Research links sleep to stroke risk in women

The study published in the journal of the American Heart Association found women who habitually slept more than 9 hours per night had a 60 percent higher risk of the most common form of stroke caused by blocked blood vessels in the brain. Women who slept less than six hours per night also had a 14 percent increased risk.

Researchers say it's possible the hormonal differences that influence sleep habits also alter our risk for certain diseases.
