One all-nighter is all it takes to trigger insulin resistance, one of the key components of type 2 diabetes.
Even a short night sleep caused insulin resistance. The study measured the insulin sensitivity of nine people after two separate nights of sleep. The first night the subjects slept eight hours. The second night their sleep was restricted to four hours.
Following the second night, researchers detected insulin resistance.
This condition occurs when the body produces insulin but fails to properly respond to glucose in the bloodstream.
The authors of the study believe insulin sensitivity can change depending on the amount of sleep in the previous night.
Past studies have found shorting sleep for multiple nights leads to impaired glucose tolerance.
The study is the first that sleeps at the effects of only a single night of deprived sleep.
