The extreme heat poses significant health risks, particularly for vulnerable populations such as the elderly, children, and those without access to air conditioning. Heat exhaustion and heat stroke are major concerns, and the high overnight temperatures may exacerbate health issues by limiting recovery time. Maricopa County has reported 136 heat-related deaths this year, with hundreds more under investigation. The urban heat island effect further intensifies the heat in Phoenix, making outdoor activities hazardous during peak hours.
