Being deprived of sleep for just six hours or a single night may affect the liver’s ability to produce glucose and process insulin, increasing the risk of metabolic diseases such as fatty liver and Type-2 diabetes, warns a study.

Sleep deprivation has been associated with eating more, moving less and having a higher risk of developing Type-2 diabetes.

However, “it was not clear whether glucose intolerance was due to the changes in food intake or energy expenditure or to the sleep deprivation itself,” explained a team of researchers from Toho University in Japan.

In the study done over mice, blood glucose levels were found significantly higher in the sleep deprivation group than controls after one six-hour session of wakefulness.

Triglyceride (fat) levels and the production of glucose in the liver also increased in the sleep deprivation group after a single wake period.

Elevated liver triglycerides are associated with insulin resistance, or the inability of the body to process insulin properly.

In addition, lack of sleep changed the expression of enzymes that regulate metabolism in the liver in the sleep deprivation group.

These findings suggest that “intervention studies designed to prevent sleep deprivation-induced hepatic steatosis and insulin resistance should be performed in the future,” the researchers noted.

For the study, published in the American Journal of Physiology — Endocrinology and Metabolism, the team examined two groups of mice.

One group was kept awake for six hours each night (“sleep deprivation”), while the control group was allowed to sleep as desired.

The team offered unlimited high-fat food and sugar water — mimicking lifestyle-related food choices that people make — to both groups prior to the study.

If you wish to avoid diabetes, better start exercising for just half-an-hour a day, a Harvard University research has found while advising yoga and weight lifting.

According to the research, the chance of developing Type 2 diabetes was cut by between 30 and 40 per cent with just three-and-a-half hours of exercise a week, Daily Mail reported Wednesday.

It was also found that just an hour’s workout every week could cut the risk by 13 percent.

The study, which followed 100,000 women, also showed muscle-strengthening exercises such as yoga and weight lifting fend off the condition.

Scientists showed that those doing at least 150 minutes of aerobic activity a week – and at least an hour of muscle-strengthening – had the best results.

Published by the journal PLOS Medicine, the study was carried out by scientists from Harvard School of Public Health and the University of Southern Denmark.

Researchers studied 99,316 middle-aged and older women, who did not have diabetes at the beginning of the study, for eight years. During the period, 3,491 women developed Type 2 diabetes.

They studied the effects of weekly time spent on resistance exercise, lower intensity muscular conditioning exercises and aerobic moderate and vigorous physical activity.

“Our study suggests that engagement in muscle-strengthening and conditioning activities (resistance exercise, yoga, stretching, toning) is associated with a lower risk of (Type 2 diabetes),” the researchers said.

“Despite limitations to which this research can be applied to women in general, it underlines the message that leading an active healthy lifestyle can help to reduce the risk of Type 2 diabetes,” said Richard Elliott, research communications officer at Diabetes, UK. (IANS)
