Daytime Sleepiness Linked to Risk of Metabolic Syndrome
Metabolic syndrome is characterized by increased blood pressure, high blood sugar, excess body fat around the waist, and abnormal cholesterol or triglyceride levels. And it greatly increases your risk of heart disease, stroke and diabetes.
This makes the findings of a new study especially important. The results will be presented at the American College of Cardiology’s 65th Annual Scientific Session in April.
The study analyzed data from 21 studies and involved over 307,000 people who self-reported their daytime tiredness and napping habits.
Then, the researchers compared the responses with the participants’ history of metabolic syndrome, type 2 diabetes and obesity.
The analysis revealed that…
- Subjects who napped for more than 40 minutes during the day showed a sharp increase in the risk of metabolic syndrome.
- Napping for 90 minutes appeared to increase the risk by as much as 50 percent. So did excessive daytime tiredness.
- There was a slight decrease in risk of metabolic syndrome when participants napped for less than 30 minutes.
Previous work by the research team shows that napping for longer than one hour corresponds to a 50 percent increase in type 2 diabetes.
The authors note that, because the data is self-reported, the results may not represent the world population. However, it does indicate the need for follow-up research.
Moving forward, future research should focus on “clarifying the relationship between naps and metabolic disease,” with the hope of offering a new strategy of treatment, says lead author Tomohide Yamada, MD, PhD.
