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. Use the guide on protection against heat and drought to prepare.

What to do now

Drink enough fluids, avoid midday heat and physical exertion outdoors. Keep living spaces cool by ventilating in the morning and shading during the day. Look after vulnerable people nearby and observe current fire bans.
