摘要

Background

Extreme heat events are increasingly recognized as a critical global health threat, exacerbated by rising temperatures and climate change. The distribution, frequency, and health impacts of these events vary significantly across regions, posing unique challenges to public health systems worldwide.

Aim

This study aims to provide a comprehensive analysis of extreme heat events from 1900 to 2023, focusing on their geographic distribution, frequency, severity, and associated health outcomes. The objective is to equip policymakers and healthcare providers with the insights necessary to enhance preparedness and response mechanisms for future extreme heat events.

Methods

A retrospective analysis was conducted using secondary data from the International Disaster Database (EM-DAT). The study examined extreme heat events across all global regions, analyzing data on event frequency, magnitude, and health outcomes, including mortality and morbidity rates. Descriptive statistics and trend analyses were employed to identify patterns and regional disparities.

Results

The analysis revealed significant geographic disparities in the occurrence of extreme heat events, with Southern Asia (52 incidents) and Southern Europe (42 incidents) being the most affected regions. The total global mortality attributed to these events was 234,732, with the Russian Federation reporting the highest death toll (56,032 deaths). Temporal analysis identified critical spikes in mortality, particularly in 2003 (73,722 deaths) and 2010 (56,188 deaths). Countries such as Nigeria and Sudan reported the highest average heat event magnitudes (60 and 47, respectively), suggesting severe conditions, though with lower associated mortality rates.

Conclusions

This study suggests an urgent need for region-specific healthcare strategies to address the growing health impacts of extreme heat events, particularly in vulnerable regions like Southern Asia and Southern Europe. While our data indicate significant correlations, further research is needed to establish causal relationships between climate patterns and health outcomes.
