There are many tips on adequate sleeping hours to achieve good rest and avoid certain health conditions, but there is also a relationship between sleeping hours and overweight.
Sleeping at least 7 hours a day seems to be key to controlling the hormones that regulate our appetite. For many years now, there has been a misconception that sleeping for a few hours has made us lose weight. However, reality is very different, as adequate sleep habits prevent hormonal disorders that can lead to more appetite and eat more food. This process refers to two hormones involved in regulating appetite: leptin and ghrelin.
To get an idea of the importance of sleeping in our weight, the Research Center for Biomedical Surveys on Obesity and Nutrition believes we would reduce the risk of overweight by up to 36% for each additional hour of sleep. "At least 7 hours, it would be appropriate for hormonal mechanisms not to change"Explains the studio."
People who sleep less than 5 hours, compared to those sleeping between 7 and 8, produce higher levels ghrelin i a descent leptin, This first hormone is synthesized mainly in the stomach, whose function is to inform the brain that the body needs to be fed. Therefore, its level increases before meals and decreases after feeding. Leptin is then excreted into fatty tissue (body fat) and goes to the blood where it travels to the brain and other tissues, causing fat loss, reduced appetite or other function.
Then, the most important consequence of these neuroendocrine changes is an increase in appetiteespecially for hypercarbonic foods rich in carbohydrates, try to replace energy that has not recovered the lack of pleasant sleep. And this leads to excessive feeding and, consequently, to weight gain, and, on the other hand, to a lower use of fat reserves.
We can then say that Sleeping several hours a day causes us to eat more foods, we prefer those with lower nutrients such as sugar and fat, we do not have this feeling of fullness or "being satisfied" and besides, our body uses less spare fat.
Remember that excessive body weight and obesity are multiple cause disorders, including the pillars for its prevention and treatment, balanced and healthy nutrition and regular physical activitywithout leaving any side of stress control.
