers at Seoul National University in South Korea found that compared to individuals who slept six to seven hours per day, men who slept fewer than six hours were more likely to have metabolic syndrome and higher waist circumference. Women who slept fewer than six hours were more likely to have higher waist circumference.
Sleeping more than ten hours per day was associated with metabolic syndrome and increased levels of triglycerides in men, and with metabolic syndrome, higher waist circumference, higher levels of triglycerides and blood sugar, as well as low levels of ‘good’ cholesterol (HDL-C) in women.
