What is Forest Therapy?

You may have heard of the term "forest bathing," which is a translation from the Japanese term, Shinrin-Yoku. This term originated in Japan when in the 1980's the government started to notice an increase in stress-related illness and suicide from "over-work." To combat this, investment, and research into health benefits from spending time in nature was accelerated. Scientific discoveries included the identification of chemicals produced by conifer trees, termed "phytoncides," which function not only to protect and heal the tree, but that also have statistically significant positive impacts on both human physical and mental health. The term "forest bathing," is therefore a literal reference to spending time "bathing" in the phytoncides produced by the forest - otherwise, described simply, as spending time in nature.

In practice of Forest Therapy, we are aware of the many associated health benefits of forest bathing. What we don't do as part of the practice, is quantify, or measure these. Also, helpful to know, is that we don't look at our time in nature as anything with a specific objective or outcome. We don't focus on any goals such as getting to a certain location in a certain time, as we might if we were hiking. Rather, time is spent connecting with one's senses, slowing down and noticing the More-Than-Human World (MTHW) around us, and incorporating this experience as further knowledge of ourselves and the natural world.


What does the science say?

Clearer Mind

Do you ever get negative thoughts stuck in your head? Who doesn't! This study by Bratman et al. highlights that time in a nature setting can actually interrupt and reduce thought "rumination," or the replay of negative thoughts.

Memory and Mood

Forgetful? Nature can help! This study in the Journal of Affective Disorders, showed that time in nature can lead to a significant increase memory span and capacity, as well as have a positive affect on mood.

Natural Prozac?

This meta-analysis study reviewed 28 articles on the effects of nature and Forest Therapy on depression. They concluded that "forest therapy is an emerging and effective intervention for decreasing adults’ depression levels."

Reduction in Sick Days

Nature-based therapy is now recognized as an effective treatment for stress-related illness, leading to significant decrease in both long-term disability time off from work, as well as in physician visits by employees.  

Stress Buster

The spit won't lie! Studies show that stress-related chemicals detected in saliva, including cortisol and amylase, are reduced after just 10 minutes in nature. Optimal results begin after 30 minutes and accumulate with additional time in nature. 

Immune Building

Imagine if you could influence your child's ability to fight off future disease and illness just by providing time in nature. Well, it turns out you can. Research is showing strengthened immunity in children from time in natural settings vs urban locations.

Space to grow: wilderness therapy could help abuse survivors

May 20, 2022

Wilderness therapy and access to green space may help domestic abuse survivors heal while improving therapy outcomes, a study has found.

Scientists from the University of Essex worked with the Wilderness Foundation, a charity that offers outdoor therapy programmes, to see if treatment in the natural world could work better, or alongside, traditional methods.

In its Blossom programme, which helps survivors of domestic violence, patients take part in outdoor group therapy as well as learning outdoor survival skills such as making shelter and fire and making arts and crafts from foraged materials.
