The primary concern is the health and safety of players, referees, and other personnel who may be exposed to extreme heat during matches. High temperatures, combined with humidity and intense sunlight, can lead to heat stress, dehydration, and other serious health issues. Fans, volunteers, and staff attending games in affected cities may also face similar risks. Without adequate measures, the tournament could see disruptions, including delays or cancellations of matches, and potential long-term health impacts on participants.
