Not getting enough sleep could double your chances of developing a condition linked to heart disease.
Less than six hours of sleep may raise the risk of metabolic syndrome. It's a set of symptoms including high cholesterol, increased blood pressure, weight gain and unstable blood sugar. The syndrome is considered an early warning of diabetes and heart disease. In addition, sleep deprivation can affect the balance of hormones that control appetite and the feeling of fullness.
Two new studies in the journal "Sleep" further bolster other research showing lack of sleep can hurt the heart, especially in women.
