🗞️ Driving the news: A new nationwide study published in JAMA Internal Medicine reveals that homeless individuals are 27 times more likely to visit emergency rooms for heat-related illnesses than the general U.S. population
• The analysis, led by physician Taylor Weckstein, used emergency department data from 2021–2022 and highlighted severe health disparities, especially in Western and Southern states
• Notably, homeless individuals were also twice as likely to be hospitalized after such visits
🔭 The context: With climate change intensifying extreme heat events, particularly in the U.S. Southwest, vulnerable populations face heightened risks
• In Maricopa County, Arizona, half of the 600 heat-related deaths in 2023 involved people experiencing homelessness
• Earlier regional studies — such as one in Las Vegas — have shown similarly disproportionate mortality rates among this demographic due to prolonged heat exposure
🌍 Why it matters for the planet: This research underscores how climate change compounds existing social vulnerabilities, highlighting a critical intersection between environmental and public health crises
• Without urgent adaptation measures — such as cooling infrastructure and affordable housing — climate change will continue to endanger lives, particularly among unhoused populations
• The findings support the call for equity-based climate resilience policies
⏭️ What's next: Researchers and public health experts urge expanded access to cooling centers, affordable housing, and medical outreach for homeless communities
• As heatwaves become more frequent and intense, local and national governments face growing pressure to incorporate vulnerable populations into climate adaptation and emergency planning
• The data may also influence future urban policy and public health funding decisions
💬 One quote: “That difference was much higher than even I expected, with some clinical experience… That felt pretty striking to me.” — Taylor Weckstein, lead author of the study
📈 One stat: Emergency department visits for heat-related illness among homeless individuals reached 604 per 100,000 people, compared to just 22 per 100,000 among the general U.S. population
