Sleep deprivation is responsible for weight gain

Whether it's looking at work or living a life overwhelmed by social media, it will expose the human body to light, to eat and to move in time, where our members and cells are waiting for darkness. , tranquility and sleep. In this context, a series of studies shows that many environmental factors contribute to disrupt the biological clock: exposure to noise when you sleep in an overcrowded place, for example, or noise in the street, which reduces the quality of sleep.

Other studies show that exposure to light at night also disrupts the biological clock.

Lack of sleep is responsible for poor brain decisions because it reduces the brain's forward activity responsible for decision making and control, while stimulating the desire to eat, the brain can not resist a second candy, for example. In a study published in the American Journal of Clinical Nutrition, it was recommended for people with insomnia or lack of sleep to take extra meals rich in starches and sugars. In another study, it was reported that people who slept little had twice as much fat as those who slept for eight hours. The scientific explanation is the imbalance in the secretion of the hormones of leptin and hormones of ghrelin, responsible for regulating the sensation of hunger and satiety.

What is the relationship between sleep and metabolism?

Sleep is the food of the brain: people who sleep enough, seven to nine hours of sleep a night, leave to their body the functions badigned to it, in the absence of vigilance.

Lack of sleep in turn leads to the rise of cortisol, the stress hormone that gives the body a signal of energy conservation, to use during waking hours. In other words, cortisol slows the metabolic process, that is, the use of energy, which is one of the factors that lead to weight.

Another negative feature of sleep deprivation is the way the body reacts to meals containing starchy foods and sugars, or what we scientifically call "insulin sensitivity". In the context of four days of insomnia, the sensitivity to insulin drops by 30% due to the body's reduced ability to produce insulin, the hormone responsible for the insulin. 39, the use of sugar in the production of energy.

This deficiency is responsible for the incorrect use of sugar and poses a problem of treatment of fats in the blood, which stores them in the body. People who complain about the problem are the most likely to develop type 2 diabetes.

There is no precise hour of immortality, but an ideal hour for that, from 8 pm to midnight, so that each of us calculates the time we need to wake up, and eight hours back to set the preferred sleep time,. For example, an employee who wants to get up at 6 am must sleep at 10 pm to have a "healthy" nap.
