Hagen issues adhesive signage to aid in managing scorching temperatures

Cities in Germany's Ruhrgebiet Introduce Heat-Warn Stickers and Maps to Combat High Temperatures

In an effort to combat the effects of extreme heat, cities like Hagen, Dortmund, Cologne, and Düsseldorf are introducing visual aids to guide residents and visitors during heatwaves. These tools, which include stickers and maps highlighting cool places, aim to help people find relief from the heat by easily identifying accessible spots such as parks, fountains, libraries, or cooling centers.

The city of Hagen, for instance, is distributing black stickers as part of its heat protection plan. These "Heat-Warn Stickers" can be attached to smooth surfaces in apartments and other buildings. When the room temperature reaches 28 degrees, the stickers become transparent and display a red warning. Anjali Scholten, head of the health and consumer protection department of the city of Hagen, explains that high temperatures can lead to circulatory problems or shortness of breath.

Similarly, the city of Hagen is providing a "city map for hot days" to help citizens find cool places. This map shows shady locations, free water bottle filling stations, and cooled public buildings.

Other cities in the Ruhrgebiet are also adopting this approach. Dortmund, Cologne, and Düsseldorf are also providing resources to help their citizens manage high temperatures.

While the search results do not provide detailed descriptions specific to these cities’ exact use of stickers and maps for heat protection, this approach aligns with broader urban heat mitigation strategies. Municipalities often use visual aids like stickers on street signs, public transport, or shop windows and distribute maps pinpointing "cool zones" to promote awareness and improve public safety during heat events.

This concept is increasingly common in European cities affected by rising temperatures, helping vulnerable populations navigate urban heat and encouraging the use of shaded or air-conditioned locations. If you want precise examples or official documentation from these cities, I recommend checking their municipal websites or local urban climate adaptation programs, as this information is often part of official heatwave action plans or climate resilience initiatives.

On a related note, the city of Hagen is expecting up to 37 degrees on Wednesday. It is advised to stay hydrated, seek out cool places, and be aware of the potential dangers associated with high temperatures. A report on this topic will be available on 13.08.2025 on the website Radio: Local Time Ruhrgebiet.

Cities across Germany's Ruhrgebiet, such as Hagen, Dortmund, Cologne, and Düsseldorf, are promoting workplace-wellness and health-and-wellness by introducing visual aids like stickers and maps to guide residents and visitors during heatwaves, aiding them in identifying fitness-and-exercise facilities, parks, libraries, or cooling centers that can help combat the effects of extreme heat.
In addition to the Heat-Warn Stickers, Hagen City is also providing a "city map for hot days" to help citizens find locations offering cold water, shady parks, and cooled public buildings, fostering environmental-science by encouraging the use of resources for hydration and air conditioning.
As mental-health and nutrition are also crucial factors for overall wellness, citizens can benefit from maintaining a balanced diet, staying hydrated, and participating in physical activities to boost their immune systems and cope with the stress brought about by high temperatures.
Aligning with broader urban heat mitigation strategies, these visual aids like stickers on street signs, public transport, or shop windows, and maps pinpointing "cool zones" aim to raise awareness about the dangers of climate-change, specifically heatwaves, and improve public safety during such events.
To tackle the ongoing threat of climate-change and rising temperatures, cities in Germany's Ruhrgebiet are taking steps to promote health-and-wellness and environmental-science by implementing sound urban climate adaptation programs that address health, fitness, and environmental concerns.
