Less sleep linked to higher type 2 diabetes risk
Another 2007 study suggested that short sleep duration is associated with type 2 diabetes. James Gangwisch, PhD, of Columbia University in New York City and colleagues analyzed data from almost 9,000 subjects who participated in a survey between 1982 and 1992.
People who slept five or fewer hours a night or nine or more hours a night were more likely to be diagnosed with diabetes than those who said they slept seven or eight hours a night (this type of study can't definitively prove one caused the other, it only shows that they appear to be causally related).
The studies show a surprisingly consistent correlation between lack of sleep and diabetes risk, according to Dr. Kramer, a regional spokesperson for the American Academy of Sleep Medicine, who was not involved in either study.
"In current medical science, it appears that chronic sleep deprivation is a pro-inflammatory state that may contribute to the hardening of the arteries, as evidenced by increased stress hormones and increased sugar levels in the body," he said.
