Why does the penis erect when sleeping?
Our internal organs are dominated by sympathetic and parasympathetic nerves. Sex organs are no exception. Penile erection is controlled by sacral parasympathetic nerve. When the parasympathetic nerve is excited, the penis will erect.
Sympathetic nerve and parasympathetic nerve have a certain tension, and they face each other like a seesaw. When sympathetic nerve is excited, parasympathetic nerve is relatively inhibited.
Stimulated by daytime environment, sympathetic nerve is relatively dominant. Parasympathetic nerves are dominant at night and during sleep, especially during heterogeneous sleep. The male penis will erect and the female genitals will be congested.
How to protect your reproductive health?
1. Be lenient, not tyrannical.
The standard reference value of male semen was 65.438+0.2 billion sperm per milliliter in the late 1980s, but now it is only 20 million sperm per milliliter. There are 1 couples in reproductive period who are confused about infertility. The obvious decrease of male sperm count is closely related to infertility and unhealthy lifestyle. For example, sitting on a soft sofa for a long time, or driving for a long time, will make his private parts oppressed, thus squeezing the blood supply artery. Venous confluence is blocked, and the genitals are in a state of extrusion and deformation, which will definitely affect the function.
Experts suggest that men should not sit on the soft sofa for too long, drive for two hours 15~20 minutes, and often have vaginal contractions twice a day for ten minutes each time. This can not only promote local blood circulation, but also play a strong supporting role.
2. Breathe and don't turn it off.
Men's underwear should be soft and breathable, not tight underwear. It's best not to wear jeans, but to wear loose pants to cool down and get some air. Besides, you might as well sleep naked. Can let private parts enjoy a rare comfortable feeling in a quiet night.
3. Be clean, not dirty.
Men should develop the good habit of washing private parts with warm water before going to bed. Be careful not to wash them with too hot water. Pay attention to the order when washing, and the scrubbing direction should be up first and then down. From front to back, that is, wash the penis and scrotum first, then wash the anus, and prepare a soft towel to wipe.
If the foreskin is too long and you are afraid of surgery, you should be diligent and daily cleaning is essential. When cleaning, turn the foreskin up and thoroughly clean the scales.
