From a medical point of view, it is not advisable to take a bath before or after sex. Because this approach is very harmful to your health.

We know that a person's sexual excitement is a very complex reflex activity. In addition to the command of the central nervous system, it also requires close coordination of the circulatory system, motor system, endocrine system and reproductive system. cooperation, and at the same time, a certain amount of energy must be consumed.

After taking a bath, the blood vessels of the skin all over the body will be fully expanded, so more blood will temporarily accumulate in the expanded blood vessels of the skin. If sexual intercourse causes acute congestion of the sexual organs, the body must urgently mobilize the blood in the expanded blood vessels distributed in the skin and other places to quickly replenish it, and the distribution of blood throughout the body will undergo a major change. In this way, the blood circulation in the body will be out of balance, reducing the blood supply to other organs, which may easily cause symptoms such as dizziness, fatigue, and heart palpitations. Some people may even experience low blood sugar, causing hypoglycemia. This is caused by the temporary imbalance of autonomic nerve function, which inhibits the decomposition and xenobiotic effects of glycogen in the liver. If you already have coronary heart disease, things will be even worse. In the "battle" for blood, insufficient blood supply to the myocardium will easily occur, causing angina pectoris or myocardial infarction.

It is also not advisable to take a shower after sex. why?

Because sex is a relatively strenuous physical exertion. During sexual intercourse, blood flow to the muscles and sexual organs increases significantly, and the heart rate increases. When sexual intercourse is over, although the blood flow and accelerated heart rate slow down, they will still last for a long time. If you take a shower immediately after intercourse, it will inevitably increase the blood supply flow to the skin and muscles. This causes a reduction in blood supply to other vital organs. If the blood supply to the heart and brain is reduced, their normal physiological functions will be affected, causing symptoms of transient hypotension and cerebral anemia, especially for people with cardiovascular diseases such as hypertension, coronary heart disease, and anemia. You should avoid taking a hot bath immediately after sex. Otherwise, serious consequences may occur.

In addition, hot water bathing can also cause male infertility. According to reports, hot water bathing for one hour can damage male fertility for up to six weeks. Someone has done such an experiment. Men sat in a bathtub with a water temperature of 38°C for 1 hour. After 36 hours, their semen was taken out for examination. It was found that the number of sperm and penetrating power were reduced, but the maximum impact did not appear until 4 weeks later. This Experiments have also proven that immature sperm can be damaged by high pressure. It takes 7 weeks for newly produced sperm to mature and transfer to the seminal vesicles, and it also takes 7 weeks for recovery.

Therefore, friends are advised not to have sex before or after taking a bath.
