2026 World Cup: controversy over ban on reusable water bottles in stadiums

FIFA has banned supporters from bringing reusable water bottles into stadiums for the 2026 World Cup, changing its code of conduct that previously allowed empty transparent bottles up to one liter. The decision raises concerns as the tournament will be held in summer in the United States, Canada, and Mexico, where extreme heat could endanger fans. Climate scientists and sports scientists warn that conditions measured by the wet-bulb globe temperature index increase the risk of heat-related illnesses.
