Extreme heat is a silent threat whose impacts often go unnoticed until communities experience spikes in dehydration, heat stroke, kidney disease, and other illnesses. Central America and Mexico are particularly susceptible because many people live in poorly planned urban areas without access to clean water and sanitation, and high poverty levels limit adaptation options.

This page showcases preliminary analyses from our ongoing systematic review of heat stress research and interventions across Latin America. Below are country-specific analyses examining heat vulnerability, health impacts, and the populations most at risk. Each summary synthesizes available data on heat hazards and identifies critical knowledge gaps.
