Not getting enough sleep (about eight hours a day are recommended) and not following a regular schedule for meals, increases the risk of suffering from numerous conditions such as diabetes, obesity, or premature aging, and may even affect psychologically.

According to Marta Garaulet, Professor of Physiology at the University of Murcia, we have an organic clock that is responsible for regulating the hormones associated with metabolism and the expenditure of energy, and that it is possible to "synchronize" with the environment.

The specialist explains that problems arise when the rhythm of life we ​​lead prevents the organism from synchronizing external agents with this internal clock, and thus produces a mismatch that has a direct consequence of obesity.

In this regard, the doctor states that the fact that there are more and more people with excess weight among the Spanish population is related to the shortage of sleep hours, which makes us more tired and, as a result, our physical activity is less. To which we must add that the hormones that control the intake of food also increase when you do not get enough sleep and the appetite is stimulated excessively, so we need to eat more.

The rhythm of life that we carry prevents the organism from synchronizing the external agents with this inner clock, and thus a mismatch occurs.

In the case of the youngest children, an investigation whose results have recently been published in the International Journal of Obestity, has confirmed that children who sleep less than seven hours a day have a greater weight gain than those who sleep, at least eight hours a day.

The Chronobiology studies the external biological rhythms and their influence on the different functions of the organism, and is associated with the Neuroendocrinology due to the relationship that exists between hormones and the activities they perform in the nervous and endocrine systems.

Dr. Manuel Tena-Sempere, professor of Physiology at the University of Córdoba, points out that neuroendocrine systems intervene in physical development, puberty, reproduction, metabolic control and energy balance, among other functions.
