Is there a relationship between sleep and weight? This is one of the most discussed and analyzed questions in recent years. Several types of research seem to indicate that there is indeed a relationship between these two factors.
The relationship between sleep and weight
There are already various studies that demonstrate the relationship between sleep and weight. These results demonstrate the importance of a good night’s sleep. It is a question of sleeping a correct amount of time, seen as sleeping more or less than the recommended time can be negative for the general well-being.
A study carried out by the UNAM Sleep Disorders Clinic in Mexico City has shown that people who sleep less than seven or eight hours a day are more likely to gain weight. To reach this conclusion, experts studied 68,000 middle-aged American people.
The result of the study showed that women who sleep seven or eight hours are 15% less likely to be obese or have severe overweight problems.
This study has also come to the conclusion that women who work on shifts, that is, who sometimes work during the day and others at night, are more at risk of suffering from type 2 diabetes and being overweight.
Experts believe that the increase in obesity in the world is due, among other factors, to a change in sleep habits. As we all know, sleeping badly means being moody the next day, irritated or with little concentration. But there are also not very obvious and less immediate consequences, such as weight gain.
Why is there a relationship between sleep and weight?
When a person sleeps more than eight hours or on the contrary less than five hours, a hormonal disturbance occurs in his body. This irregularity is one of the main factors in weight gain. In this sense, the hormones that regulate hunger and satiety, known as ghrelin and leptin, remain affected.
On the one hand, ghrelin is the hormone responsible for indicating to the hungry organism. Leptin, on the other hand, is the hormone responsible for indicating to the body that it no longer eats because it is now full.
When a person sleeps more or less than the recommended hours, the levels of these hormones are affected. Ghrelin is produced in excess causing a greater appetite and the production of leptin does not reach the necessary minimum levels.
Because of this hormonal disorder, the person will be much more hungry and his satiety level will be lower; the consequence will be an increase in weight.
Decreased physical activity
The chances of a tired person doing physical activity decrease considerably. This factor also influences weight gain, which is indirectly related to a night’s sleep.
Many experts have shown that people who do not sleep sufficiently are more likely to be sedentary and spend more hours in front of the television.
There also appears to be a relationship between sleepless and a decrease in body temperature. The main consequence is that energy consumption also decreases; for this reason we end up using a considerably smaller percentage of energy from fat reserves.
The studies carried out so far also indicate that this weight gain in direct relation to sleep, affects indifferently at any age and equally between both sexes. A different thing is the case of children, who have a greater physiological need to sleep. The general advice is to try to have a healthier lifestyle possible also with regards to habits. For this, it is necessary to organize a diary to be able to calmly do all the activities of the day. It is important to try to sleep between seven and eight hours a day to have an active and energetic day.
