Disney rash, or exercise-induced vasculitis, is a skin reaction triggered by heat, walking, and sun exposure, commonly affecting the lower legs. It’s more prevalent in women over 50 and often occurs after long days at theme parks. Prevention involves sun protection, compression wear, hydration, and appropriate clothing choices to minimize flare-ups. Despite its nickname, Disney rash is harmless and usually resolves within a couple of weeks. Learn more about the causes, symptoms, and preventive measures for this condition.
