Harmonious Sexual Life and Healthy Longevity: Physiological and Psychological Benefits of Men's Health

Sexual activity between spouses is not only a means of procreation but also a normal physiological and psychological activity. Normal, moderate, harmonious, and regular "bedroom pleasures" not only bring happiness to the couple but also have a good relieving and inhibitory effect on some ailments—headaches, backaches, depression, etc.—and are conducive to health and longevity. People's emotions of joy, anger, sorrow, and happiness are closely related to physical health. When negative emotions such as anger, anxiety, tension, guilt, and sadness persist, they can cause negative physiological effects and ultimately weaken the immune system. Sexual activity has a "detoxifying" effect on negative emotions, promoting positive emotions such as pleasure, lightness, and excitement. During sexual activity, the central nervous system releases a natural analgesic—endorphins. All of these "put the entire physiological system in a relaxed and beneficial state, which is conducive to the regeneration of bodily functions." This is the conclusion reached by Dr. Reed Moscovitz, director of the Sexual Dysfunction Clinic at New York University Medical Center, after research.

Studies have found that excessive psychological and mental stress can damage the immune system, making people more susceptible to colds, high blood pressure, and ulcers. Sexual activity, on the other hand, can relieve stress and allow the body to completely relax. Although this effect only lasts for a few hours, regular sexual activity can provide a sustained and stable sense of relaxation. Because sexual activity can quickly relax the body, it also helps eliminate insomnia. The more fulfilling the sexual experience, the easier it is to fall asleep afterwards. Sexual activity has a more significant effect on women's health. In the early 1980s, scientists made a surprising discovery: semen contains an antibacterial substance comparable to penicillin, named "seminal plasma." Once it enters bacterial cells, it can inhibit the synthesis of bacterial ribonucleic acid (RNA), thereby inhibiting and killing bacteria. Experiments have shown that seminal plasma can kill pathogenic bacteria such as Staphylococcus, Streptococcus, and Pneumococcus. Therefore, semen can help disinfect the female vagina and prevent microbial invasion. If couples have long intervals between sexual intercourse or abstain from sex for many years, these women have an increased chance of developing vaginitis, endometritis, and salpingitis. For some women, sexual activity can also alleviate premenstrual syndrome. In the 5-7 days before menstruation, increased blood flow to the pelvis can cause swelling and cramps. The muscle contractions caused by orgasm can accelerate blood flow out of the pelvic area and into the general circulation, thereby reducing pelvic pressure.

Japanese medical expert Kiyoharu Kawa listed regular sexual activity as one of the secrets to longevity. Dr. Asamasa Nakamoto of the University of Tokyo pointed out in his book "Preventing Brain Aging" that people who do not have sexual activity will experience "use it or lose it"—a phenomenon known as "sexual atrophy." Appropriate sexual activity helps maintain brain youth, prevent brain aging, and promote metabolism. Swedish researchers compared sexually active elderly people with elderly people living alone and found that the former had more energy and stronger memory. Researchers also surveyed 800 representative women aged 38-60, as well as married and single men and women over 70. The results showed that abstaining from sexual activity can lead to a decline in memory and intelligence.

Scientists have also confirmed that moderate sexual activity can increase testosterone secretion in men, not only enhancing sexual performance but also, due to the systemic effects of testosterone, leading to more developed muscles, increased weight, improved bone marrow hematopoiesis, and reduced fat accumulation. For women, it can enhance ovarian function, normalize menstruation, and delay menopause. Scientific research has also confirmed that sexual activity increases the movement of the pelvis, limbs, joints, muscles, and spine, promoting blood circulation, enhancing heart function and lung capacity, and effectively reducing the incidence of heart disease and myocardial infarction. Dr. Alexander Lowen, director of the New York City Biological Research Institute, found in a survey of 100 women with heart disease that about two-thirds had experienced unsatisfactory sexual experiences before their illness. Furthermore, a survey of 131 men found that two-thirds of them had experienced significant sexual problems before their heart attacks.

Of course, excessive sexual activity is harmful to health and can even lead to premature aging. Excessive sexual activity in men can cause impotence, premature ejaculation, or difficulty ejaculating, resulting in premature loss of sexual ability; excessive sexual activity in women can lead to menstrual irregularities, urinary tract infections, and reproductive system infections.

Modern sociologists and andrology experts believe that sex is the light of life, accompanying a person throughout their life; sex is something that a person practices throughout their life.
