Not long ago, Forbes, an authoritative business magazine in the United States, changed its boring economic commentary style and for the first time revealed to readers the beneficial medical effects of positive sex: extending lifespan. Experts from the Royal University of Belfast, the capital of Northern Ireland, have found that men with strong libido and frequent orgasms have a mortality rate that is half lower than those who rarely have sex.
Regular and moderate sexual activity not only brings pleasure, regulates the blood circulation system and endocrine system, but also plays an important role in helping people discover diseases that they may not notice in their daily lives.
Among these diseases, the most common are inflammation and trauma. For men, if ejaculatory pain occurs during sexual activity, it may be caused by urinary system inflammation such as prostatitis and urethritis. These inflammations can cause local tissue congestion and swelling, and a series of contractions during ejaculation are a mechanical stimulus to these organs, often accompanied by pain during ejaculation. If a man experiences bloody semen during ejaculation, that is, blood, it is important to pay attention to whether inflammation occurs in the prostate and seminal vesicles. Inflammation can increase the fragility and permeability of blood vessels, leading to increased pressure during ejaculation. Small blood vessels in the inflamed area are prone to rupture, allowing blood to enter. A small portion of blood semen may be caused by seminal vesicle tumors.
Female friends should also pay attention to "inflammatory signals". If symptoms such as vaginal bleeding and pain occur after sexual intercourse, it is important to pay attention to whether you have contracted diseases such as cervical erosion and vaginitis.
1. Olfactory dullness:
Sexual activity can stimulate the formation of many new neurons in the olfactory center of the brain's rod-shaped cells, enhancing the sense of smell.
2. Heart disease:
Having sex more than three times a week can halve the risk of myocardial infarction and stroke in men.
3. Flu and cold:
Scientists at the University of Pennsylvania in the United States have found that having sex once or twice a week increases the number of immunoglobulin A antibodies in the body by 30%, which plays a role in preventing influenza and colds.
