Researchers at the University of California, Los Angeles (UCLA) have found evidence that "sweaty palms" syndrome is genetic and not just a response to stress-related events. The findings appear in the February issue of the Journal of Vascular Surgery.
The researchers said hyperhidrosis is underreported and that as much as 5% of the US population may be affected. Previously, less than 1% of the population was thought to have hyperhidrosis and those with the syndrome were not taken seriously by the medical community, the researchers said.
