Heat events - prolonged periods of hot weather - cause more deaths in Minnesota than any other natural disaster. Heat-related illness encompasses many health problems: dehydration, heat stress, heat exhaustion and heat stroke. These can occur when the body becomes too hot and cannot cool down. Heat also can make worse existing chronic conditions, such as diabetes, heart disease and respiratory conditions. Health and demographic data are shown together to help identify areas where people are potentially at increased risk for heat-related illness.
