People who take long naps during the day are at higher risk of developing heart disease, according to a study due to be presented in a few days at the American Society of Cardiovascular Annual Meeting in Chicago. Type 2 diabetes.
For this study, Dr. Tomohide Yamada, diabetologist at the University of Tokyo (Japan) and his colleagues did a meta-analysis of 21 studies on the sleep of over 300,000 people from the West and Asia. . They collected data on their sleep cycles, possible naps and daytime sleepiness. They then compared the responses with the information gathered about metabolic syndrome and type 2 diabetes.
Between 30 and 40 minutes of nap maximum
They concluded that people who nap less than 40 minutes during the day have no increased risk of metabolic syndrome but that beyond 40 minutes, this risk is greatly increased. “Taking a nap is a widely used habit, but the ideal is not to exceed 30 minutes. A 90-minute nap is indeed correlated with a 50% higher risk of type 2 diabetes” say the researchers.
These findings could pave the way for new guidelines in supporting people with diabetes.
