About this trial

In recent years, nature and forest therapy has increasingly become the focus of medical research. Recent scientific findings indicate overall positive effects of nature and forest therapy on physical and mental health. In Asia and Australia, it has already been implemented as a public health concept of prevention and health promotion. The aim of the project is to replicate the experience gained in Asia over the last three decades on the physical and psychological effects of nature/forest therapy in the context of the German forest and to investigate it further scientifically.

Treatments tested in this trial

  • Active forest therapy

  • Passive forest therapy

    Behavioral

    Participants take part in a two-hour passive clinical forest therapy in Berlin-Wannsee over two days (with a break day in between). In this setting, a trained clinical forest therapist will guide participants to various locations in the forest where participants can stay and let nature have its effect on them.
