Why track heat illness?

The Maine Tracking Network tracks emergency department visits and hospitalizations due to heat illness to understand how Mainers are affected by hot weather. Because spending time in air conditioning is often the best prevention against heat illness, Maine also uses survey data to track the number of homes that have air conditioning. Analysis of heat illness and air conditioning prevalence can provide a better picture of which groups of people may be more vulnerable to the effects of high heat.

This information will likely become increasingly important to public health and safety planning efforts as periods of extreme heat occur more frequently or for longer stretches of time due to climate change.
