Rising temperatures have a negative impact not only on the microclimate, but also on health, particularly in densely built-up urban areas. The "Cool Vienna" app makes it quick and easy to find places in the middle of the heated urban jungle that provide cooling and refreshment. On a digital map you can see drinking fountains, spray showers ("summer splashes"), baths, natural bathing areas, water playgrounds and many other "cooling points" in the immediate vicinity. Interesting information on the subject of Viennese water and other cool measures (e.g. promoting facade greening) are also available and are updated on an ongoing basis.
