The health effects of moderate sex life (adult novel about sex knowledge)

Introduction: Sex is an enjoyable activity for men and women. Apart from human instinct, its purpose is to seek pleasure. Sexologists have found that sex is a natural sedative and analgesic that can improve the function of the immune system. Below are the latest research from the United States and Japan.
1. Exercise: Research from the Pennsylvania Medical College believes that sex life is equivalent to jogging. If you have sex three times a week, it is equivalent to jogging 75 kilometers in a year, and the heat energy burned is 7,500 calories. Regular sex can promote metabolism. Some people say that making love is exercise in bed. During sex, the breathing is deepened unconsciously, thereby increasing the amount of oxygen obtained by the cells and promoting the functions of various organs and tissues in the body. This seems to have some basis.
2. Increase hormone secretion. Men secrete a hormone called deoxyandrostenone every day, and men also need to supplement this type of androgen regularly, because only in this way can they maintain male characteristics. During sex, especially before orgasm and ejaculation, the body can naturally release 3-5 times more of this hormone than usual. Therefore, in the West, many men do not take medication to supplement hormones, but hope that the body can naturally release such masculine hormones. For women, estrogen can help them maintain good blood circulation. Women who have regular sex lives have much higher estrogen levels than those who have sex occasionally.
3. Protect the prostate. Regular ejaculation in sexually mature men can help clear the prostatic fluid accumulated in the prostate. Every time you ejaculate, 1/5 is sperm and 4/5 is semen, which includes a large amount of prostatic fluid. If you don't ejaculate for a long time, old prostatic fluid will accumulate in the prostate. However, it should be noted that sexual life should not be excessive, because frequent sexual life will cause the penis to be in a state of chronic congestion, leading to prostate hypertrophy or swelling, which makes it easy to suffer from chronic prostatitis.
4. Effectively reduce the occurrence of heart disease and myocardial infarction. Sexual life can make the pelvis, limbs, joints, muscles, and spine more active, promote blood circulation, and enhance heart function and lung capacity. People who have a harmonious sex life have at least 10% lower risk of heart disease than those who have an unhappy sex life. However, there have been reports of some people dying suddenly during sexual intercourse due to sudden myocardial infarction, so if you have signs of heart disease, you should avoid overly strenuous sex.
5. Relieve pain. Sexual intercourse (especially during climax) can relieve pain caused by trauma, joint pain, back pain and headache. The endorphins released during sexual excitement and orgasm can improve the ability to endure pain.
