Why does taking a bath too often affect human health?

Bathing can clean the skin and promote blood circulation, which has many benefits to human health. But taking a bath too often will also affect your health. This is because the main function of skin is to protect the human body. Some secretions and metabolites of skin can form a layer of "natural protective agent" on the skin surface, which can effectively prevent the invasion of harmful substances, thus playing a role in protecting the skin and protecting the body. If bathing is too frequent, this layer of "protective agent" should be washed with warm water and soap, and some harmful substances may take advantage of it and affect human health. In addition, don't rub your skin hard when taking a shower. Rubbing the skin hard will also destroy this cortex, and germs and harmful rays will take the opportunity to enter, which will cause people's skin infection to form folliculitis and even develop into furuncle and septicemia. Therefore, when taking a bath, you should gently rub your skin, and the tender places such as elbow fossa, fu-organ fossa and perineum should be particularly light.
