Preventing HEAT Illness and Deaths Act of 2023

This bill establishes a federal system to coordinate efforts across agencies to address health risks from extreme heat. It creates a National Integrated Heat Health Information System (NIHHIS) and an interagency committee to develop a strategic plan for heat health planning and response. The bill authorizes funding for community resilience projects that prioritize historically disadvantaged communities and those with environmental justice concerns. It mandates a study to identify gaps in heat information and response systems across the country. The legislation aims to reduce health impacts of extreme heat, particularly for vulnerable populations including the elderly, low-income communities, and communities of color.
