Extreme heat poses significant risks to students, including heat-related illnesses and reduced outdoor activity safety. Florida cities like Orlando and Tampa rank among the top 10 U.S. cities with high urban heat island exposure, where densely built environments add at least 8°F (4.4°C) to temperatures. Children are particularly vulnerable due to their physiology and dependence on others. Schools are working to mitigate these risks by creating shaded and cooler environments for outdoor activities.
