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 medium and the potential impact high. Drink enough fluids, avoid physical exertion and direct sun during midday heat, and keep living spaces cool by ventilating during cooler hours and shading them during the day.

What to do now

Check on vulnerable people around you now, ensure sufficient water supplies, and observe any outdoor fire bans currently in place.
