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 assessed as medium, impact as high. Take precautions early to protect yourself and vulnerable people around you.

What to do now

Drink enough fluids, avoid physical exertion during the midday heat, and keep living spaces cool by ventilating in the morning and shading during the day. Look after vulnerable people nearby and observe current outdoor fire bans.
