From the perspective of Chinese medicine, women are cold, so they are afraid of cold; Men are dry by nature, so they are afraid of heat. From a physiological point of view, the difference of reproductive system between men and women also causes the "difference" of their body temperature. Testicles in male reproductive organs are not resistant to high temperature, so they need to be kept below body temperature, otherwise they will harm sperm. A woman's uterus is like an upside-down pear, cool. If you don't keep warm, you will have irregular menstruation and dysmenorrhea. Therefore, women need warm care more.
So why are men afraid of heat and women afraid of cold? David, a professor of biophysics in the United States, explained that men have more muscles, eat more and have faster metabolism, so their body surface temperature is higher than that of women. Physiologically speaking, women are more sensitive to cold than men, and the "temperature sensor" in men's skin is more dull, which is not enough to "know the cold and know the heat". Therefore, even if the temperature is low, men are still hot and women are still cold.
The crotch cools down.
Male scrotum has the function of temperature regulation, just like an "air conditioner", which regulates the temperature of the whole reproductive organs. Experts say that the habit of riding a bike or driving for a long time, wearing thick jeans, putting a laptop on your lap and sitting on a loose sofa for a long time will lead to the scrotum being surrounded and oppressed, which will not adjust the temperature normally, which will increase the temperature of the testis and affect reproductive function. Therefore, it is best for men not to wear tight jeans, and underwear should be loose, comfortable and breathable. Men like taxi drivers and office workers, and it is best to get up every 40 minutes for 8- 10 minutes.
