CINCINNATI - Doctors say insufficient sleep may be linked to heart disease.
A study published in the Journal of Sleep found those who slept fewer than seven hours a night were at increased risk of heart disease.
The study cites women under 60 in the highest risk group. Researchers say women under 60 who sleep five hours or fewer have twice the risk for developing heart disease.
Chronic sleep deprivation can also increase the risk of obesity, high blood pressure, heart attack, diabetes and depression.
