Sometimes I might take a short power nap during the day, but on weekends, I've taken some long naps. Not all the time, though. I do have trouble with sleeping at night. I go to bed early enough and usually fall asleep okay, but then I wake up only after about 5 hours and can't get back to sleep.
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.
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, they reported in Neurology.
What drives this connection is unclear, but "previous studies have shown that long nappers and sleepers have unfavorable changes in their cholesterol levels and increased waist circumferences, both of which are risk factors for stroke," Zhang said in a statement. Long napping and sleeping also may suggest an overall inactive lifestyle, Zhang added.
