Human body odor is a natural phenomenon, and all living things will produce their own unique odor waves, which are explained by physics and chemistry as the process of substance volatilization and air reaction. Judging from your question, it should refer to the situation of heavy odor. There are two situations.

One is bromhidrosis caused by human diseases, which is also commonly known as body odor. The main symptom is that the armpit and other folded parts emit unpleasant smell, which is a disease with unique smell of human armpit secretions. Let's start with Save the Dead after Elbow. Also known as Hu Chou, underarm odor and underarm qi. Traditional Chinese medicine believes that damp-heat stagnation is caused by sweat pores, while western medicine believes that this symptom is a disease of human endocrine system and can be inherited. This symptom affects the social life of patients, and in severe cases, it can lead to psychological disorders of patients. At present, this situation can only be alleviated by surgery and drug treatment, but it cannot be cured.

The other is due to personal living habits, toxins and waste residues discharged from sweat glands are deposited on the body surface. If individuals do not pay attention to cleaning, it will cause excessive deposition and rancidity. Therefore, we should strengthen daily cleaning and develop good personal hygiene habits. Otherwise, it is not only bad smell, but also excessive accumulation of toxins and waste residue on the skin surface, which is also easy to cause lesions.

This kind of fragrant smell released from the human body is generally invisible to oneself, and only others can deeply feel it, especially the opposite sex. When these smells are mixed with sweat and secreted, the effect on the opposite sex is wonderful. The smell of human body is produced in the process of human metabolism, which is related to the substances metabolized by human body. Everyone can secrete a hormone and form their own unique physiological smell. Usually we call it body fragrance, and professionally we call it pheromone or pheromone, so everyone smells different. The body odor of men and women is obviously different, which is caused by the difference of physiological activities such as endocrine between men and women. Women's body odor will also change with physiological activities such as menstruation or ovulation. It is for this reason that the body odor emitted by adolescent men and women is attractive to the opposite sex. This has been proved by scientific experiments.
