Daytime nap once a week lowers risk of heart attack and stroke

"It's often hard to untangle what is cause and effect, especially when some serious conditions, such as coronary heart disease, can be largely symptom-free for decades prior to a critical complication such as a heart attack", he told the Science Media Centre (SMC) in London.

A study published Monday in the journal Heart found that occasional napping was associated with a lower risk of heart attack, stroke and heart failure, compared to those who didn't nap at all.

Scientists from the University Medical center of Lausanne, Switzerland examined the association among napping frequency and length and the chance of deadly and non-deadly cardiovascular disorder issues.

"The ogle is of hobby and has promising results with potentially famous public health implications if the outcomes could well moreover be confirmed and clarified".

This does not mean physicians should start writing prescriptions to nap for optimal heart health, mainly because there's no way to know what "dosage" is best.

Dr. Martha Gulati, a cardiologist who is editor-in-chief of CardioSmart.org, the American College of Cardiology's patient website, said it makes sense that frequent napping could be a red flag for health problems.

Their first evaluate-up took station between 2009 and 2012, when files on their sleep and nap patterns in the old week turn out to be once quiet.

Over half of the participants (58%) said that they didn't nap in the previous week, 19% said they took one to two naps, 12% reported taking between three and five, while a very-well-rested 11% said they took between six and seven naps in the previous week.

Naveed Sattar, Professor of Metabolic Medicine at the University of Glasgow, said that while the study was "somewhat interesting", it seems that those who nap once or twice a week have healthier or organized lifestyles, but that those who napped daily were likely to be more sick.

Over the course of the study there were 155 fatal and non-fatal cardiovascular disease events.

'We also know that treating high blood pressure and managing your cholesterol can reduce your risk of life-threatening heart and circulatory diseases'.

The only factors that influenced this link were older age (65+) and severe sleep apnea.

Frequent naps initially appeared to increase a person's heart risk by 67%, but that disappeared after accounting for other risk factors, the study authors noted.

The study relied on personally-reported information and shouldn't be used to establish a cause-effect relationship, the team explains.

A study published in February suggested that people who catch up on missed sleep during the week by napping on weekends tend to snack more, increasing their risk for excess weight gain. Research in this area is further hampered by the absence of a clear standard for defining and measuring naps.

Although napping once or twice weekly was found to have nearly halved the risk of the disease in comparison to those who never napped, the experts also found that napping duration had no impact on heart attack or stroke risk.
