1. Weight Control
Sleep plays an important role in weight control and affects two important appetite hormones in our body – Leptin, and Ghrelin. Leptin is an appetite-reducing hormone, so when Leptin levels are high, we usually feel full; Ghrelin is an appetite-stimulating hormone that causes us to crave food.
Lack of sleep increases Ghrelin and decreases Leptin. And a combination of these two conditions can increase a person’s appetite, making calorie control more difficult. In addition, Ghrelin rises fastest from 11 pm to 1 am. If we are awake at this time, we may want to eat high-fat and high-calorie foods. On the contrary, if you fall into a deep sleep during this time, it will not only boost metabolism but also help burn body fat.
