Background
The increasing frequency and intensity of extreme heat events presents a growing threat to public health, especially during mass gatherings where large numbers of people are exposed to hazardous environmental conditions. Heatwaves alone are projected to cause 1.6 million deaths by 2050, highlighting the urgency of adopting robust, evidence‑based measures to protect event attendees, especially high‑risk populations. Whether at cultural festivals, religious pilgrimages, national elections, or major sporting events, participants often face prolonged outdoor exposure and physical exertion—factors that heighten vulnerability to heat stress and related illnesses.
To address these risks, it is essential that countries and event organizers have access to practical, science‑driven tools that strengthen preparedness and response capacities. Through the Beat the Heat initiative, WHO supports the development and implementation of heat management protocols that can be applied across diverse event settings—from local community gatherings to international tournaments. These tools help organizers anticipate extreme heat conditions, implement protective measures, and respond effectively when temperatures rise, ultimately reducing adverse health impacts and building long‑term resilience.
Objectives
- To introduce practical tools for heat stress assessment, mitigation and preparedness and long-term legacy in mass gatherings
- To share country experiences using heat stress management tools for mass gatherings
- To foster a global community of practice around heat-health management at mass gatherings
