Heat-Related Illness

As the average global temperature increases, heat waves are expected become more frequent, more intense, and longer lasting. Health problems resulting from exposure to extreme heat include heat cramps, heat exhaustion, and heat stroke. These conditions are caused by a reduction in, or collapse of, the body's ability to shed heat by circulatory changes and sweating. In especially severe cases of heat stress, death can result. The heat wave that struck Europe in the summer of 2003, claiming the lives of more than 22,000 people, is a tragic example of what may occur more regularly as global warming continues. If a heat wave of similar magnitude were to occur in the United States, heat-related deaths would surge to more than five times the current average. Already, heat waves kill more U.S. residents than any other natural disaster. The elderly, infants and children, people suffering from chronic illness, and the urban poor are especially vulnerable to heat-related illness.
