You used to go to the kitchen for a second dinner late at night?.

Then know that eating at night is harmful to the skin of the face: you become more vulnerable to sunlight, according to an online edition for girls and women from 14 to 35 years old Pannochka. net According to American scientists, an unnatural schedule of nutrition weakens the protective barriers of the skin and increases the extent of damage caused by ultraviolet light. This is confirmed by experiments with rodents, which were fed at night, and then subjected to weak UV radiation.

The co-author of the study, Dr. Joseph Takahashi (Joseph Takahashi) from the Department of Neurology at the Southwestern Medical Center of the University of Texas in Dallas, reports this in Cell Reports.

Circadian rhythms, sunburn and cancer.

According to Texas neurologists, abnormal diet changes the circadian rhythm of animals, reducing the daily activity of sunscreen skin enzyme. This fact affects not only the quality of your tan: ultraviolet rays damage the DNA of cells, promoting premature aging, sunburn and malignant degeneration.

UVA rays, which account for up to 95% of the solar radiation at the surface of the Earth, can penetrate deep layers of the skin. They are the leading cause of senile wrinkles and skin cancer.

The second type of radiation, UVB, has a superficial effect and does the most damage to the outer layers of the skin. This type of sunlight causes sunburn and cancer.

Sun protection clothing and special cosmetics are the best ways to protect the skin from the potentially harmful effects of ultraviolet rays. However, a study by Dr. Takahashi and his colleagues tells us that adherence to a normal diet is also important.

XPA enzymes and cell aging.

During the experiments, scientists fed one group of mice only during the day, and the second - exclusively at night (abnormal feeding time for rodents), subsequently determining the sensitivity of the skin to ultraviolet rays. It was possible to find out that night nutrition significantly increases the damage to cells even with weak UV radiation.

Deep in the causes of this phenomenon, the authors drew attention: a violation of the circadian rhythm of animals leads to a decrease in the daily activity of enzymes XPA (xeroderma pigmentosum group A). This group of enzymes is designed to protect cells from harmful high energy rays.

The deadly effect of the translation of a biological clock.

It turned out that the translation of the biological clock affects the expression of 10% of the skin genes, the consequences of changes in the expression of these genes are unclear. Be that as it may, the connection between eating disorders, shifting circadian rhythms and the activity of genes causes serious concern.

"Now we are going to cross-check this data in public. We believe that if you eat with a natural regime, it gives better protection not only from ultraviolet rays, but also from other damaging environmental factors, as was the case with mice, "said Dr. Takahashi.
