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 medium and impact is high. Prepare using the guide on protection in heat and drought to safeguard yourself and vulnerable people around you.
What to do now
Drink enough, avoid the midday heat and physical exertion outdoors. Ventilate living spaces at night and in the morning, and shade them during the day. Check whether neighbours or relatives need help, and observe any outdoor fire bans in place.
