I briefly touched on the subject of sleep and glucose control here. The researchers in this case state that "just one night of short sleep duration can induce insulin resisitance."
The lead author of the study goes on to state:
"Our data indicate that insulin sensitivity is not fixed in healthy subjects, but depends on the duration of sleep in the preceding night," said Donga. "In fact it is tempting to speculate that the negative effects of multiple nights of shortened sleep on glucose tolerance can be reproduced, at least in part, by just one sleepless night."
Just one more piece of the puzzle.
