Sleep Fat cells

The Big Sleep

Another reason to get ample shut-eye: Your fat cells depend on it.

By now, we are well aware that sleep does the body wonders — from increased brain function to appetite stabilization — and the latest findings published in the Annals of Internal Medicine show that our fat cells, responsible for energy metabolism, are affected as well. Researchers at the University of Chicago Medicine have found that not gettting enough sleep reduces fat cell's ability to respond to insulin, a hormone that regulates energy, by 30 percent. Over time, this could lead to weight gain and diabetes, among other health problems. In case there were any doubters, the evidence is everywhere: Regeneration is critical, and its effects run deep.
