As the FIFA World Cup 2026 approaches, scheduled from June 11 to July 19 across multiple North American cities, new research from Aspetar Orthopaedic and Sports Medicine Hospital aims to address the environmental challenges that could affect players’ health and performance during the tournament. The hospital has released two research papers providing practical, evidence-based strategies to help teams manage the range of adverse conditions anticipated at the event.

The World Cup will be hosted across 16 cities, each presenting markedly different climate and environmental factors. The research highlights that players and staff will face a combination of extreme heat, altitude variations, air pollution, seasonal allergens, and the demands of long-distance travel both to the tournament and between venues. Historically high wet-bulb globe temperatures—reflecting heat stress—are expected in 14 of the 16 host cities, with six cities regularly experiencing temperatures between 30 and 35 degrees Celsius. These conditions pose significant risks to player health and on-field performance.

According to Aspetar’s reports, the intersection of these environmental stressors makes the 2026 tournament one of the most complex from a health and performance standpoint. The geographic spread means teams must tailor their preparation and in-tournament management to the specific challenges posed by each host city rather than relying on uniform strategies.

The research offers recommendations on a range of mitigation measures, including heat acclimatization protocols, hydration strategies, workload regulation, altitude adaptation, and continuous monitoring of air quality. It also emphasizes the importance of integrated travel, sleep, and recovery planning to counter the fatigue associated with frequent and extensive travel.

Prof. Marco Cardinale, Aspetar’s executive director of research and scientific support, noted that these studies reflect Aspetar’s extensive experience supporting major international sports events. He emphasized the hospital’s commitment to translating scientific research into actionable guidance, stating that safeguarding player wellbeing remains central to their mission.

In addition to Aspetar’s research, FIFA has announced a tournament-wide policy introducing three-minute cooling breaks during every match, regardless of weather conditions. This precautionary measure is intended to reduce heat-related health risks amid the expected extreme temperatures.

Teams that adopt these evidence-based guidelines and adapt their protocols to the diverse environmental conditions across host cities will be better positioned to protect their players’ health and optimize performance throughout the tournament. The findings underscore the unique challenges posed by the World Cup’s broad geographic footprint, emphasizing the need for comprehensive and flexible health and performance strategies.
