Taking a daytime nap once or twice a week may halve the risk of cardiovascular events, such as heart attacks, strokes, and heart failure.
New research suggests that napping during the day could protect heart health, after all.
This is the main takeaway of an observational study appearing in the BMJ journal Heart.
Nadine Häusler, Ph.D., from the department of internal medicine at Lausanne University Hospital, in Switzerland, is the first author of the study.
As Häusler and colleagues explain in their paper, much controversy has surrounded the relationship between daytime napping and cardiovascular health.
Some previous studies, referenced by the authors, have found a lower risk of coronary heart disease among daytime nappers, while others have found a higher risk of cardiac events or cardiovascular mortality among those who regularly nap during the day.
