Heat Stress Looms Large for 2026 FIFA Men’s World Cup in North America
Introduction
Footballers at the 2026 FIFA Men’s World Cup, set to be held across the United States, Canada, and Mexico, may face severe health risks from extreme heat, according to a new study published in Scientific Reports.
Climate Challenges Ahead
With venues spread across the North American continent, the study warns that significant differences in latitude, altitude, and climate will challenge players’ ability to "quickly adapt to the various local climates" (dpa reported). The tournament will take place from June 11 to July 19, 2026, during peak summer temperatures in North America.
Heat Exposure and Risks
The research, led by Marek Konefał and colleagues, reveals that 10 of the 16 World Cup stadiums will likely expose players to hazardous heat, with the highest risks found in the Texas cities of Arlington, near Dallas, and Houston, as well as in Monterrey, Mexico. Using data from the Copernicus Climate Change Service, the study simulated the climate at each venue using the Universal Thermal Climate Index (UTCI), which measures how the human body reacts to outdoor conditions.
Heat Stress and Dehydration
The results suggest that some locations could experience UTCI values exceeding 49.5 degrees Celsius, a level that poses a significant risk of heat stress. The study warns that the most intense thermal stress is expected between 2 pm and 5 pm, with UTCI values in Arlington and Houston surpassing 50 degrees Celsius in the afternoon. In Miami, peak heat stress is expected around midday. Such extreme conditions could lead to dehydration and heat-related health problems for players.
Recommendations for Match Schedules
The researchers recommend adjusting match schedules to protect players’ wellbeing during the tournament. The study assumed stadiums will not be air-conditioned; however, many US stadiums in traditionally hot places like Dallas and Atlanta do have air conditioning.
Conclusion
The 2026 FIFA Men’s World Cup in North America poses significant health risks for footballers due to extreme heat. To mitigate these risks, it is essential to adjust match schedules and consider the use of air-conditioned stadiums to ensure the safety and wellbeing of players.
