Idiopathic hyperhidrosis is a physically and emotionally distressing symptom, which lacks a precise definition. Although operative and nonoperative methods have been shown to be effective in the treatment of idiopathic hyperhidrosis, limitations, cautions and complications are inherent in their extended use. The purpose of this report is to describe the theraputetic effects of magnetic resonance for managing idiopathic hyperhidrosis. A 28 years old woman had been suffering from profuse sweating on both planter and palmar sides for 15 years. We successfully treated this symptom with the 6 magnetic resonance treatments without any complications. Now she lives well in a condition of normal sweating after the applications. It suggest that short daily periods of exposure to appropriate magnetic resonance can beneficially modulate the balance of autonomic nervous system that are responsible for sympathetic overflow, and that there is an effective window of induced electrical magnetism in which sympathetic function can be controlled in the absence of side effects.
