Why Not Sleep Late On Weekends?

If you often sleep in on weekends, you may be increasing your risk ofheart disease and diabetes. In fact, a study from the University of Pittsburgh suggests that the greaterthe difference between the time you usually get up on weekdays and how late you sleep on weekends the greater the risk. Researchers tracked 447 men and women ages 30 to 54 and determined that those who slept later on weekends had lower HDL (“good”) cholesterol, higher triglycerides, higher insulin resistance and higher body mass index than those who kept consistent sleep schedules throughout the week. The link between sleeping habits and these factors remained even after the researchers controlled for physical activity, caloric intake, drinking alcohol, and symptoms of depression. During the 7-day study the participants wore devices that recorded when they fell asleep and woke up, and also measured their movements night and day. Almost 85 percent of the participants woke later on days when they didn’t have to go to work. Earlier research revealed an association between shift work and an increased risk of heart disease and diabetes. It’s not yet known whether the effects seen in the study from sleeping in on weekends are long lasting.
