H.R. 5104
The Preventing HEAT Illness and Deaths Act of 2025 establishes a comprehensive federal response to extreme heat, which kills more Americans than any other weather-related disaster and disproportionately affects seniors, low-income communities, people of color, and outdoor workers. The bill creates two new entities within the National Oceanic and Atmospheric Administration—an Interagency Committee coordinating a unified heat response strategy across 16+ federal agencies and the National Integrated Heat Health Information System (NIHHIS), which will deliver heat warnings and data tailored to protect vulnerable populations. The legislation authorizes $100–$110 million annually from 2026 through 2030 for research grants on heat vulnerabilities, a study by the National Academies of Sciences to identify gaps in heat preparedness and data, and a community resilience program providing grants for projects like cooling centers and cool roofs, with at least 40% of funding directed to low-income and disadvantaged areas. The bill requires coordination among local governments, health providers, tribes, and affected communities to develop practical tools for heat preparedness and response.
