How does the sun brighten your sex life?
With the arrival of spring, everything around us seems to awaken, and new life begins. And many of you may have noticed that your sex drive is stronger at this time of year than in winter. This is no coincidence. Scientists note that sunlight influences our sexuality. But how does this work?

How ultraviolet radiation affects human sexuality
Ultraviolet radiation has a strong effect on the human body, especially the endocrine system. During this period, active production of sex hormones occurs, which affects a person”s sexuality. This finding is promising and will help doctors combat reproductive disorders in the future.
How the sun influences hormonal levels
The adrenal glands, pituitary gland, endocrine system, thyroid gland, pineal gland, as well as the ovaries and testes, are responsible for the reproductive system.
At the center of this complex system is the hypothalamus, which sends impulses that cause the body to produce or stop producing hormones. The amount of hormones affects human sexual behavior.
Scientists have conducted studies showing that ultraviolet light increases the production of testosterone and estradiol in fish and makes roosters more interested in hens. Ultraviolet light has also been found in humans. It has been found to increase testosterone in men. Therefore, sunlight can not only increase hormone production but also influence sexual behavior. But how exactly?
Israeli scientists have been able to answer this question.
Experiments on mice
First, tests were conducted on laboratory mice. They were exposed to ultraviolet light with a wavelength of 320-400 nanometers. It was observed that the females dramatically enlarged their ovaries, increased sex hormone levels, and extended the mating season. At the same time, a rapid increase in plasma testosterone was observed in the male rodent population.
It was noted that rodents are increasingly engaging in sexual contact and are increasingly attracted to each other. Then the scientists moved on to the second phase of the study, which was carried out on genetically modified rodents. Representatives of this group block the production of the p53 protein. It is this protein that causes skin damage during a sunburn and activates the production of pigment at this moment. Due to its absence, the rodents stopped responding to ultraviolet radiation, and the effect that was observed in mice during the initial experiments disappeared.

Everyone has their own definition of an ideal sex life. Some people like gentle sex, while others cannot live a day without a whip and handcuffs.
Experiments on humans
After conducting experiments on rodents, Israeli scientists decided to test their findings in humans. Participants were selected from 32 people who answered a questionnaire about signs of romance, aggressiveness and sexual activity before the experiment began. Men and women were then required to avoid sunlight for two days. The next day, the experiment participants spent 25 minutes in the sun.
The scientists took samples from the subjects. After men and women first spent a day without sunlight and then were exposed to ultraviolet light, they experienced increases in testosterone and other sex hormones.

The scientists were then asked to mark on a scale how much the subjects” sexual activity had increased. It is worth noting that after the first exposure to the sun, people noticed an increase in their attraction to the opposite sex. At the same time, the male half of the group also showed an increase in verbal aggression.
It also looked at data from thousands of men whose sex hormones were tested that year. It has been found that testosterone levels in men increase significantly during the summer months, especially from July to August when the sun is at its most active.
Conclusions
Research has shown that testosterone production is affected by ultraviolet radiation. This is due to the proteins that make up our skin. This protein, which gives us an attractive tan, may also increase sexual desire.
Scientists have not yet figured out why this process occurs this way. Perhaps this is part of evolution, because for ancient peoples it was much more convenient and comfortable to have sex in the summer than to have an intimate life in the cold season. Or could it be because ultraviolet radiation has led to increased sexual activity during the warmer months and people wearing less clothing?
It is not entirely clear why this happens, but such research opens up great opportunities for future science. In addition to regulating sexual activity, it would be an excellent tool for solving numerous sexual problems that arise in people with the relapse or onset of various diseases.
