Public Health Preparedness for Extreme Heat Events

Area of Science:

• Environmental Health
• Climate Change Adaptation
• Public Health Preparedness

Background:

• Extreme heat events (EHEs) are increasing in frequency and severity due to climate change.
• Heat poses serious health risks, including acute heat illness, chronic disease exacerbation, and adverse pregnancy outcomes.
• EHEs strain health systems and critical infrastructure, highlighting the need for enhanced preparedness.

Purpose of the Study:

• To emphasize the critical need for health system investment in response to escalating heat-related mortality.
• To present heat action plans (HAPs) as a key strategy for disaster risk reduction.
• To outline the phased approach of HAP activities for effective heat event management.

Main Methods:

• Categorization of heat action plan activities into primary, secondary, and tertiary prevention strategies.
• Emphasis on the role of after-action reports and post-event evaluations for adaptive management.
• Review of existing HAP examples across various administrative scales.

Main Results:

• Heat action plans are essential for mitigating the impacts of EHEs.
• Preparedness activities are vital for reducing heat-related morbidity and mortality.
• Adaptive management through post-event evaluation enhances future EHE responses.

Conclusions:

• Climate-resilient health systems are better equipped to handle EHEs.
• Proactive disaster risk reduction through HAPs is a necessary investment.
• Continuous evaluation and adaptation of HAPs are crucial for managing climate-sensitive heat hazards.
