The implications of these findings are critical for the health and safety of the athletes participating in the World Cup. Playing in extreme heat significantly increases the risk of heat-related illnesses, such as heat exhaustion and heatstroke, which can be life-threatening. These conditions can also impair athletic performance, affecting the quality of the games and the overall spectator experience. Beyond the immediate health concerns for players, this research underscores a broader trend of increasing extreme weather events, particularly heatwaves, linked to climate change. Major international sporting events, which draw global attention, serve as a powerful platform to highlight these environmental challenges and the urgent need for adaptation strategies in sports infrastructure and scheduling. The safety protocols and contingency plans for the World Cup will need to be robust to mitigate these identified risks.
