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 of occurrence is high and the potential impact very high. Take preventive measures against heat stress now and find out about suitable protective steps.

What to do now

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