This kind of sex makes women young and beautiful

Feeling richer

A survey by the National Bureau of Economic Research found that if married people have regular sex, it will bring them the same happiness as making an extra $100,000 a year.

Improve immunity

After analyzing 111 volunteers aged 16 to 23, the researchers found that having sex once or twice a week can increase the amount of type A immunoglobulin in the body by 30%, thereby increasing resistance and helping people prevent colds and flu.

Good mood

Semen contains nutrients such as zinc, calcium, protein, etc., which are of great benefit to the female body. Moreover, a study also found that women who do not use condoms during sex are more cheerful and less likely to be depressed. However, the researchers also stressed that this result only applies to couples who are loyal to each other.

Sleep well

After orgasm, the human body secretes a hormone called oxytocin, which can make people feel warm and intoxicated. Sex also promotes the release of endorphins, which are natural sedatives that make people feel relaxed and more likely to fall asleep. The effects of these two chemicals were particularly pronounced in men.

Youthful appearance

Sex can make a woman look 12 years younger. In the study, men were asked to look into a mirror and assess a woman on the other side. Women who were rated as "very young" had sex an average of four times a week. This is not a coincidence, because studies have long found that sex can promote the secretion of estrogen, making the skin smoother and the hair shinier.
