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, but impact is high. Take precautions now to protect your health and the people around you.

What to do now

Drink regularly, avoid physical exertion during the midday heat, and keep living spaces cool by ventilating in the morning and shading during the day. Pay particular attention to vulnerable people around you and observe current outdoor fire bans.
