8 Hours of Sleep is Best for Health

Seven young, healthy and lean adults participated in a study at the University of Chicago Medicine ( see article http://annals.org/issue.aspx) for the duration of 8 days.  They slept for 8.5 hours the first four nights and 4 hours for the next four nights.  The participants were given an intravenous glucose tolerance test.  It was discovered that the body’s total insulin response decreased by 16% and the insulin sensitivity of  fat cells decreased by 30 %, after sleeping for less hours or 4 hours per night .

“Body fat, also known as adipose tissue, stores and releases energy. In storage mode, fat cells remove fatty acids and lipids from the circulation where they can damage other tissues.
