Why does the penis sometimes have an erection during sleep? There are three ways to protect reproductive health for this reason

Do male friends sometimes fall asleep. When you suddenly wake up, you will find that your little brother has already "woken up". Why is it so energetic at night? So what exactly is going on?

Why does the penis also have an erection during sleep?

Our viscera are innervated by Sympathetic nervous system and Parasympathetic nervous system nerves. Sexual organs are no exception. Penile erection is dominated by the Parasympathetic nervous system nerve of the sacral cord. When the Parasympathetic nervous system nerve is excited, the penis will erect.

Both Sympathetic nervous system nerve and Parasympathetic nervous system nerve have certain tension, and they fight against each other like a seesaw. When Sympathetic nervous system nerve is excited, Parasympathetic nervous system nerve is relatively inhibited.

In the daytime, Sympathetic nervous system nerve is relatively dominant due to various environmental stimuli. During quiet and sleep at night, especially in heterogeneous sleep, the Parasympathetic nervous system nerve is dominant. There will be male penile erection and female genital congestion.

How to protect one's reproductive health?

1. Be lenient and not oppressive

The standard reference value for male normal semen was 120 million sperm per milliliter in the late 1980s, but now it is only 20 million sperm per milliliter. One out of six couples during their reproductive period has infertility confusion, with a significant decrease in male sperm count and infertility closely related to unhealthy lifestyles. For example, sitting on a soft sofa for a long time or driving for a long time can compress his private parts, thereby squeezing the blood supply to the arteries. The obstruction of venous convergence and the compression and deformation of the genitalia will inevitably affect their function.

Experts suggest that men should not sit on soft sofas for too long. They should exercise for 15-20 minutes after driving for two hours, and regularly engage in perineal contractions for more than ten minutes twice a day. This not only promotes local blood circulation, but also has a strong supportive effect.

2. Breathable and not enclosed

Men's underwear should be soft and breathable, and should not be worn too tight. It's best not to wear jeans, but to wear more loose pants to cool down and let it breathe. Additionally, it's best to sleep naked. It can provide a rare and comfortable feeling in private areas during quiet nights.

3. Be clean and free from dirt

Men should develop the good habit of washing their lower bodies with warm water before going to bed. Be careful not to wash them with too hot water, and pay attention to the order of cleaning. The direction of wiping should be from top to bottom. From front to back, wash the penis and scrotum first, then the anal area, and prepare a separate soft towel for wiping.

If the foreskin is too long and you are afraid of surgery, you should be more diligent. Daily cleaning is essential. Every time you clean the foreskin, you should turn it up and thoroughly clean the Smegma.
