Abstract Introduction In 1839, the Lexicon Medicum mentioned the “healing powers of nature”, arguing that many illnesses could be cured without the help of medicines, simply by paying attention to air, food, rest, physical activity, and state of mind. Therefore, already then, the environment was considered therapeutic and capable of affecting the health of individuals and helping their recovery (Hickman in Therapeutic landscape. A history of English hospital gardens since 1800, 2013). This awareness has remained valid since then, although the approach has changed and evolved over time. Case description In the 20th century, these assumptions have been supported, among others, by the research carried out by Ulrich on the ability of surgical patients to recover when they were exposed to the sight of nature. Indeed, there is a growing body of research which confirms the benefits of interacting with nature in hospital settings. The results of such studies have helped to better define a new approach to design that benefits the psychophysical well-being of individuals and improves their health (i.e. biophilic design). Discussion and evaluation The aim of this article is to highlight the growing importance of a cultural change in the design of spaces aimed at reconnecting individuals with the patterns and processes of nature, both in the urban context and, in particular, in healthcare spaces. This study intends to contribute to the ongoing debate concerning a new architectural language for hospitals and to shed light on the key features of health-inducing buildings. Conclusions The global health challenges of the 21st century require a new way of thinking and a change in the organisation of healthcare services through an approach that considers human needs in their entirety, and not in a strictly therapeutic sense. According to several studies, the humanisation of healthcare spaces and contact with nature can empower the patient and have a positive impact by reducing stress and pain and improving emotional wellbeing. However, further studies are required not just in order to deepen our understanding of the human-nature relationship and its impact on health, but also to change our approach regarding patients’ health by considering a new vision of medicine, healthcare and healing environment.
