Scandinavian heatwave triggers warnings on car safety and alcohol

In Norway, a test by the German automobile association ADAC showed that the temperature inside a parked car can rise to 50 °C after just 30 minutes and reach 60 °C after 1½ hours when the outside temperature is 27 °C. The Norwegian Food Safety Authority warned that children and pets left in such conditions risk heatstroke and death, urging owners to avoid leaving them in vehicles. Police advised the public to contact owners via the vehicle registration number or call emergency services if a dog is found locked inside a hot car. Some newer car models (e.g., Tesla, Polestar, Nio, Xpeng) offer systems that keep the climate running while parked, and reflective shields were shown to lower interior temperatures by about ten degrees.

Denmark’s Health Authority, responding to a heatwave with temperatures forecast up to 35 °C and high humidity, issued a "dangerous weather" alert and recommended staying in shade, drinking plenty of water, wearing hats and loose clothing, and applying sunscreen with at least SPF 30. The agency also advised the public to limit alcohol consumption, as it can increase the risk of heatstroke, and to consume salty foods to maintain electrolyte balance. The Danish Meteorological Institute elevated the heat warning to its highest level for the weekend.
