International scientists have raised renewed concerns over player safety ahead of the upcoming FIFA World Cup to be hosted across the United States, Canada and Mexico. They warn that elevated temperatures during the tournament could pose significant health risks to footballers competing in the event.
The concern follows experiences from the FIFA Club World Cup held previously in the United States, where players reportedly faced difficulties due to hot weather conditions. According to researchers, 14 out of the 16 stadiums scheduled to host World Cup matches are expected to experience potentially hazardous levels of heat. In several regions, particularly in the southern United States and northern Mexico, daytime temperatures are forecast to range between 30 and 35 degrees Celsius, with peaks approaching 40 degrees Celsius in some instances.
Scientists emphasise that temperature alone is not the only risk factor. Humidity, solar radiation and wind conditions can also combine to place additional physiological stress on players. These environmental factors can significantly affect the body’s ability to regulate heat, increasing the risk of dehydration, fatigue and heat-related illness.
The researchers have urged FIFA to adopt more effective safety measures. They argue that current guidelines are not fully aligned with modern scientific evidence. Recommendations include extended cooling breaks, clearer protocols for delaying or suspending matches in extreme weather conditions, and improved cooling facilities for players.
FIFA has already announced certain measures in response to heat concerns. Each match will include mandatory three-minute cooling breaks in both halves. In addition, climate-controlled benches will be provided for substitutes and technical staff. The governing body is also using the internationally recognised Wet Bulb Globe Temperature index to assess heat conditions during matches.
However, a group of 20 scientists believes these steps are insufficient. They propose that matches should be postponed or suspended if temperatures exceed 28 degrees Celsius. They also recommend extending cooling breaks to at least six minutes to better manage player safety under extreme conditions.
The key concerns and proposed measures can be summarised as follows:
| Aspect | Current Situation | Scientists’ Recommendation |
|---|---|---|
| Host stadiums | 14 of 16 expected to face high heat risk | Match postponement based on risk levels |
| Temperature range | 30–35°C, potentially near 40°C | Action threshold above 28°C |
| Cooling breaks | 3 minutes per half | At least 6 minutes |
| Weather protocols | Limited extreme-weather rules | Clear suspension/postponement policy |
| Player protection | Climate-controlled benches | Expanded cooling facilities |
Andrew Sims, Director of the New Weather Institute, stated that excessive heat can rapidly deteriorate players’ physical condition and therefore requires very serious consideration.
The concerns have prompted renewed discussion on whether existing heat management protocols in international football are sufficient for tournaments held in increasingly warm climatic conditions.
