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 very high. Drink enough fluids, avoid physical exertion and direct sun during the midday heat, keep living spaces cool by ventilating in the cooler early morning and evening hours and shading during the day, look after vulnerable people around you, and observe any outdoor fire bans in force.

What to do now

Drink enough fluids now, shift outdoor activities to the cooler hours of the day, and check whether neighbours or relatives need support.
