Recognizing and Treating Heat-Related Illnesses: A Guide

Medical experts are warning about the dangers of extreme heat and the signs of heat-related illness. The three stages of heat-related illness are heat cramps, heat exhaustion, and heat stroke. Symptoms include muscle cramps, headaches, nausea, vomiting, cool and clammy skin, elevated heart rate, and a core temperature above 105 degrees Fahrenheit. The very young and older people are most vulnerable, especially in urban environments. To prevent heat-related illness, stay hydrated, seek shade and air conditioning, and avoid caffeine and alcohol. If someone appears to have heat stroke, cool their body down, offer fluids if conscious, and call 911.
