At a Glance
- WHO has released new guidance on preventing and managing heat-related illness at mass gatherings.
- The evidence review covered studies from 1980–2025 and documented nearly half a million medical encounters, including more than 22,000 heat-related illnesses.
- WHO reports that with well-organized on-site medical systems, more than 90% of patients in studied events could be treated at the venue.
- Recommended measures include safe drinking water, cooling infrastructure, schedule changes, crowd-flow management, workforce protection, public communication, real-time surveillance and prepared on-site medical teams.
Why this matters
Mass gatherings such as sporting, religious and cultural events can amplify heat risk because of prolonged outdoor exposure, crowd density, limited access to cooling or water and pressure on local health services.
What organizers should plan
WHO recommends a whole-of-event approach covering preparation, impact mitigation and recovery. Heat planning should be integrated with venue design, crowd management, water and sanitation, transport, communications, workforce protection and emergency medical arrangements.
Clinical relevance
On-site teams should be prepared to identify and rapidly manage heat exhaustion, heat stroke, dehydration and heat-triggered worsening of chronic disease. Escalation pathways to hospitals and ambulance services should be defined before the event.
India relevance
The guidance is especially relevant for India’s large outdoor gatherings, religious events, sports events and summer public programmes. Local heat-action plans and state or district emergency protocols should remain the operational reference.
