Once or twice weekly daytime nap linked to lower heart attack/stroke risk

A daytime nap taken once or twice a week may lower the risk of having a heart attack/stroke, finds research published online in the journal Heart. But no such association emerged for either greater frequency or duration of naps.

The impact of napping on heart health has been hotly contested. Many of the published studies on the topic have failed to consider napping frequency, or focused purely on cardiovascular disease deaths, or compared regular nappers with those not opting for a mini siesta, say the researchers.

In a bid to try and address these issues, they looked at the association between napping frequency and average nap duration and the risk of fatal and non-fatal cardiovascular disease ‘events,’ such as heart attack, stroke, or heart failure, among 3462 randomly selected residents of Lausanne, Switzerland.
