Harvard’s Health Blog looks at a new study that shows a link between too much sleep and stroke risk.
Researchers publishing in the December 11, 2019, online issue of Neurology describe an analysis of stroke risk among nearly 32,000 adults with an average age of 62. The study’s authors compared rates of stroke with study subjects’ self-reported sleep habits.
Their findings were surprising (at least to me) and included:
Those who reported sleeping nine or more hours each night had a 23% higher risk of stroke than those sleeping less than eight hours each night.
Stroke risk was 25% higher among those who took midday naps for at least 90 minutes compared with those napping for less than 30 minutes.
