Heat wave strains German workplaces, hospitals and drivers

A prolonged heat wave with temperatures above 30 °C is prompting warnings across Germany, Austria and neighbouring regions. The IG Metall union advises against using fans in shared offices because they can circulate aerosols and cause drafts, and instead recommends night‑time ventilation, blinds and shading to keep indoor temperatures down. Pharmacists warn that high temperatures can alter the effect of many prescription drugs – transdermal patches may deliver excess medication, diuretics increase dehydration risk and insulin can act faster, so patients should consult pharmacies before adjusting doses.

Automotive clubs such as the ÖAMTC and ADAC highlight the danger of hot cars, noting that interior temperatures can reach 45 °C within 15 minutes, endangering children, pets and increasing accident risk. They advise against leaving people or animals in vehicles, recommend keeping windows slightly open, using sun‑shades and, in emergencies, breaking windows to rescue occupants.

Hospitals are especially vulnerable: only about 38 % of German clinics have fully air‑conditioned patient rooms, and staff report that heat aggravates conditions such as delirium, cardiovascular strain and infections. The German Hospital Association calls for a multibillion‑euro investment programme to equip facilities with cooling systems and shading.

Employers must protect staff from heat‑related health hazards. While there is no legal right to “heat‑free” leave, regulations require measures such as providing drinking water, adjusting working hours, installing ventilation or fans, and allowing flexible or remote work where possible. Examples from North‑Rhine‑Westphalia ministries show the use of home‑office options, water stations and automatic blinds to mitigate heat stress.
