Some people prefer to sleep, leaving night lighting, while not thinking about the fact that such a habit can negatively affect the overall health.
And this also applies to sleep when the TV is turned on or the computer is running.
According to studies conducted by scientists from a single university in Britain, it became known that such people more often than others suffer from obesity, depression, and also face the emergence of psychosomatic diseases. The main reason for this is that the production of melatonin is reduced, which enriches the blood mainly in the period from 22 to 3 o’clock in the morning.
Light Reduces the Production of Hormones
Due to the fact that the room includes light, the production of not only melatonin, but also serotonin, which should provide cheerfulness throughout the day, decreases. It also became known that these hormones are responsible not only for the work of the nervous system, but also strengthen the protective properties of the organism in opposing the development of various diseases, including cancer.
Scientists have learned that the production of melatonin does not allow the appearance of excess weight, but an insufficient amount of this hormone increases the risk of obesity.
Such people are characterized by apathy, fast fatigue, resulting in reduced efficiency, as well as unwillingness to go in for sports, travel, lead an active lifestyle, which ultimately leads to depression, which can not always be managed independently.
A substandard sleep accelerates the aging of cells, which manifests itself in the appearance of early wrinkles, a change in the color of the facial skin that takes on a darker shade, as well as circles under the eyes. In addition, the condition of hair deteriorates, which lose its natural sheen, and the fragility of the nails increases. In order to prolong youth as much as possible and slow down the aging process, it is necessary to sleep in total darkness, and those people who work at night, create optimal conditions, using curtains made of dense material or blinds.
