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 high and impact is very high. Prepare in advance: ensure adequate fluid intake, avoid physical exertion during the hottest hours and keep your living spaces cool.

What to do now

Drink regularly, avoid the midday heat outdoors and ventilate rooms at night and in the morning. Check on vulnerable people around you and observe any fire bans in effect.
