A new study has shown that taking long naps during the day is associated with an increased risk for metabolic syndrome, which can also boost your risk of type 2 diabetes and heart disease. Metabolic syndrome includes conditions like high blood pressure, high blood sugar, and high cholesterol.
Japanese researchers analyzed data from over 307,000 people and found that those who napped for more than 90 minutes each day were at an increased risk of metabolic syndrome by about 50%. Daytime sleepiness also increased the risk. However, the same findings were not indicated for people who napped for 40 minutes or less.
These findings were published in HealthDay News on March 24, 2016.
