Impact of daytime napping on heart health

Could napping once or twice a week lower your risk of heart attack and stroke?

Could napping once or twice a week lower your risk of heart attack and stroke?

"This would then explain the differential risks", Sattar told the SMC.

Researchers from the University Hospital of Lausanne, Switzerland studied the association between napping frequency and duration and the risk of fatal and non-fatal cardiovascular disease complications.

People who nap once or twice per week have a lower risk of incident CVD events.

Occasional napping - once to twice weekly - was associated with an nearly halving of attack/stroke/heart failure risk (48 per cent) compared with
those who did not nap at all.

Meanwhile, the American Academy of Sleep Medicine recommends most adults get at least seven hours of shuteye a night for a variety of health benefits. The participants were part of CoLaus - a Swiss population-based cohort between 2009 and 2017.

Their health was later monitored for an average of five years.

In a connected publication, Drs Yue Leng and Kristine Yaffe, of the University of California at San Francisco, USA, note that investigation into snoozing is unsafe due to there being no best quality level for characterizing and estimating rests, making it untimely to finish up on the fittingness of resting for keeping up ideal heart wellbeing. They categorized napping frequency as, "non-nappers, 1-2 naps, 3-5 naps and 6-7 naps during the previous week".

Despite the results, senior cardiac nurse for the British Heart Foundation Vanessa Smith, has said more research is needed before we can prove napping has any lasting benefits. The team also assessed sleep duration using the Pittsburgh Sleep Quality Index and day time sleepiness was assessed using the Epworth sleepiness scale.

A new review has found that a daytime nap taken when or two times a week could reduced the hazard of coronary heart assaults or strokes.

"What is the timing, duration and frequency of the naps?"

For those who do enjoy a bit of daytime snoozing, the signs continue to be encouraging.

About three in five said they don't nap.

Although interesting, the study doesn't necessarily provide the conclusive proof you might need to lobby your employer for a nap room.

'We also know that treating high blood pressure and managing your cholesterol can reduce your risk of life-threatening heart and circulatory diseases'. Only older age (65+) and severe sleep apnoea affected it.

In a bid to examine these issues, they looked at the association between napping frequency and the length of the nap in relation to the risk of fatal and non-fatal heart attack, stroke, or heart failure, among 3,462 randomly selected residents aged 35 to 75. But no such association emerged for either greater frequency or duration of naps.

And while there was originally a 67 percent increased risk of a cardiovascular disease event in the frequent napper contingent, this pretty much disappeared to nil when other factors (such as age, educational status, BMI, and various health conditions) were taken into consideration.

"While it remains premature to conclude on the appropriateness of napping for maintaining optimal heart health, the findings. offer some reassurance that the answer is probably more than a simple "yes" or "no", and that we have much more to learn about napping", states the editorial.

Sleep deprivation also drives up the risk for obesity, a known risk factor for heart disease.
