Sleeping habits, including the number of daytime naps, can influence the appearance and evolution of cardiovascular disease according to a recently published study.
The research explored the relationship between sleeping patterns and health in over 116,000 people from seven regions spread around the globe.
The results are quite surprising as people that tend to sleep beyond the six to eight hours recommended by scientists are more likely to develop cardiac diseases and die younger. Statistics showed that people who oversleep between two or three hours present a 5% higher risk in comparison to people that tend to follow the recommended sleeping schedule. Those that sleep for more than 9 hours reach a risk of 17% while those that sleep for more than 10 hours have a whopping 41% increased risk.
The research also notes that 9 people out every one thousand that sleep less than six hours per night will also develop a cardiac disease during their lifetime.
The leading author of the study, Chuangshi Wang, noted during an interview that the optimal sleeping schedule for adults ranges between six and eight hours per night. As the study is mainly observational, there is no concrete proof that the heart issues are caused only be sleep.
Other studies have previously suggested a link between sleeping patterns and heart conditions but in many cases the results of one study were contradicted by the results of another.
Researchers took a variety of factors like sex, age, education, smoking, alcohol consumption and others into consideration in order to provide the most accurate results possible. Daytime naps are often taken in zones like Middle East, China, Southern Asia and South America, spanning between 30 and 60 minutes. While it some cases it may lead to a higher risk the results were not significant enough to warrant additional research.
While the study offers valuable insight further research is needed before a definitive conclusion can be made.
The study has been recently published in a peer-reviewed journal.
Laura grew up in a small town in northern Quebec. She studied chemistry in college, graduated, and married her husband one month later. They were then blessed with two baby boys within the first four years of marriage. Having babies gave their family a desire to return to the old paths – to nourish their family with traditional, homegrown foods; rid their home of toxic chemicals and petroleum products; and give their boys a chance to know a simple, sustainable way of life. They are currently building a homestead from scratch on two little acres in central Texas. There’s a lot to be done to become somewhat self-sufficient, but they are debt-free and get to spend their days living this simple, good life together with their five young children. Laura is an advocate for people with disabilities.
