In new research conducted on more than 3,400 volunteers in Switzerland, scientists found out that daytime sleep might reduce risks of heart attack and stroke. However, too much daytime nap reduces the benefits.
The study’s results showed that it is ideal for taking one or two daytime naps per week to lower risks of cardiovascular diseases, such as heart failure, stroke, and heart attack. Also, those benefits were not present in subjects over 65 years of age.
“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,” two researchers, not involved in the research, wrote in an editorial issued in the journal Heart.
Daytime Sleep Might Reduce Risks Of Heart Attack And Stroke
However, the study was observational. That means that the researchers did not look in-depth for the reasons why daytime sleep might reduce risks of heart attack and stroke. Accordingly, the new research doesn’t establish cause and effect.
According to some experts, taking one or two daytime naps per week could mean a more organized life, and that is essential to reduce risks of cardiovascular diseases. On the other hand, the study based on self-reporting, not on observations made under specific conditions. So, the results could be biased by the subjects’ answers to researchers’ questions.
Nonetheless, the study brings some new, fascinating details on the connection between daytime sleep and heart conditions. “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,” reads the editorial published in the Heart journal.
