Overview
- Frank Elstner, 84, has publicly warned that extreme heat can be deadly and said he fears treating dangerous summers as normal and solvable only by drinking more or using fans.
- Elstner and cardiologist Thomas Münzel announced the book Herzklima, to be published by Molino Verlag at the end of August, which the authors say examines air pollution, noise, light pollution, microplastics, chemicals, pesticides and extreme temperatures.
- According to the publisher and the authors, the book estimates about one in five cardiovascular deaths is at least partly caused by environmental exposures that raise heart risk.
- The coverage is based on a publisher announcement and interviews rather than new peer-reviewed research, and the articles report no new policy action or independent verification of the book’s numerical claims.
- The warning highlights unequal risk for the elderly, people with illnesses, children and those in poorly cooled housing and could push debate toward systemic public-health measures beyond simple personal steps.
