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 rated medium and the potential impact high. Keep living spaces cool by ventilating early in the morning and at night, then shading during the day. Avoid physical exertion during midday heat and observe outdoor fire bans.

What to do now

Drink enough fluids, avoid the midday heat and look after vulnerable people around you. Use the linked guide to prepare for heat and drought.
