Health Topic - Sleeping and Eating

Sleeping not only feels great but it is vital in maintaining homeostasis of the body.

Ours bodies produce the chemicals/hormones lepin and ghrelin, which are important for the regulation of appetite as they control satiety levels in your body. When satiety decrease, hunger increases.


Leptin hormone enhances the feeling of satiety, giving you the feeling of fullness this reducing appetite. You snooze, you lose (weight) theory.

Ghrelin hormone opposes leptin. As ghrelin increases in the body so does hunger. You are much more likely to need food and also to overeat, craving foods high in calories and foods high in carbohydrate.

Carbs provide the body with energy which is why you crave such things when you feel tired. However, if you do not burn all these carbs then the energy intake you have consumed can be converted to fat in the body.


It is thought that sleeping less than 8 hours per night can have detrimental effects of the hormone balance of your body.

Adequate sleep also promotes; immune function, metabolism, memory, learning, cognitive function, mood and other vital functions in the body.
