Perspiration, or sweating, is a natural process that works to regulate your body temperature. Underarm perspiration typically occurs in response to strenuous exercise, stress, anxiety or hot weather. It is rarely of medical significance, but it can be uncomfortable and embarrassing, especially when excessive or when it leads to unpleasant body odor. Excessive or unpredictable underarm perspiration may be a sign of hyperhidrosis, a condition that sometimes requires medical treatment.
Antiperspirants and Deodorants
Antiperspirants control underarm perspiration by temporarily blocking the sweat glands. Deodorants help control odor caused by perspiration, but they do not actually reduce the amount of sweating that occurs. Over-the-counter antiperspirants are generally strong enough to control regular underarm sweating. Dusting your underarms with cornstarch or baking soda can absorb sweat and prevent your clothes from becoming stained, and absorbent pads are available to help control perspiration, notes the International Hyperhidrosis Society.
Bathing and Hygiene
Bathe every day and more often during hot weather or after sweating excessively. Use an antibacterial cleanser under your arms if odor is an issue, and then dry yourself thoroughly when getting out of the tub or shower. Soaps that contain perfume or other chemicals can cause skin irritation that may worsen sweating and body odor instead of helping to prevent it.
Lifestyle Changes
Wear clothing made of natural fibers, such as silk and cotton, to encourage air circulation under your arms. Sleeveless shirts are beneficial, especially when exercising or spending time outdoors. Synthetic fabrics designed to pull moisture away from your skin are also useful during exercise, provided you remove them immediately after finishing your routine.
Diet and Alternative Therapies
The International Hyperhidrosis Society states that alcohol, hot beverages, caffeine and spicy foods can increase sweating. Avoiding these foods may be beneficial. St. John's Wort, chamomile, valerian root, acupuncture and hypnosis are other possible remedies for underarm sweating, and relaxation techniques such as meditation, yoga and biofeedback can help you manage stress levels and reduce perspiration, according to MayoClinic.com. Use caution when trying valerian root.
