Occasional Daytime Napping Healthy for Heart, Reveals Study


According to a new study, occasional daytime nap once or twice in a week is good for heart as it reduces the risks of heart attacks or strokes. The research was conducted at the University Hospital of Lausanne, Switzerland, where a group of scientist studied the connection between the frequency and the duration of napping during the day and the risk of fatal and non-fatal cardiovascular disease complications associated with it.

During the study, the researchers studied 3,462 people aged between 35 and 75 years for five years to come to an inference that those who were occasionally involved in daytime napping, around once or twice a week, for a duration between five minutes to an hour, were reportedly 48 percent less likely to suffer a heart attack, stroke or heart failure against those who do not take nap during the day at all.

However, no such association was found for greater frequency or longer duration of naps, revealed the study, which was published in the Heart, a British Cardiovascular Society. The researchers observed volunteers between 35 and 75 of age, who were engaged between 2003 and 2006 for the CoLaus study.

The participants were first checked between 2009 and 2012 in which the detailed information of their sleep and nap patterns were noted. Following the study, their health was afterwards examined for an average of 5 years.

The research found that those who are frequent nappers were mostly the older, smokers, weigh more and slept for long duration than those who said they did not take a nap at all. Also during the observation period, the researchers found that there were 155 fatal and non-fatal cardiovascular disease episodes. Occasional napping, once to twice weekly, was associated with almost reducing the chances of attack/stroke/heart failure risk to almost half up to 48% against those who didn’t nap at all.

Moreover, in an editorial associated to the study, Drs Yue Leng and Kristine Yaffe, of the University of California at San Francisco, USA, threw lights that research was affected by a gold standard for defining and measuring naps. According to them, the research is still premature to come to any firm conclusion on the relationship between napping and maintaining ideal heart health.

However, they also suggested that though the physiological pathways relating daytime napping to cardiovascular disease risk is unclear exactly, the research adds to the implications of napping, and advocates that it might not only be the duration, but the frequency of sleep that also matters.
