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 assessed as medium and the potential impact as high. Preparing early can significantly reduce health risks; the linked guide outlines concrete steps to take.
What to do now
Drink enough fluids and avoid physical exertion and time outdoors during the midday heat. Ventilate rooms at night and in the morning, then shade them during the day. Check on vulnerable people around you and observe any outdoor fire bans in place.
