To prevent this health challenge, it is important to help each other to stay cool and to keep homes cool.
The municipality of Rotterdam therefore presents a new heat app: Extrema Rotterdam. In warm weather, the app tells users which health risks they are running and what they can do about them.
In hot weather, our bodies must work harder and sweat more, though it is difficult to stay cool. Without drinking enough water and seeking cooling, it is possible to overheat, become dehydrated or even die as a result of prolonged heat. The elderly, children, and people with diabetes or heart, vascular and lung conditions are particularly vulnerable to overheating and dehydration.
