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 medium, impact high. Drink enough, avoid the midday heat and physical exertion outdoors, and keep living spaces cool by ventilating during cooler hours and shading during the day.
What to do now
Check on vulnerable people around you now, ensure an adequate supply of drinking water, and observe any outdoor fire bans in place.
