Climate-driven heat illness threatens young athletes despite decades of prevention knowledge

A college hockey player suffered exertional heat stroke during an early morning practice in Arizona when temperatures reached the low 90s, leaving him in critical condition. Researchers have long understood how to prevent and treat heat-related illness, but inconsistent policies across schools and athletic programs continue to leave athletes vulnerable. The incident highlights how climate change is intensifying heat risks for young people engaged in physical activity.

Matthew Mayich's collapse during an Arizona State University hockey practice in August 2026 occurred when ambient temperatures were climbing toward 90 degrees Fahrenheit during an early morning session. According to accounts from his teammates, the workout extended significantly longer than initially reported and lacked standard heat safety equipment such as an immersion tub, ice supplies, and on-field temperature monitoring. Several players reported experiencing physical distress during the session, including symptoms like dropping to their knees and vomiting, before Mayich's critical episode during the final exercise.

The incident echoes a tragic precedent from 25 years prior: NFL player Korey Stringer's 2001 death from heat stroke, which elevated national awareness of heat-related athletic injuries. Despite decades of established prevention protocols and the 2010 founding of the Korey Stringer Institute at the University of Connecticut, implementation remains inconsistent across athletic programs and educational institutions nationwide.
