Heat-related illness hospitalizations in Minnesota:

Hospitalizations represent the most severe cases of heat-related illness. People are hospitalized for heat-related illness due to extreme symptoms, including intense dehydration, and complications from other health conditions.

Elderly and young children are more sensitive to heat and may need more care and monitoring to recover from heat-related illness. Hospitalizations due to heat are sometimes not coded as heat-related leading to underestimated counts of hospitalizations from the effects of heat.

Heat index combines temperature and humidity to better measure what the temperature feels like to the human body. On days with high temperature and humidity, we may feel hotter than expected from the termpature on its own. Heat index and heat-related illness are related, in addition to other risk factors.
