No Sweat!

Loss of the ability to sweat is known as anhidrosis. This condition is potentially life-threatening for heavily exercised horses in hot climates, but very little is known about its cause or treatment.

Acupuncture therapy is helpful in about 75% of cases, according to an article in Thoroughbred Times. This therapy may cause improvement immediately—some horses begin to sweat during the first treatment—though up to six treatments, spaced one or two weeks apart, may be necessary to resolve the problem. Unfortunately, acupuncture doesn’t help every horse, even after multiple sessions.

Other treatments used separately or in conjunction with acupuncture are dietary changes, chiropractic adjustments, and supplementation of the diet with electrolytes, beer, vinegar, flax seed, or herbal products.
