According to WebMD and the American Academy of Dermatology, ways to stop excessive sweating, or hyperhidrosis, include antiperspirants and medical treatments such as iontophoresis, Botox injections, prescription medication and surgery. At-home remedies to help relieve excessive sweating include wearing light fabrics, drying the body thoroughly before putting on antiperspirant, using liners and shoe inserts, and avoiding alcohol, spicy food and hot beverages, according to WebMD.
WebMD also reports that daily bathing with an antibacterial soap can keep odor-causing bacteria in line.
The American Academy of Dermatology says that antiperspirants, which may be prescription and of clinical strength, are normally the first treatment a doctor recommends. Patients can apply them to underarms, feet, hairline and hands. Antiperspirants function by blocking sweat glands, which tells the body to cut down on sweat production. Irritated skin is one possible side effect.
Iontophoresis is time-consuming but can be done at home, according to the American Academy of Dermatology. People submerge their hands or feet in a pan of water, and a device sends an electrical current through their bodies. Six to 10 treatments are generally enough to shut down sweat glands. Botox injections bar a chemical that kindles sweat gland production, and this treatment decreases sweating for four to six months. Prescription medicines work by temporarily suspending sweat gland function.
