Joachim Rathmann presents the interdisciplinary relationships between landscapes and health. Nature is to be regarded as an elementary health resource, because movement in near-natural surroundings has demonstrably positive influences on human health and is summarized in many ways in the concept of "therapeutic landscapes". Natural areas offer an important resource for strengthening health, especially to an aging society, which can also be measured economically. The author presents natural science, social science, and humanities research in a clear, understandable, and concise manner for a broad readership. At the same time he gives suggestions for a conscious handling of the sensitive resource landscape and for a regular observation of nature.
