Extreme heat becomes a health emergency through exposure, housing, working conditions, access to water, and the ability to recognise danger early.
Why it matters
A practical response connects weather alerts to schools, clinics, employers, transport providers, and neighbourhood organisations. Each needs a clear trigger and an action it can take.
Preparedness is measured by what people can do with a warning.
Public information should explain who faces the greatest risk, what symptoms require urgent help, and where support is available.
