Is that 6:00 am workout getting in the way of good sleep? Don't think those fat cells won't notice.
A new study published in the Annals of Internal Medicine finds that inadequate shut-eye has a harmful response on our fat cells, reducing their ability to respond to insulin by about 30 percent. 
Over the long-term, this decreased response could set the stage for Type 2 diabetes, fatty liver disease, and weight gain.

(All Things Considered) While the brain sleeps, it clears out harmful toxins, a process that may reduce the risk of Alzheimer's, researchers now say. During sleep, the flow of cerebrospinal fluid to and from the brain increases dramatically, washing away harmful waste proteins that build up between brain cells during waking hours, a study of mice found. "It's like a dishwasher," says Dr. Maiken Nedergaard, a professor of neurosurgery at the University of Rochester and an author of the study in Science. The results appear to offer the best explanation yet of why animals and people need sleep. More (LISTEN)
