Young adults cannot use the weekend to catch up on lost weekday sleep. Scientists discovered that losing weekday sleep would lead to late-night eating, weight gain, and lower sensitivity to insulin (the hormone that control blood sugar). You cannot make up for lost sleep during the week by sleeping a few more hours on the weekend. Missing sleep can harm your health. It leads to obesity and type 2 diabetes. In 2014, more than one in three adults slept fewer than the recommend seven hours a night. Researchers looked at three groups of people in their mid-20’s. For approximately two weeks, each group followed a set sleep schedule. The first group slept eight hours. The second group slept only five hours. The third group slept five hours on the weeknights and were allowed to sleep whenever and however much they wanted over the weekend. The third group stayed up until midnight or 1AM on Friday and Saturday nights. The following morning, they slept in until 11AM-noon. They also stayed up late on Sunday, which left them with only six hours of sleep before the workweek started. Over the whole weekend, this group got approximately 1.1 hours more sleep than what their bodies needed. They did get extra sleep, but it was not enough to make up for the sleep they lost during the week. People in the study who got too little sleep, gained weight, as well as the weekend sleep in group. By the end of the experiment, people in both of these groups gained an average of 3.3 pounds. Scientists says this could be because losing sleep interferes with hormones, like leptin, that control hunger. During the work weeks, both groups ate roughly 400-650 calories in late-night snacks. The weekend sleep in group also had a 27% decrease in insulin sensitivity. The insulin sensitivity in the group that slept five hours a night dropped only half as much.
This is brand new breaking news. I chose this article because I wanted to find out if it is possible to catch up on sleep on the weekends. This article is important to the world because it stresses the importance of sleep and how lack of sleep leads to health problems. This article reminds me of when we learned about animals hibernating in the winter.
