In addition, this method is the most affordable.
American experts came to the conclusion that prevention of obesity is important to sleep properly and, in particular, to sleep at least 7.5 hours.
Research conducted by American scientists has discovered a direct correlation between the weight of the person and how much he sleeps. Physicians are reminded that the appetite in the human body control the two hormones – ghrelin (the hunger hormone) and leptin (satiety hormone). According to them, the level of both hormones depend on a night’s rest: if a person does not sleep in his body increase the content of ghrelin, stimulating appetite, and decreases leptin content, which will be late to be felt satiety.
American scientists have identified a significant increase in the levels of ghrelin at night in people suffering from insomnia. According to the researchers, that emerging hormonal imbalance and an increased appetite in the afternoon hours, resulting in further to gaining excessive weight.
In addition to the emergence of imbalance between gelina and leptin in the result of lack of sleep, lack of sleep also leads to increased content in the body of another hormone – cortisol, responsible for stress. It cortisol pushes the person to eat something “sweet” – high-calorie foods, which aims only to improve the mood.
The brain attack inhibits cortisol secretion of growth hormone. In the phase of deep sleep growth hormone helps the body turn fat into calories that helps in a result to maintain a healthy weight and to reduce excess. But in the case of insomnia or lack of sleep, the body does not have time to do this work and so there is an accumulation of fat.
The expert on sleep – Michael Breus, working in a rehabilitation center Southwest spine and sports (Scottsdale, AZ), says that an adult must sleep at least 7.5 hours per day to avoid weight gain. According to Breus, the results of the study confirm that normal weight due to three factors – diet, moderate exercise and a full bed.
