Their health was later monitored for an average of five years.
But more frequent napping provided no benefit, researchers found.
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.
Nadine Hausler, an author of the study, stated that only the over-65s who had severe sleep apnoea were still at high risk of a heart attack or stroke if they were regular nappers.More news: Watch Alex Cora’s Pregame Press Conference Ahead Of Red-Sox Yankees
In older adults, frequent naps may be a sign of an underlying problem, like Alzheimer's disease.
"This indicates the previous pattern of occasional napping is intentional and the latter of a lot more common napping very likely represents sub-clinical illness joined to poorer way of life". The naps might not be directly responsible for the variation in CVD incidents.
The observational review, which was released in Heart, the journal of the British Cardiovascular Society, uncovered that no these affiliation emerged for better frequency or duration of naps. Subjects napping as many as seven times a week disappeared in the model used by researchers.
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.
The effect of snoozing on heart wellbeing is as yet hazy. Another 12 percent took three to five. Participants who fell into that category saw their risk of experiencing a cardiovascular disease event decrease 48 percent - even when factors such as age, night-time sleep duration, and health aspects (e.g. high blood pressure) were taken into consideration.More news: Apple to launch most expensive iPhone ever in United Kingdom next week
And it did not change after factoring in excessive daytime sleepiness, depression and regularly sleeping for at least six hours a night.
Could nap frequency help explain some of the disparity in these results? "Do we count in a 5 min "dozing-off" as a nap?" wrote Yue Leng, an epidemiologist studying sleep behavior at the University of California San Francisco, in an editorial published alongside the new study.
And they conclude: "The study of napping is a challenging but also a promising field with potentially significant public health implications".
To nap or not to nap, that is the question for many exhausted Kiwis.
But they add: "While the exact physiological pathways linking daytime napping to [cardiovascular disease] risk is not clear, [this research] contributes to the ongoing debate on the health implications of napping, and suggests that it might not only be the duration, but also the frequency that matters".More news: Cristiano Ronaldo Scores 4 Goals in Portugal's Rout of Lithuania
