Dr drexler, an American medical expert, published an article entitled "The Health Benefits of Normal Sexual Life" in the American magazine "Men's Health". We can sum up the following nine benefits:

1. It is helpful for bodybuilding. Sex is a kind of exercise. Having sex three times can consume 7500 calories, and one year's sex life is equivalent to running 120 kilometers.

This is good for the heart and lungs. Sexual life can strengthen lung function, increase the amount of oxygen absorbed by cells, and help improve the functions of various organs and tissues of the human body.

3. It can lower cholesterol. Sexual life can not only adjust the proportion of "good" cholesterol, but also reduce cholesterol.

4. It can relieve and eliminate pain. Dr. Bopp, president of the American Sex Education Alliance, believes that sex can eliminate joint pain and headache.

5. It can increase male hormones. During sex, the human body will secrete more deoxyisoandrosterone, especially at orgasm, the concentration of deoxyisoandrosterone in the blood will increase five times than usual, which will help to strengthen the body and bones.

6. It can protect the prostate. Prostatic diseases are mostly caused by prostatic fluid, which can be eliminated by regular penis movement.

7. It helps to relieve mental stress. Satisfaction or fatigue after sexual life is conducive to mental pleasure and muscle relaxation.

8. It can promote the harmony of husband and wife's life. The contact of love will stimulate sexual desire and increase the concentration of oxytocin in the blood. Oxytocin can increase sexual desire between husband and wife.

9. It can rejuvenate women. Sex life is more important to women. Regular sexual life can increase women's hormone concentration, help prevent heart disease, and make skin shiny and refreshing.

Normal people's demand for sex is almost life-long, that is, most people's desire for sex life will always exist from adolescence to old age. The sexual life of middle-aged and elderly people has its own characteristics. Although the frequency intensity is not as good as that of youth, it will be more touching and delicate psychologically.

Gao Lian, a health care scientist in the Ming Dynasty, said in "Respect for Life in Basket": "Harmony of Yin and Yang, properly connected, can prolong life." The dependence and sexual life of men and women are the requirements of nature and the needs of human nature. If it is excessively inhibited, it will bring many diseases and even premature death.

Normal sexual life can coordinate various physiological functions in the body, promote the normal secretion of hormones and help activate human cells. For men, it can increase the secretion of male testosterone, which can not only enhance sexual function, but also make men muscular, gain weight, improve the hematopoietic function of bone marrow and reduce the storage of fat in the body, which is due to the activation of testosterone on the whole body. For women, moderate sexual life can enhance the physiological function of ovary, improve the immune function of cells and delay the aging process. Healthy sex life can also make women's skin smooth and delicate, their hair dark and thick, their nails shiny and elastic.

According to a survey by the US Department of Health, married people live longer than single people. Among married men aged 25-34, the mortality rate of married men is 0. 15%, and that of single men is 0.35%. Among women, the death rate of single people of all ages is twice that of married people. Modern medicine believes that the incidence of breast cancer among unmarried, divorced and widowed people is significantly higher than that of ordinary people, which shows that normal, moderate and regular sexual life is also of positive significance to the prevention of breast cancer.

Many foreign experiments have proved that appropriately prolonging "sexual youth" (of course, according to everyone's specific physical condition, too weak to be forced) can make people live longer.

Sexual life is blocked, which will make people's physical and psychological imbalance, lead to further sexual dysfunction, and even cause lesions. "Men can't live without women, and women can't live without men", as our ancients said a long time ago. Of course, moderate sexual desire is a very important principle for menopausal men and women whose physical function and sexual ability are declining, otherwise it is harmful to the body.
