A key concern was the gap between recognising heat as a serious hazard and ensuring that health systems have the information, responsibilities and capacity required to act effectively.
One important challenge is accurately measuring the health impacts of extreme heat. Heat-related deaths are not always recorded as being directly caused by heat, creating gaps in mortality data and making it difficult to understand the full scale of heat-related impacts. Strengthening health information and surveillance is therefore an important part of improving heat-risk management.
The experience of Heat Action Plans demonstrated the importance of coordination across departments and institutions. Moving from general recognition of heat risk towards defined responsibilities and interventions requires collaboration between health authorities and other sectors involved in managing exposure, preparedness and response.
The presentation also placed strong emphasis on the preparedness of health facilities themselves. Extreme heat can increase pressure on emergency departments and other critical health services, making it important for facilities to anticipate increased demand. Measures such as heat-stroke clinics can strengthen the capacity to identify and manage heat-related illness.
Another key point was that a heat warning must translate into specific actions for specific actors. District health officials, surveillance teams, hospital leadership, emergency departments and community health facilities need clarity on what different heat thresholds mean for their responsibilities. This includes preparing surge capacity and strengthening reporting of heat exhaustion, heat stroke, heat stress and heat-related deaths.
Practical measures such as thermal-safety ambulances linked with cooling shelters and resilient pharmaceutical storage further demonstrated that preparedness must extend beyond forecasting and public communication. Health systems need to be operationally prepared to manage the consequences of extreme heat.
The overall takeaway was that effective heat-risk reduction requires stronger integration between early warning, health surveillance, institutional responsibilities and operational preparedness, ensuring that information about heat risk is translated into timely and practical action.
