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, impact is high. Drink enough, avoid midday heat and physical exertion outdoors, and keep living spaces cool by ventilating in the morning and shading during the day. Prepare using the linked guide.

What to do now

Right now, look after vulnerable people around you, hydrate regularly, and observe any outdoor fire bans currently in place.
