Deep sleep is vitally important for establishing metabolism and regulating insulin and blood glucose during the daytime.

“Your body also goes through specific patterns of metabolism. Now, this relates to recent findings just this last year in which researchers monitored the output of people's breath and the various metabolic factors present in the breath as well as through blood draws, So basically doing all this while people are asleep in a laboratory. And they observe that during the first half of the night while people are in deep sleep, their body is actually metabolizing energy very differently than it does in the second half of the night.”
