Leading scientists have warned FIFA that its current heat mitigation strategies for the 2026 men’s World Cup are inadequate, potentially endangering player health. The experts argue that existing protocols do not sufficiently protect athletes from the risks associated with extreme heat during matches. Their assessment raises concerns about the potential for heatstroke and other heat-related illnesses among players. The warning comes as the tournament is slated to be held across multiple North American cities, some of which are known for high temperatures. Scientists are urging FIFA to implement more robust cooling strategies and adjust match schedules to prioritize player wellbeing. The FIFA has not yet publicly responded to the scientists’ concerns, but the issue is likely to intensify as the tournament approaches.
