The words “to much sleep” or “dangerous nap” isn’t really something you would ever expect to say. Let’s be honest, the majority of people don’t get anywhere near enough sleep and naps, well, that’s a fairy tale in most people’s day to day lives. But in a new study set to be presented at the American College of Cardiology 65th Annual Scientific Session, naps and their length are taken into observation regarding overall human health. The analysis included data from 21 different observational studies that involving over 300,000 subjects, in an attempt to tie naps and daytime sleepiness to a greater prevalence of type-2 diabetes and heart disease.

The test subjects were all asked a series of questions in order to report their daytime sleepiness.  The answers to the series of questions were used to evaluate the participant’s history of metabolic syndrome. Obesity, and type-2 diabetes. The results of the study showed a connection between the amount of time spent napping and metabolic syndrome risk. It was shown that people who spent less than 40-minutes napping at a time, did not show any increased risk of metabolic syndrome. However, those who napped for 40-minutes or longer saw an increased risk in their chances of metabolic syndrome. Napping for 90-minutes showed an increased risk by as much as 50 percent, being overly tired during the day showed a similar 50 percent increase in risk.

Despite the close relationship between obesity, metabolic syndrome, diabetes; the study did not show an increased risk of obesity. All of the studies evidence showed a slight decrease in the risk factors of subjects who napped for less than 30-minutes a day. The National Sleep Foundation advocates that people’s naps should be between 20 and 30 minutes a day in order to improve alertness without remaining groggy afterwards. However, the research all showed that more studies still need to be conducted in order to fully understand the connection between taking lengthy naps and metabolic syndrome.

It is believed that future research may help physicians track patience nap habits in order to predict their other health problems, such as those related to metabolic syndrome. Though the data from the study was derived from more than 300,000 participants, it may not necessarily be a good representation of the world population as a whole.  All of the information regarding the study and physicians can be found through.
