The extreme heat poses significant risks to players, referees, fans, and stadium workers. High temperatures combined with humidity can lead to heat illnesses, including dehydration, heat exhaustion, and even heat stroke. Historical incidents, such as a referee collapsing during a 2024 match in Kansas City, highlight the dangers. Spectators and workers, especially those in outdoor roles, are also vulnerable. Large crowds and unfamiliar environments can exacerbate risks, as seen in past heat-related tragedies at large events. Climate change is expected to worsen these conditions, with rising temperatures and more frequent heat waves increasing the likelihood of dangerous heat during the tournament.
