Healthy sleeping habit cuts diabetes risk

London: Here`s an advice for obese teenagers -- if you want to reduce the risk of developing diabetes, make sure that you get eight-and-a-half hours of sleep daily, says a new study.

Researchers have carried out the study of 62 teenagers and found that sleeping for between seven-and-a-half and eight -and-a-half hours a night kept insulin and blood sugar at the optimum level.

Spending less or more time in bed increased the chance of raised glucose levels, while a lower amount of deep sleep caused insulin levels to drop, according to research published in the `Diabetes Care` journal.

The teenagers in the study were monitored over one and a half days, during which their blood sugar levels were tested and their sleep patterns were analysed by the researchers.

The findings mean that a healthy sleeping pattern could help to ward off the onset of diabetes in the patients, all of whom were obese, researchers from the Children`s Hospital of Philadelphia said.

Dr Dorit Koren, who led the study, said it backed up previous research which showed that adults who were deprived of sleep had a higher risk of type two diabetes. "Our study found to keep glucose levels stable, the optimal amount of sleep for teenagers is 7.5 to 8.5 hours per night," he said.

The researchers will now try to back up their findings by carrying out a similar analysis in obese teenagers` homes rather than in the laboratory, a newspaper reported.

"In the meantime, our study reinforces the idea that getting adequate sleep in adolescence may help protect against type 2 diabetes," Dr Koren said.
