The connection between lack of sleep and diabetes and obesity
Studies have shown that even short term sleep deprivation can lower glucose tolerance and raise cortisol levels. Prolonged lack of sleep puts the body under a state of 24/7 stress which causes it to continuously pump cortisol into the bloodstream, which causes the body to increase its glucose levels in response to the perceived stress.
The increased glucose levels then trigger the body to pump out ever increasing amounts of insulin in an attempt to lower the glucose level. Over time, this leads to insulin resistance and, ultimately, diabetes.
As a consequence, other studies have shown that sleep deprivation not only increases your likelihood of getting type 2 diabetes, but also your likelihood of getting the more severe forms of diabetes.
