Where does body odor come from? Why is it called "body odor"?

In the words of common people, foxes always emit a strange smell, and if the human body secretes a lot of sweat under the armpits, it will also emit a strange smell, so this symptom is called "body odor". So, what exactly causes body odor? What factors are related to it?

1. Physiology

Smooth muscles account for a larger proportion of human body cells, and relatively speaking, women have more smooth muscles than men, so women are more susceptible to underarm odor than men. A large proportion of smooth muscles will lead to a longer time gap for cell expansion, which will eventually cause underarm odor.

2. Secretory glands

Compared with men and women, generally speaking, women have more than half more secretory glands on their body surface than men, especially in some private parts with many wrinkles, such as breasts, armpits, perineum, and umbilicus. The secretion of these glands makes the private parts of women a warm and humid environment, accelerates the growth of bacteria, and ultimately causes body odor.

3. Puberty

Clinical medical research shows that adolescent boys and girls are the most susceptible to underarm odor. This is because the bodies of adolescent boys and girls are in the development period, their endocrine system is more active than that of normal people, and their hormone secretion is more active, so they are also more likely to develop underarm odor. The symptoms of underarm odor in female patients will be significantly aggravated during menstruation and pregnancy.

4. Genetics

According to the latest medical research, underarm odor is highly hereditary. Generally speaking, if parents in a family suffer from underarm odor, the probability of their children inheriting it is 50%-80%. Therefore, heredity is also one of the important factors in the occurrence of underarm odor.
