Lost of 1 night sleep increases type 2 diabetes risk

The Endocrine Society's  Journal of Clinical Endocrinology & Metabolism (JCEM) will be publishing a new study that measured the effects of short sleep duration.  
They note that missing just one night of sleep can induce insulin resistance.  In short, this increases the chance of type 2 diabetes.  According to the lead author, Dr. Esther Donga, MD of the Leiden University Medical Center in the Netherlands, the shortened sleep in the past decade also correlated with an increase of type 2 diabetes.  
"Our findings show a short night of sleep has more profound effects on metabolic regulation than previously appreciated," said Donga.  There have been previous studies that show decline in glucose tolerance but this is the first study to examine a single night of partial sleep and its effect on insulin sensitivity.
The clinic study examined nine healthy subjects and measured their insulin sensitivity after a healthy night of sleep (8 hours) and then a night of four hours of sleep.
