The extreme temperatures pose significant health risks for both players, who face exertional heat illness and impaired performance, and tens of thousands of fans, particularly those consuming alcohol, with warnings of potential heat-related incidents. Scientists have criticised Fifa's current heat safety guidelines as 'inadequate' and 'impossible to justify,' noting that the global temperature increase due to climate change has intensified and made such heatwaves more frequent, linking the current conditions to a 1.26 F (0.7 C) warming since the US last hosted the World Cup. Experts explain that heat impacts athletes by making it harder for their bodies to cool down internally and externally, with intense exertion in scorching conditions leading to severe fatigue, impaired decision-making, and potentially exertional heat stroke, the third leading cause of death among athletes. Despite Fifa's protocols like hydration breaks and limiting outdoor matches, medical professionals and players' unions, including Fifpro, advocate for stricter measures, such as delaying matches at a lower threshold of 82.40 F (28 C), while teams employ strategies like acclimatisation and focusing on technical play to mitigate heat stress.
