The prolonged and intensified heat season in Phoenix has led to a surge in heat-related illnesses, with critically ill patients making up 14% of the cases. Heat stroke, a life-threatening condition, has been a major concern. The earlier onset and extended duration of extreme heat pose significant health risks, particularly for vulnerable populations such as the elderly, outdoor workers, and those with pre-existing health conditions. Emergency services are under increased pressure to manage the growing number of cases.
