A good night’s sleep helps our body restore and rejuvenate, grow muscle, repair tissue, and produce the hormones we need such as ghrelin and leptin, which control feelings of hunger and fullness. Some scientists have sought to link inadequate sleep with increased risk of obesity. Insulin, which is responsible for the regulation of glucose in the blood also changes due to inadequate sleep and can result in an increase in blood sugar level. For this reason, chronic sleep deficiency is also linked to a higher risk of cardiovascular disease, stroke, diabetes and kidney disease.
