Sleeping too little or even too much has been associated with several disease conditions including metabolic syndrome, which predisposes a person to develop diabetes, stroke and heart disease, reports News Medical.

The findings of the study titled, “Association between sleep duration and metabolic syndrome: a cross-sectional study,” was published in the latest issue of the journal BMC Public Health.

For their study, a team of researchers from South Korea at the Seoul National University College of Medicine looked at the association between duration of sleep and metabolic syndrome. Metabolic syndrome is typically a combination of several conditions such as excessive fat around the waist, raised blood sugar, raised blood pressure and raised levels of triglycerides and cholesterol. The team of researchers obtained sleep as well as health parameters data from a large population of men and women from the Health Examinees (HEXA) study.
