Heatwave prompts worldwide advice on staying cool and safe

Rising temperatures across Europe and beyond are triggering a surge of practical guidance on coping with heatwaves. Health experts warn that hot nights can disrupt sleep, recommending strategies such as avoiding direct fan drafts, using cool pillowcases, limiting caffeine, and eating light, water‑rich meals. Veterinarians alert pet owners that pouring ice‑cold water on dogs can cause dangerous shocks, advising gradual cooling with room‑temperature water and shade. Building specialists stress the importance of effective window shading, automated sun‑screens, and proper ventilation to reduce indoor heat, while roof‑insulation experts highlight how inadequate attic insulation can turn top‑floor rooms into saunas and recommend improved insulation and reflective roofing. Homeowners are urged to maintain air‑conditioning units—regular filter cleaning, external unit clearance, and avoiding concurrent heat‑producing appliances—to keep energy use down. Additional tips include using fans aimed at the ceiling rather than directly at the body, night‑time window opening, and employing portable cooling devices such as fans and evaporative pads. Collectively, the advice aims to protect sleep quality, health, pets, and energy consumption during increasingly frequent heat spikes.
