Inconsistent sleep schedule or portion of a lack of sleep can increase the risk of type 2 diabetes.
Researchers from Brigham and Women's Hospital in Boston monitored 21 healthy adults who were asked to stay in the laboratory during the experiment. For three weeks, participants were scheduled to sleep less than 6 hours per day and sleep late every day.
The results showed that participants' ability to regulate blood sugar levels become disturbed so that participants may have developed diabetes if the experiment continued.
"High glucose levels for a long time, even up to the level of pre-diabetes in some participants," wrote the researchers in a study published in the journal Science Translational Medicine.
New research suggests that hormone levels change with the lack of sleep which may help explain how it links with obesity and weight gain, says Fonseca.
In the study, researchers conducted blood tests to measure levels of several hormones, including insulin, cortisol (which is associated with stress), leptin and ghrelin (which is associated with the regulation of appetite).
Researchers found that disrupted sleep schedule resulted in 32 per cent reduction in the amount of insulin as a key to blood sugar regulation is issued in the body after eating.
Reduction in insulin levels is one explanation of how the disruption or lack of sleep can lead to diabetes, said Lisa Rafalson, professor of pediatrics and family medicine at the University of Buffalo.
"Chronic sleep disturbance is in progress indicate a kind of injury to the body from time to time," said Rafalson.
Stress hormones that make the body can eliminate the hormone balance maintained. "Insulin can not do their work efficiently so that you end up with excess glucose remains in the bloodstream," he said.
In contrast, the present invention other dubious notion that the increased appetite caused by sleep deprivation could explain the reason for the increased risk of diabetes.
Researchers assert that insufficient sleep causes ghrelin levels higher so the appetite hormone leptin levels rise but lower sehingg signals the brain satiety, Rafalson said. But in this new study the researchers did not notice any changes in hormone levels.
Researchers also need to understand whether there is a solution to prevent the increased risk of diabetes in addition to increase the hours of sleep, said Foncesa.
"The reality is that many people whose sleep disturbed because of the conditions of work. We need to identify if there is anything else they can do to fix it," he said as quoted by Fox News,
