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. Avoid physical exertion during the midday heat, drink enough fluids, and keep living spaces cool by ventilating in the morning and at night while shading them during the day.

What to do now

Pay particular attention now to vulnerable people around you, avoid direct sun exposure, and observe any outdoor fire bans currently in force.
