ScienceDaily (Feb. 7, 2009) - A new study in the journal Sleep shows that sleep duration is associated with changes in the levels of specific cytokines that are important in regulating inflammation. The results suggest that inflammation may be the pathway linking extreme sleep durations to an increased risk for disease.

Burning the candle at both ends during the working week could raise a person's risk of developing type 2 diabetes, New York researchers say. People who slept fewer than six hours a night were more likely to develop a condition that precedes diabetes than those sleeping for longer, they found. They said the study supported mounting evidence that cutting back on sleep can have a profound impact on health.
