FIFA has introduced three-minute hydration breaks in each half of matches to protect players during the 2026 World Cup [1].
These measures address growing concerns that rising temperatures and humidity due to climate change could jeopardize athlete health. With the tournament starting this month, the intersection of high-performance sports and extreme weather has become a critical safety priority for the governing body.
A heat-risk study conducted in 2025 examined 17 locations [4]. The findings indicate that more than one-third of the matches are at high risk for dangerously hot and humid conditions [1]. These environmental stressors can lead to heat-related illnesses, affecting the physical output and safety of teams such as Brazil and Scotland.
Host cities across the U.S. are particularly vulnerable to these conditions. Locations including Miami, Houston, Dallas, and Atlanta have seen average peak temperatures reach up to 29 °C [1]. The combination of high heat and moisture creates a challenging environment for players who must maintain intense physical exertion over 90 minutes.
FIFA's decision to mandate these breaks is a direct response to the data regarding climate-driven weather patterns. By allowing players to hydrate and cool down, the organization aims to mitigate the risks associated with the sweltering conditions expected in the American South and East Coast.
While the hydration breaks provide a reprieve, the scale of the risk remains significant. The 2025 study highlighted that the geographic diversity of the host cities does not fully insulate the tournament from the broader trend of increasing global temperatures [4].
“More than one-third of the matches are at high risk for dangerously hot and humid conditions.”
The implementation of mandatory hydration breaks signals a shift in how major sporting events manage climate risk. As extreme weather becomes more frequent, FIFA is moving from reactive measures to systemic rule changes to prevent heatstroke and exhaustion. This sets a precedent for future tournaments, suggesting that climate adaptation will be as essential to tournament planning as stadium infrastructure.
