Most patients are able to resume exercise within several days after miraDry treatment. Specifically, patients should wait about 48 to 72 hours before exercising. While patients may still sweat after treatment, it will be significantly reduced from the underarms. Minor side effects of miraDry include underarm swelling, redness, and tenderness lasting for several days. miraDry selectively heats and destroys underarm sweat glands, causing an immediate reduction in sweating, and decreases hair growth in the treated area. In the best-case scenario, one treatment reduces sweat by around 80% and the odor by nearly 90%. Two miraDry treatments, three months apart, almost eliminate underarm sweat for most people. It’s important to consult with your doctor if you are unsure about when to resume exercise after miraDry treatment or if you have any concerns about your health and exercise routine.
