The German Association of Dermatologists states that excessive sweating has causes related to metabolic disorders, tumors, neurological diseases, and hormonal changes during menopause, for example. The association explains that it can be addressed with antiperspirants, Botox injections to block sweat glands, regulating sweat gland activity with electrical currents, or surgically removing them. Home remedies can also help reduce sweating, such as drinking three cups of sage tea daily. Apple cider vinegar is also beneficial in reducing sweat glands; it's recommended to rub the underarms with apple cider vinegar and leave it overnight, then rinse in the morning. Additionally, wearing loose-fitting clothing made from cotton and linen helps limit sweat production. Since excessive sweating leads to loss of fluids and sodium, it's important to drink at least 1.5 liters of fluids daily, especially mineral water containing sodium.
