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 assessed as medium and potential impact as high. Drink enough fluids, avoid physical exertion outdoors during the hottest hours, and keep living spaces cool through targeted ventilation.

What to do now

Check your drinking water supplies now, plan ways to stay cool, and check in on vulnerable relatives or neighbours in the Ajoie area. Observe any outdoor fire bans currently in place.
