Exposure to sunlight increases passion.
Research has shown that exposure to sunlight increases sex drive in both sexes. Ultraviolet radiation is known to increase testosterone levels in men. It plays an important role in both behavioral and hormonal regulation of sexuality. However, it was unclear what underlies this physiological process. A study by Tel Aviv University allowed for a better understanding of the nature of this phenomenon.
First, experts conducted experiments on mice, which were exposed to UVB rays with a wavelength of 320-400 nanometers. The effect was impressive: the level of hormones in females increased significantly, the rutting season extended, etc. Approximately the same picture was observed in males. Both sexes increased their sex drive.
In the next step the scientists obtained evidence that exposure to sunlight through the skin was the cause of the observed hormonal, physiological and behavioral changes, by removing a special protein that protects the skin from the harmful pressure of the rays. That is, the protective system of the skin under the sun somehow activates the endocrine system and promotes sex drive.
After that, scientists conducted an experiment on humans. It was attended by 32 people who filled out questionnaires with questions related to romantic passion and aggression. After applying solar "therapy", both sexes showed an increase in romantic moods, and men also noted an increase in the level of aggression.
In the future, this discovery may lead to practical applications such as UVB treatment for disorders of sex hormone production. However, before this can be achieved, more research is needed. According to scientists, this breakthrough will also lead to further discoveries in fundamental science: “The work opens up many scientific and philosophical questions. We are human, and we have no fur, and therefore our skin is exposed directly to sunlight. We are just beginning to understand what this effect does to us, and what a key role it can play in various physiological and behavioral processes. This is just the tip of the iceberg."
