Shortened sleep reduces leptin, a hormone which reduces appetite, and increases ghrelin, a hormone which increases appetite notes a review paper on the association of lack of sleep to obesity and diabetes.
Lack of sleep increase risk of diabetes
Numerous studies have also found that lack of sleep increases the risk of diabetes.
“Insulin sensitivity decreases rapidly and markedly without adequate compensation in beta cell function, resulting in an elevated risk of diabetes,” the authors of the paper noted.
