Started teaching in the subject "environmental psychology in landscape architecture" in 1992. In the early 2000s, a one-year master’s degree was developed. After a few years, this master's degree was extended to two years, to be in English and cover the entire area 'The importance of nature experiences and companion animals for human health and well-being'. The master program "Outdoor Environments for Health and Well-being - Master's Programme" is now run by researchers and teachers at several faculties within SLU.
Main new publications in teaching are as follows:

My research began in the mid-1980s. Together with colleagues, mainly at SLU and Lund University, four theories have been developed at the interface of landscape architecture, environmental psychology, and health sciences/medicine.
1. The overarching theory is The Scope of Meaning Theory: The theory deals with how perceived relationships to properties in the physical environment can change meaning and significance depending on the person's physical and psychological condition. Scope of Meaning is defined as a function that supports the human internal working model, i.e. how people routinely relate to the demands of the environment and their own needs (Grahn, et al 2022).
2. The Calm and Connection Theory explains how perceived relationships to features in the physical and social environment can instill security, belonging, attachment and also promote healing (Grahn et al 2021).
3. The Supportive Environment Theory deals with people's need for supportive social, physical and cultural environments. The three types of supportive environments form a mutual context. The theory is above all useful in nature-based therapy, but can also be used in, for example, architecture, landscape architecture and nursing science. The supportive environments, which are perceived through situated embodied cognition, contribute to people's health and well-being (Grahn et al 2010; Grahn et al 2022).
4. Perceived Sensory Dimensions (PSDs). Research has shown that the perceived qualities in outdoor green areas can be divided into eight perceived sensory dimensions, PSDs. The eight PSDs contain different facets of how green areas can function as health-promoting (Grahn & Stigsdotter, 2010). A weighting of all studies, conducted in Sweden and internationally, shows how the eight PSDs are related to each other and how they are associated with, for example, the size of green areas (Stoltz & Grahn, 2021). The PSDs define a holistic spatial and structural scope of action, and can function as indicators of cultural ecosystem services.
In addition to the eight PSDs, there are Nature Archetypes (Ottosson & Grahn, 2021). Unlike the PSDs, these are symbolic, existential and momentary in nature, and also include movement, season, time of day, animals, etc. The nature archetypes contain movement perception as an essential part, which is linked to vitality (Bystöm et al 2022). They are suggested to be used in nature-based therapy and can also be used to give an extra dimension to the design of environments.
Evidence-based health design and planning: In recent years, research has focused on guidelines and strategies for the design and planning of health-promoting green spaces. It is about further developing knowledge about health-promoting qualities in green areas, such as how to increase perceived safety (Sezavar et al 2023), possibility of stress reduction, especially in dense cities (Hajibeigi et al 2023; Memari et al 2021; Stoltz et al 2016; Stigsdotter et al 2017a 2017b;) rehabilitation capacity (Palsdottir et al 2018), or generally about what increases people's preference for a park (Shayestefar et al 2022). The knowledge is used to develop strategies and guidelines for how to plan and design health-promoting green areas (Bengtsson & Grahn, 2014; Grahn & Stoltz, 2022; Grahn et al 2022).
Research on the health-promoting urban green structure: Epidemiologically oriented population studies show that access to green areas is an important factor for public health (Grahn & Stigsdotter 2003). The studies have been deepened with a focus on how access to the eight PSDs affects public health (Björk et al. 2008; de Jong et al. 2012; Weimann et al. 2017; Gefenaite et al 2023).
Research on the health-promoting design of places: Research projects have investigated the health-promoting importance of green areas in preschools (Grahn et al 1997; Mårtensson et al 2009), nursing homes (Ottosson & Grahn, 2005; 2006; Bengtsson et al 2015) and workplaces (Lottrup et al 2013).
From 2002, some of the research has been conducted at a special Living Lab; Alnarp Rehabilitation Garden, where the first participants were offered rehabilitation in the summer of 2002 (Grahn, et al 2022). The research has partly focused on examining the effect of nature-based interventions, partly on increasing knowledge of how interventions should be designed. The latter deals with both the content and design of environments and the content of therapy (Währborg et al 2014; Palsdottir et al 2014; Grahn et al 2017). A similar nature based therapy has been investigated in Gothenburg (Sahlin et al 2015) and Germany (Joschko et al 2023).
Forests for recreation and stress-reducing activities. Research projects focusing on how forests can be designed to function for recreation (Stigsdotter et al 2017a; 2017b); how forests can produce forest raw materials, such as timber, and at the same time can function for recreation (Nordström et al 2015; Stoltz et al 2016); and nature-based interventions in forests (Nordh et al 2009; Høegmark et al 2021).
Animal Assisted Therapy: In 2012, a project with care farming started in Skåne. Ten so-called NUR farms, half of them with horses, were procured by Region Skåne (Palsdottir et al 2015). The intention is to make longitudinal studies on how rehabilitation of stress-related ill health works with this type of care farming. In addition to this project, a number of other animal-assisted projects have been implemented. Horse-assisted therapy (Byström et al 2019; 2022; Palsdottir et al 2020) as well as Zoo-assisted intervention (Sahlin et al 2019).
Works with projects within the program for built environment. It is about developing indicators regarding the green structure of the built environment, in cities and their surroundings. The indicators are intended to be used for survey and analysis with the intention that the built environment can achieve Sweden's environmental quality goal "Good Built Environment" and Sweden's international commitments on urban and peri-urban environments.
