How Does Sleep Deprivation Increase My Hunger?

Hi I'm Dr. Michael Bruce, the sleep doctor, sleep that provision increases your hunger in two different ways. Number one, is it changes levels of particular hormones in your system, specifically your level of cortisol tends to raise which increases your appetite also it increases the hormone called goreran which is also something that tells your brain it's time to continue to eat, so be careful and avoid sleep deprivation.
