Older Women's Stroke Risk Linked to Sleep
Stroke Risk Higher in Women Who Sleep More Than 9 Hours or Less Than 6 Hours Per Night
Sleep and Stroke Risk continued...
Although the degree of increased risk associated with getting too much sleep was much higher than that associated with getting too little sleep, researchers say nearly twice as many women reported getting less than six hours of sleep a night (8.3%) compared with those who got nine hours or more (4.6%).
"The prevalence in women of having long sleep duration is much lower than having sleep duration less than six hours. So the overall public health impact of short sleep is probably larger than long sleep," researcher Jiu-Chiuan Chen, MD, ScD., assistant professor of epidemiology at the University of North Carolina's School of Public Health in Chapel Hill, says in a news release. "This study provides additional evidence that habitual sleep patterns in postmenopausal women could be important for determining the risk of ischemic stroke."
Chen is careful to point out that these results apply only to postmenopausal women and can't be applied to other groups.
