Observe the varied shades of green.” “Close your eyes and take in the sounds of nature.” “Notice the movement of the leaves.” “Touch a tree as fully as you feel comfortable and embrace it as a fellow being.” 

On a temperate weekend morning in the UCLA Botanical Garden, Sylvie Rokab, a forest bathing guide, led a group of healthcare professionals, including myself, in using the senses to connect with nature. The guided experience was peaceful and educational; the ability to move through natural settings more mindfully and intentionally has since become something that I have maintained. These are some basic elements of shinrin-yoku, the Japanese art of forest bathing, and the experience in the UCLA garden was proof that one doesn’t need to be in a vast woodland to reframe one’s relationship with nature. 

It’s clear to most of us that Western society’s relationship with nature needs revamping, with humans increasingly separated from nature due to factors such as widespread urbanization and most children favoring electronic devices over playing outdoors, resulting in an “extinction of experience”. In a recently published study,1 Miles Richardson, a researcher at the University of Derby, cleverly used the frequency of nature-related words in books published since the 1800s to demonstrate a 60% decline in nature-connectedness over time. Earlier, Richard Louv, in his popular 2005 bestseller “Last Child in the Woods”, coined the term “nature-deficit disorder,” reflecting the change in children’s play relationships with nature. In parallel with our separation from the natural world, Western thinking has embraced individualism, materialism, and human exceptionalism (seeing ourselves as distinct and more important non-human elements of nature).

This separation from nature is not universal and has not always been so pervasive. Numerous Indigenous cultures place deeper importance on the relationship with nature. One particularly interesting study2 of First Nations elders in Canada was conducted by Dr. Nicole Redvers of the University of Western Ontario. Some elements of the nature relationship included (some common to numerous North American Indigenous nations) primacy of law coming from nature rather than from people, the inseparability of the health of nature from the health of all species including humans, and recognition of deep inter-connectedness between people and all things of nature (“the plants, rivers, lakes, wind, are all our relatives out there”). Many cultures across the world are more nature-connected than we are, with deeper connection to the land and environment, rich relationships and knowledge of plant medicines and plant allies, a relational approach to environmental stewardship, and recognition that human intelligence is far from the only intelligence out there. There is a wholeness and depth in the natural world, a sense of the sacred, and an understanding of the importance of reciprocity and land stewardship that Western societies have lost.

Western science is beginning to catch on to the benefits of nature connection. Spending time in nature improves physical health, mental health, and general well-being. While the evidence is difficult to dispute, science still doesn’t agree on why being in nature has a positive effect on human well-being. One of the more popular theories, Attention Restoration Theory, was devised by Rachel and Stephen Kaplan in the 1980s. It suggests that being in nature shifts our psychological state to a more effortless mode of attention, lessening the noise bombarding our brain’s attentional system, improving our cognitive functioning, and promoting feelings of calm. Roger Ulrich, famous for demonstrating that hospital patients with views of green spaces recover more quickly from surgery, coined the Stress Recovery Theory, which suggests that nature provides a restorative environment that aids in recovery from emotional and physiological stresses. E.O. Wilson, the evolutionary biologist most famous for his work on group behavior of insects and sociobiology, popularized the term “biophilia” and suggested that humans have a deeply innate affinity for life and the natural world. Another clue to why nature is so beneficial may come from the study of awe, the emotion of reverence and wonder. Dacher Keltner, UC Berkeley’s researcher and world’s expert on awe, notes that the experience of awe is common to both meaningful experiences in nature and to psychedelic experiences.

The current era of Western history may be reaching a watershed moment, as many simultaneous movements aiming to realign our relationship with nature are taking root. To list just a few examples: Japan and South Korea have led other nations in encouraging a national practice of forest bathing (shinrin-yoku) by public campaigns, physician training, and establishing public forest bathing paths within the national park systems. Architecture is starting to incorporate features of biophilic design, an approach that uses nature-inspired design to mimic or integrate natural elements to foster nature connection. Schools are increasingly building green playgrounds with the aim to improve childhood development and attention in school. The number of grassroots and advocacy movements at local and national levels is growing rapidly. If you live in a medium to large city, you have a good chance of seeing urban farms, community gardens, urban greening movements, environmental justice groups, and maybe even a group belonging to the rewilding humans movement

Within healthcare and scientific research, in addition to established movements such as One Health and Planetary Health, a newer movement emerging from UC Los Angeles is the Ecological Medicine movement.3 Founded by Helena Hansen, Professor and Chair of Psychiatry, and Landon Pollack, entrepreneur and philanthropist, it is an approach that hopes to counter the trend toward individualism and reductionism in medicine and science. Instead, it argues that understanding the full spectrum of human health requires understanding people’s connections to themselves, to others, to other forms of life, and to the wider environment. In short, health is dependent on inter-connectivity, inter-dependency, and relationality, not just the evaluation of a person in isolation. Two important components are: 1) a better understanding of inter-connectivity and wholeness, inspired and informed by Indigenous wisdom, and 2) bringing nature-based interventions into the healthcare system.

There are many paths toward nature-connectedness, such as forest bathing, companion animals and animal-assisted therapy, gardening, urban farming, time spent in parks and other natural settings, and even virtual reality nature experiences (just to name a few). Nature connectedness is built on a foundation of actively noticing and engaging with nature, rather than more passive or superficial interactions. As integral ecologist and nature connectedness researcher, Matthew Zylstra has stated: “it’s not just contact with nature, but the nature of the contact.” A particularly ancient and powerful path to nature-connectedness comes through the use of psychedelic plants and fungi. Western cultures are beginning to find in Indigenous knowledge rituals and meaning that are missing in their own cultures. The resulting mixing of Westerners and Indigenous knowledge keepers has brought traditional plant and fungal medicine rituals of ayahuasca, mushrooms, and peyote to the West, along with both benefits and harms resulting from this cultural exchange. The West has learned that these psychedelic agents can elicit encounters with the sacred or mystical, contact with nature entities and spirits, and an enhanced sense of connectedness to others or the environment. Some of these experiences encompass elements of animism, a belief system present for most of human history’s relationship with natural world – with a repertoire of greater sacred reverence for the aliveness of all things. It is notable that historical use of psychedelic rituals has been outdoors or in settings with more nature contact (as well as largely being in group settings), perhaps optimized to harness the power of psychedelic medicines to improve relationships with the community and the land (as opposed to the common Western model of individual sessions in closed spaces). There has been research on the power of psychedelic experiences to promote nature-connection, but the field is still in its infancy. 

Sam Gandy, an ecologist and psychedelic researcher, is one of the foremost experts in the field4,5. According to Dr. Gandy, a single psychedelic experience is potentially capable of eliciting a rapid and robust increase in nature-connectedness. He also notes that such shifts may be more likely when psychedelics are used in nature-based settings, and there are commonalities between meaningful experiences in nature and psychedelic experiences, such as experiencing awe, occasioning mystical experiences, and loosening the boundaries of the self and readjusting our sense of identity in relation to the natural world. Though more research is needed, an enticing proposition is whether psychedelic experiences might translate into greater pro-environmental behavior. In essence, nature-based reconnection and reciprocity with the land could be viewed as mutual healing and a road to planetary stewardship.

There is reason for hope that despite the planetary crisis, more people are recognizing the urgent importance of reconceptualizing how we interact with nature. A multitude of movements are being fueled by the ethos that our collective health depends on reframing and prioritizing our relationship with nature in a meaningful way. While the “discovery” of the benefits of nature-based interventions in healthcare and the power of psychedelic experiences to connect us to nature are important, they are, in fact, rediscoveries of long-held Indigenous wisdom that has been largely overlooked by Western science. Deeper connection to nature, with humility and reverence, and a renewed sense of stewardship come from this wisdom, along with a sense of rejoining of humanity with the rest of nature (the more than human).  There are ecological and environmental wounds and injustices that need healing, and perhaps what we learn from nature-connection, Indigenous wisdom, and psychedelic plants and fungi might help us on the right path of human and planetary health. This may help usher in a shift in perspective, where we see ourselves as existing as a part of nature, instead of apart from nature.

It is apt to conclude with the words of Albert Hofmann, the Swiss chemist and discoverer of LSD, who felt that the capacity of psychedelics to reconnect our species with the natural world was their most fundamental role. Shortly before his death, at the mighty age of 101, he said: “alienation from nature and the loss of the experience of being part of the living creation is the greatest tragedy of our materialistic era. It is the causative reason for ecological devastation and climate change. Therefore, I attribute absolute highest importance to consciousness-change. I regard psychedelics as catalyzers for this.”
