Extreme heat is increasingly disrupting the academic year for millions of American students, leading to school closures, reduced learning capacity, and health concerns. During the 2024-25 school year alone, over 9 million students across 10,000 schools nationwide experienced heat-related disruptions, signaling a growing problem with school building infrastructure not designed for current weather patterns.
Research indicates a direct correlation between classroom temperature and academic performance. Studies have shown that for every 1 degree Fahrenheit increase in school year temperature in schools without cooling, learning is reduced by approximately 1%. High temperatures, particularly those between 80 and 90 degrees Fahrenheit, are linked to increased student absenteeism and disciplinary issues. The quality of the indoor environment also impacts the spread of illness and can worsen respiratory conditions such as asthma, a significant cause of missed school days.
Younger children, whose physiological systems are still developing, are particularly vulnerable to the effects of excessive heat. These cognitive and physical challenges underscore the need for updated school facilities and effective climate control systems to ensure a conducive learning environment for all students.
