Before and after sexual activity, it is important not to take a shower immediately after sexual activity, as its hazards include

From a medical perspective, it is not advisable to take a shower before and after sexual activity. We know that a person's sexual excitement is a very complex reflex activity, which requires close and coordinated coordination of the circulatory system, motor system, endocrine system, and reproductive system in addition to the command of the central nervous system. At the same time, it also requires a certain amount of energy consumption.

After taking a shower, the blood vessels in the whole body's skin will fully expand, so there is a temporary accumulation of more blood in the dilated blood vessels of the skin. If sexual intercourse causes rapid congestion of the sexual organs, the body must urgently mobilize the blood distributed in the dilated blood vessels of the skin and other areas to quickly replenish, resulting in a significant change in the overall blood layout. In this way, the blood circulation in the body will be imbalanced, causing a decrease in the blood supply to other organs, which can easily lead to symptoms such as dizziness, fatigue, and palpitations. Some people may even experience low blood sugar levels, leading to hypoglycemia. This is due to temporary dysfunction of the autonomic nervous system, which inhibits the breakdown and heterogenesis of glycogen in the liver. If there were already coronary heart disease, things would be even worse. In a blood fight, it is easy to have insufficient myocardial blood supply, leading to angina or myocardial infarction.

Not suitable for bathing after sexual activity

Why? Because sexual activity is a more intense physical exertion. During sexual intercourse, there is a significant increase in blood flow to the muscles and sexual organs, and the heart rate increases. After sexual intercourse, although the blood flow and accelerated heart rate may slow down, they will still maintain for a longer period of time. If you take a shower immediately after sexual intercourse, it will inevitably increase the blood supply flow to the skin and muscles. This leads to a decrease in the blood supply to other important organs. If the blood supply to the heart and brain is reduced, it will affect their normal physiological functions, leading to transient hypotension and cerebral anemia symptoms, especially for those with cardiovascular diseases such as hypertension, coronary heart disease, and anemia. After sexual activity, immediate hot baths should be avoided. Otherwise, serious consequences may occur.

In addition, hot water immersion can also lead to male infertility. There are reports that soaking in hot water for 1 hour can damage male fertility for up to 6 weeks. Someone has conducted an experiment in which men sat in a bathtub with a water temperature of 38 ℃ for 1 hour, and after 36 hours, their semen was taken out for examination. It was found that the number and penetration of sperm decreased, but the maximum impact did not appear until 4 weeks later. This experiment also proved that immature sperm can be damaged by high pressure, and newly produced sperm takes 7 weeks to mature and transfer to the seminal vesicle, and its recovery also takes 7 weeks. Therefore, I advise friends not to have sex before and after taking a shower.
