Sleeping more than 9 hours a night or taking long midday naps were each associated with increased risk of incident stroke in a large, prospective cohort study.
Compared with 7 to 8 hours of sleep, 9 or more hours increased the risk of stroke by 23% (HR 1.23; 95% CI 1.07–1.41), while 6 hours of sleep had no significant effect on stroke risk, reported Xiaomin Zhang, MD, PhD, of Huazhong University of Science and Technology in Wuhan, China, and colleagues in Neurology. A regular midday nap lasting more than 90 minutes also boosted stroke risk by 25% (HR 1.25; 95% 1.03–1.53) compared with napping for a half-hour or less.
