The extreme heat poses significant health risks, particularly for vulnerable populations such as children, the elderly, and those with pre-existing health conditions. Outdoor activities during the World Cup matches, July 4 celebrations, and other events could lead to heat-related illnesses if precautions are not taken. Travel disruptions are also expected due to road closures for Taylor Swift’s wedding and other large-scale events. Prolonged exposure to high temperatures can result in dehydration, heat exhaustion, or heatstroke.
