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 considered medium and the potential impact high. Prepare now for the heat using the linked guide.

What to do now

Drink enough fluids, avoid the midday heat and physical exertion outdoors. Keep living spaces cool by ventilating during cooler hours and shading during the day. Regularly check on vulnerable people around you and observe any outdoor fire bans in effect.
