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

What to do now

Drink enough fluids and avoid the midday heat and physical exertion outdoors. Ventilate living spaces at night and in the morning, shade them during the day, check on vulnerable people nearby, and observe any outdoor fire bans in place.
