Extreme Heat's Health Risks: Burns, Heatstroke, and Accelerated Aging

The Dangers of Extreme Heat

• 🌡️ Extreme heat is becoming a dangerous new normal, affecting large parts of the United States and Europe.
• ⚠️ Health risks associated with prolonged high temperatures include severe burns, heatstroke, and accelerated aging.

Severe Burns from Hot Surfaces

• 🔥 Phoenix resident Robert Woolley experienced third-degree burns on 20% of his body after falling on hot rocks near his pool, which reached 116 degrees Fahrenheit.
• 🏥 Surfaces like sidewalks, concrete, and asphalt can reach temperatures of 170-180 degrees Fahrenheit, causing deep burns in a fraction of a second.
• 🩺 The Arizona Burn Center sees many patients during brutal summers, with heatstroke being a significant complicating factor alongside burns.

Vulnerable Populations and Heat Illness

• 🏘️ People experiencing homelessness and substance users are at particularly high risk for heat-related deaths and illnesses.
• 💧 Organizations like Circle the City provide daily medical care, including IV hydration, to unhoused individuals suffering from dehydration and heat exhaustion.
• 📈 Despite preventative measures, Maricopa County still recorded over 600 heat-related deaths last summer.

Long-Term Health Impacts of Heat Exposure

• 🧬 New research suggests that greater exposure to extreme heat accelerates biological aging in older adults.
• 🔬 This effect, comparable to heavy smoking and drinking, can take a silent toll at the cellular and molecular level, potentially leading to future disability or disease.
• 🌡️ Chronic medical conditions can worsen for unhoused individuals as heat interacts with their medications and underlying health issues, with nighttime temperatures often failing to drop below 90 degrees.
