Context & protective measures

Background: heat waves are becoming more frequent and intense in Switzerland. The greatest danger is the health burden from persistently high day and night temperatures, which favour dehydration, heat stroke and circulatory problems. The elderly, the chronically ill, pregnant women and infants are particularly at risk.

Recommendation

Likelihood is medium and impact is high. Prepare in advance: drink enough, avoid midday heat and physical exertion outdoors, and keep living spaces cool by ventilating during cooler hours and shading during the day.

What to do now

Check on vulnerable people around you now, keep monitoring your hydration and cooling, and observe any outdoor fire bans currently in place.
