Editing Heat-related mortality rate (section)

== Observational Status ==
Monitoring of heat-related mortality rates is ongoing in many countries, supported by public health surveillance systems and environmental monitoring networks. Data availability varies geographically, with more comprehensive records in developed regions. Methodological advances continue to refine exposure assessment and attribution of mortality to heat.

Future SIGNAL releases may incorporate standardized temporal structures, enhanced geographic resolution, and integration with complementary signals such as indoor heat exposure and urban heat island metrics. Improvements in causal modeling and real-time monitoring are expected to enhance the utility of this signal for public health and climate adaptation planning.
