At least 3% of the global population suffers from excessive sweating, aka hyperhidrosis. How many people is 3% you ask? 211,410,000! That's right: more than 211 MILLION people. They may be sweating on different body areas, or for different reasons. But they are all dealing with excessive sweating and so do we.

The International Hyperhidrosis Society is committed to reducing the symptoms, anxiety and social stigma associated with excessive sweating by offering education, support and medical resources to 211 million affected children, teens and adults worldwide. The IHHS supports hyperhidrosis research, educates healthcare professionals in optimal diagnosis and care, raises awareness about the condition's emotional and economic impacts, and advocates for patient access to effective treatments while increasing public understanding of this debilitating medical condition.

Be sure to browse our rich online content starting with comprehensive discussions about normal sweating, excessive sweating, and hyperhidrosis. Try out our geo-coding hyperhidrosis Physician Finder that helps anyone with excessive sweating find medical help, check out the up-to-date information on excessive sweating treatment options, and check out our in-depth collection of hyperhidrosis insurance and reimbursement tools, including downloadable forms, which helps sufferers work with their physicians and health insurance plans to get the correct coverage for necessary treatments. There are practical tips to make the most out of appointments with physicians, information on hyperhidrosis clinical trials and a free e-newsletter, SweatSolutions that keeps our 50,000+ subscribers current on hyperhidrosis news and medical breakthroughs. And because hyperhidrosis usually starts in the teen years, the IHHS has created an award-winning teen workbook, Know Sweat Now, and launched a nationwide Know Sweat in School campaign specifically for school nurses.
