Scientists warn Fifa’s ‘wet bulb’ temperature policy underestimates strain players undergo during matches
Footballers face a “very high risk of experiencing extreme heat stress” at 10 of the 16 stadiums that will host the next World Cup, researchers have warned, as they urge sports authorities to rethink the timing of sports events.
Hot weather and heavy exercise could force footballers to endure temperatures that feel higher than 49.5C (121.1F) in three North American countries in 2026, according to the study. It found they are most at risk of “unacceptable thermal stress” in the stadiums in Arlington and Houston, in the US, and in Monterrey, in Mexico.
