Hot-Tub Injuries Up

Researchers have found that as the number of Americans using hot tubs has risen, hot-tub, whirlpool, and spa-related injuries have increased 160 percent in the U.S. from 1990 to 2007. Slips and falls caused half of the injuries, 15 percent were "hits and scrapes," and 11 percent were caused by heat overexposure, Reuters reports.
