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 considered medium and the potential impact high. Avoid physical exertion during the midday heat and pay particular attention to vulnerable people around you. Keep living spaces cool by ventilating in the early morning and at night, then shading windows during the day.

What to do now

Drink enough fluids, avoid outdoor exertion during the hottest hours and observe any outdoor fire bans in effect. Consult the linked guide on protection from heat and drought to prepare effectively.
