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
The likelihood is medium and the impact high. Drink enough, avoid physical exertion outdoors during the midday heat, and keep living spaces cool by ventilating during cooler hours and shading during the day.
What to do now
Check now that vulnerable people around you are drinking enough and can access cool spaces, and observe any outdoor fire bans in place.
