Researchers followed 3462 people, ages 35 to 75, for 5.3 years and found that those who nap once or twice a week had a much lower risk of heart disease, while those who napped more frequently than twice a week had the same risk for heart disease as those who did not nap. They explained this strange result by showing that many of the frequent daily nappers are at increased risk for heart disease because they were more likely to be older, male, cigarette smokers and/or obese. They were also likely to sleep much longer at night. When they removed these people who were at high risk for heart attacks from their data, there was no increased risk for heart attacks in those who napped more than twice a week (Heart, Dec, 2019;105(23):1768-1769). Conflicting Studies on Napping and Heart Attack Risk The frequency of daytime napping increases with age, and …
