Did you know? It turns out that sunlight is an important substance to enhance male vitality, no wonder people often use “sunshine boy” to describe energetic men. Some studies show that men who are unable to conceive are generally deficient in vitamin D, and sunlight can promote the body’s synthesis of vitamin D. Therefore, it is recommended that men who intend to have children get more sunshine! A foreign study tested the sperm quality of more than 300 men and analyzed 40 of them in detail. The results of the study showed that men who regularly sunbathe have faster sperm and better penetration, and women are more likely to get pregnant. Vitamin D plays a decisive role in the production of semen, not only helping it to form, but also making it more active. It has been measured that the activity of vitamin D receptors in the semen of normal men is three times higher than in the semen of those who are infertile. The amount of vitamin D in a man’s body is directly proportional to androgen. Men with low vitamin D levels have a severely lower than normal number of healthy sperm. In October of each year, as winter sets in in Europe and sunlight decreases, the body’s access to vitamin D is reduced. By March of the following year, the body’s level of vitamin D intake from sunlight falls to its lowest. During this period, testosterone in men’s bodies is also at its lowest and their libido is weaker. Although sun exposure can enhance sperm vitality, irrational sun exposure can increase the risk of skin cancer. It is recommended to choose a temperature of 18 to 20 degrees Celsius is ideal, preferably for outdoor exercise, exercise can help the absorption of vitamins. The time spent in the sun should not be too long, up to 2 hours, and also avoid the 12:00 to 15:00 noon when the sun is strongest. Do not wear white clothes, especially when the ultraviolet radiation is strong, white clothes will reflect the ultraviolet radiation to the face or bare arms, so that the skin sunburn, wear red clothes sunshine is most appropriate, afraid of glare can also wear sunglasses. Need to be reminded that the sun do not apply sunscreen, so as not to affect vitamin D synthesis.
