Where this comes from

Abstract

Extreme heat is a deadly but underreported health crisis that disproportionately affects vulnerable populations. This article, informed by the 2025 regional symposium Fostering Collaborations: A Symposium to Advance Equitable Heat Health Actions, identifies systemic barriers to heat resilience, including data fragmentation, siloed infrastructure planning, and a lack of rigorous evaluation for common interventions. Addressing these challenges requires a shift toward longitudinal cross-sector collaborations. Key recommendations include integrating heat-risk screening into clinical workflows, embedding thermal comfort into zoning and capital planning, and establishing formal governance roles like heat officers. By prioritizing community-driven solutions and climate justice, Massachusetts can establish a scalable national model for equitable heat health action.
