94-year-old woman dies of hyperthermia in Sceaux as French heatwave intensifies

A 94-year-old resident of a top‑floor apartment in Sceaux died of hyperthermia after indoor temperatures rose above 34 °C during a recent heatwave. The woman's shutters had been removed for renovations, leaving the south‑facing flat exposed to the sun. Medical experts warn that opening shutters or windows in extreme heat can trap hot air inside, turning apartments into ovens and putting vulnerable occupants at serious risk.

In the same period, French motorists have reported accelerated yellowing of plastic car headlights due to prolonged exposure to high temperatures and UV radiation. Experts advise polishing, fine‑grit wet sanding, and applying anti‑UV sealants to restore clarity and protect the polycarbonate lenses from further degradation.

Both incidents highlight practical safety measures during heatwaves: keep external shutters fully closed when outdoor temperatures match or exceed indoor levels, and protect heat‑sensitive materials—such as vehicle optics—with UV‑blocking treatments.
