Extreme Heat Tips

Extreme heat events in Minnesota are already occurring and expected to become more common, more severe, and longer-lasting as our climate changes. The following MDH tips sheet, available in multiple languages, identifies steps you can take to prevent heat-related illnesses - and how to help your families, friends, and neighbors stay safe too.

Extreme Heat Toolkit

Heat is a significant threat to public health in the United States. According to the National Oceanic and Atmospheric Administration (NOAA), heat has claimed more lives on average over the past ten years than any other severe weather event. (NOAA, National Hazard Statistics) By the end of the 21st Century, heat-related deaths could more than triple in the U.S. (NRDC, Killer Summer Heat: Projected Death Toll from Rising Temperatures in America Due to Climate Change)

The purpose of the MDH Extreme Heat Toolkit is to provide information to local governments and public health professionals about preparing for and responding to extreme heat events. Extreme heat events can cause a number of health-related problems, including an increase in deaths (mortality) and nonfatal outcomes (morbidity). Yet, almost all of the negative health outcomes from extreme heat can be prevented by taking appropriate measures to ensure that the public stays cool and hydrated during an extreme heat event.

Health, Climate Change, & Extreme Heat Training Module

The Minnesota Climate & Health Program presented a Health, Climate Change & Extreme Heat Events Training Webinar on Wednesday, August 16, 2017. As part of a six-part series focused on health and climate change issues in Minnesota, this webinar and training module covers Minnesota’s warming climate, health issues caused by extreme heat events, and strategies to prevent heat-related illnesses. The training module can be referenced as a general education tool or as a "train the trainer" module for local public health professionals.
