Sweating on a woman’s body with a sour odor can be solved by washing the body and clothes in time and using antiperspirant drugs. The sweat secreted by the body has some other substances besides water and there are some bacteria on the surface of the skin. If sweat stays on the surface of the skin for too long, it will react with the bacteria and then the odor of sweat will appear. So you should keep your skin clean and dry. When it is hot and sweaty, take a shower and change and wash your clothes in time. If you sweat very much, you can use antiperspirant, antiperspirant medication, talcum powder, etc. to keep your skin dry, especially pay attention to the root of your thighs, armpits and other parts of your body. If the symptoms are not relieved after lifestyle modification, you should consult a doctor and clarify the cause of the disease.
