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 of occurrence is high and the potential impact very high. Prepare now using the linked guide on protection against heat and drought.

What to do now

Drink enough fluids, avoid midday heat and physical exertion outdoors. Keep living spaces cool by ventilating at night and in the morning and shading them during the day. Look after vulnerable people around you and observe any outdoor fire bans in effect.
