During the first phase of the study, the men were allowed to sleep normally, spending 8.5 hours in bed for four nights. Furthermore, the sleep was followed by glucose (blood sugar) testing-with the average participant sleeping about 9.7 hours a night. They found that restricted sleep was linked with a 23 percent higher diabetes risk compared with non-restricted sleep.
Even short-term sleep deficit, with four or five hours of sleep per night, can increase the risk of developing diabetes by about 16 percent - comparable to the increase in risk caused by obesity, the study pointed out. But with two nights of extra sleep, insulin levels returned to normal.
According to Josiane Broussard, lead author of the study and Assistant Research Professor with the Sleep and Chronobiology Laboratory at the University of Colorado in Boulder, stated that the study was conducted on a small scale and is relevant only for healthy men.
In the real world, when people don't get enough sleep they tend to overeat, which may limit how much results from this lab experiment might happen in reality, the authors note in a report scheduled for publication in the journal Diabetes Care.
Though prior research warns that sleep deprivation may increase the risk of type 2 diabetes, a new study suggests that "catch-up" sleep might reverse that risk - at least in the short-term.
After both phases, researchers determined the subjects' insulin sensitivity (basically their insulin's ability to regulate blood sugar). Chronically sleep deprived people are more likely to experience inflammation and high blood pressure, are more prone to traffic accidents and less alert, and have difficulty concentrating, reasoning and solving problems.
"By catching up on sleep on the weekends, people are reducing average extent and severity of the effects of sleep deprivation", Gangwisch added by email.
GETTYA link between sleep and diabetes is not commonly looked
Lack of sleep can increase our risk for health problems especially diabetes. A new University of Chicago study suggests sleeping late on the weekends may promote good health.
"Ideally, we would all get sufficient sleep on a nightly basis".
A sleep study in process is shown.
Researchers at the University of Chicago have said that catching up on sleep may help lower the risk of diabetes.
But on another occasion, those same volunteers were sleep deprived - only allowed to spend 4.5 hours in bed for four consecutive nights. That said, it is appropriate for young adults, people with illnesses, and anyone recovering from a sleep debt.
Many of us work long hours during the week.
