PSYCHOLOGY OF EMOTIONS

Detailed explanation-1: -But when we don’t get enough sleep our ghrelin levels don’t decrease as much as they should. Feelings of hunger persist even when the body doesn’t need more calories. So by altering these two key hormones, sleep deprivation leaves us feeling both hungrier and also less full that we actually are.

Detailed explanation-2: -Sleep duration has long been linked to the body’s production of appetite-regulating hormones. Insufficient sleep is associated with higher levels of the hormone ghrelin, which increases appetite, and lower levels of the hormone leptin, which leads to feeling less full. This sets people up to gain weight.

Detailed explanation-3: -Ghrelin is a multifaceted gut hormone which activates its receptor, growth hormone secretagogue receptor (GHS-R). Ghrelin’s hallmark functions are its stimulatory effects on food intake, fat deposition and growth hormone release. Ghrelin is famously known as the “hunger hormone”.
