The extreme heat poses a serious risk of heat-related illnesses, such as heat exhaustion and heat stroke, especially for vulnerable populations like the elderly, children, and those with pre-existing health conditions. Outdoor workers and individuals engaging in physical activities are also at heightened risk. Prolonged exposure to high temperatures can lead to dehydration and other health complications.
