The ongoing heatwave in Phoenix is particularly dangerous for individuals without access to cooling systems, outdoor workers, and those with pre-existing health conditions. Prolonged exposure to high temperatures can lead to severe health issues, including dehydration, heat exhaustion, and heat stroke. Vulnerable populations, such as the elderly and children, are at heightened risk. The extreme heat also increases the likelihood of power outages due to high energy demand, which could exacerbate the situation for residents relying on air conditioning.
