Though obesity by itself can drive up heart disease risk, new research suggests diabetes and heart disease risk is especially high when combined with a tendency to stay up late at night.
The finding stems from a comparison of sleep patterns and disease in 172 middle-aged people as part of an ongoing obesity prevention study in Italy.
“The sleep-wake cycle is one of the most important behavioral rhythms in humans,” said lead researcher Dr. Giovanna Muscogiuri. She is an assistant professor in the endocrinology unit of the University of Naples Federico II, in Italy.
For the study, her team grouped participants according to their sleep patterns.
