Our hectic society gives us little or no rest, so we often get overworked and overtired. Since the 21st century, forest therapy has been prescribed as a medicine for city dwellers to deal with stress and other “diseases” of a modern fast-paced society.
When the Japanese went to forests in the early 1980s, there wasn’t much scientific evidence about the benefits, but the people just felt intuitively that it was good for them.
The term forest bath or “shinrin yoku” was invented in 1982 by the Japanese agency of agriculture, forestry and fisheries, because “the Japanese needed the healing powers of nature”, and it was also part of a campaign to protect the forests. Since then, more scientific and medical research has been carried out. At first, they thought that the positive effects on sleep and stress came from the fresh air, or perhaps the effect of the colour green, but they found that forests with a high content of phytoncides in particular had very healing powers. Trees produce these oils to repel insects and other enemies, but it has an opposite effect on the human body.
reduces blood pressure and lowers stress
improves cardiovascular and metabolic health
is good for depression
boosts the immune system, increases anti-cancer protein production
improves your concentration and memory
even helps you to lose weight
The good news is that even a two-hour forest pool is enough. Not only the Japanese proved that. Recently the British published the same result that two hours/week would significantly increase your mental and physical healthy. In Scotland, doctors can already prescribe you to do a couple of days of retreat. Even the Duchess of Cambridge is since May an ambassador of forest therapy.
Better relationship with yourself and nature
As an environmental engineer with research interests in eco-psychology, I am also happy that forest therapy is taking root. Not only has it so many benefits for humans, but also for society and planet, as trees and forests have an important role, not only in climate change, but also in water balance, avoiding erosion and landslide dangers, and so on. For me, forest therapy helps to restore the relationship between nature and humans, especially city dwellers. Often the relationship comes from one way: we take from nature and dump our waste. We take it too much for granted. The same is also about ourselves. The modern society also let us neglect ourselves. Forest therapy is for me then a way to restore, or improve, the relationship with yourself and nature, which will result in a more healthy and satisfied life.
A Forest bath in Motosu-shi
Last Sunday, with the help of my friends of the Nagoya-located yoga studio Mind.Body.Space I organised a bilingual expedition to one of the certified forest therapy bases in Japan: we brought 20 other participants with us to Motosu-shi. There, a professional guide gave us a scientific and medical introduction on the effect of phytoncides on our hormones and nerves. The consultation consists of two measurements. Our blood pressure and heart rate were measured and they also took a sample of our saliva (amylase).
During a forest bath you will detach yourself from the outside world so that you can put all your energy into yourself and open up all your five senses to your immediate surroundings and to the present, so we asked everyone to leave their phones in a space provided by the consultation center. I was the only one who took a camera, partly because some participants were nervous that “they could not take photographs”.
The walk in the woods lasted an hour and a half and I think we only walked a kilometre. We took many breaks. The guide let us touch springs and snake-like plants, or smell pine needles. He pointed out the fluctuations in nature and said that people are especially calmer if they can synchronize their own fluctuations, such as blood pressure, with those of nature. It rained a little, so that the moss and ferns were beautifully green. We also often listened to what nature had to tell us.
We concluded with yoga in the open air. The water that seeped from the tree to my bare shoulders and the wind breeze made me feel completely at ease. I was in heaven. Afterwards our stress was again measured; many had booked progress and everyone returned back home with a big smile.
Above all, choose “your” forest. Once you’ve found your place, go there often. Build an intimate bond with the place. Watch carefully how the place changes during the year.
Don’t just go slow, don’t run or jog. Walking, jogging, Nordic walking… may be good for you, but forest bathing is something else. Stroll, focus on nature, sit down with your back leaning against a tree trunk, and observe what you hear, see, smell and feel.
Invest enough time and the right time in forest bath. The absolute minimum duration for a forest bath is ten minutes. Try to have minimum two hours in total every week. A forest bath is at its best at sunrise or sunset.
You shall not peek at your mobile phone. Take only what you need. If your cell phone is part of it, turn off the sound and put it in your pocket. Don’t take pictures.
Don’t think, open up your senses. Breathe in and out slowly and deeply.
Never do what’s uncomfortable.
Celebrate dreaming and fantasizing and don’t hold back.
A note about taking photographs: As you noticed, I took my camera to the forest bath in Motosu, for the reason that other participants wanted memories (and were a bit nervous when they heard to leave their phones behind), and also for own promotional materials. Although I started with the lowest stress levels (which I attribute to the fact that I was trekking and camping in Japan’s biggest national park the week before), I saw an increase in stress after the forest bath. I was maybe the only one who did not progress. I was not immersed enough, as I was trying to capture the beauty of it, instead of getting captured.

When my Norwegian friend told me about the journey of a two year old Viking heir to the Norwegian throne through mountains and forests by “birch benders” (his own translation of Birkebeinar), I was intrigued. Birch benders are a rebellious party in Norway from the 12th century which was so poor that they had to make their shoes of birch bark. By doing a bit of research I learned more about the Norwegians’ relationship to winter, the mountains and cross-country skiing and birch trees. I know in other cultures, like the Celtic and Russian, the birch has special roles and meanings, but I do not know that much about the relationship between Norwegians and the birch.
The best skiers
I learned more about the “Birkebeinerrennet” or “Birkebeiner Ski Race”, which is Norway’s most traditional cross-country ski race running every year from Rena to Lillehammer. It has been held annualy since 1932, and commemorates a trip made by the birch benders (I use the name of my friend) to save an infant which could claim the Norwegian throne, as they did not like the current Norwegian king. The two best skiers were selected to undertake this dangerous journey. All participants of the current ski race carry a backpack weighing at least 3.5 kg, symbolizing the weight of the then-one-year-old king.
The birch plays a central role in northern Norwegian life. I saw it being used for fire, but also the postwar houses are made from “this White Lady of the Wood”. So you see the birch in this picture in two forms ;). In Tromsø, I bought some tea infusion mix of black tea with birch bark .
In the region of Norway, the birch trees start to show green leafs, which is a sign that we soon can tap the healthy birch water. Birch sap is collected only at the break of winter and spring when the sap moves intensively. Birch sap collection is done by drilling a hole into its trunk and leading the sap into a container via some conduit (a tube or simply a thin twig): the sap will flow along it because of the surface tension. The wound is then plugged to minimise infection. Some years ago, a friend and I also tapped birch sap from birches in Belgium, and it was really refreshing. It is good for skin and hair. In a Norwegian book about outdoor and cuisine I found also instructions how to tap birch sap.
Back to the birch benders
As my friend explained to me a couple of times, Norwegians are mostly “humble hard working decent human without making too much of a fuzz.” Before they found all the oil reserves, Norway was not a wealthy nation and people were relatively poor and had to survive in severe conditions, being sync with the strong seasonal changes and deal with the ingredients and other resources they found in their land (which explains why their traditional meals are often simple). Birch was one of their resources, and they are very grateful for it, and learned to manage it in a resource efficient way. When people are poor, like birch binders, they can be often very innovative in finding new ways of underutilized resources like birch bark.
For me, while I witness how the temperature increase makes the snow on the tree branches heavier so the snow falls and reveals all the green, to experience the end of winter and observe spring and other new beginnings, retelling the story of birch benders is reminding us to the courage of two good skiers being resource efficient (especially now in this ecological crisis we should return to a higher use of biobased materials) to dethrone a king. For me, that king of current time is the dominating paradigm of profit-oriented of economic growth and exploitation.
Today I stumbled upon a hiking video about Mt. Tachibana in the area of Fukuoka, one of the biggest cities in Japan. The hiker highlights camphors and shows shots of tags with QR codes. The comments taught me it allows you to add the tree as a friend on Line (Asian version of WhatsApp) which brings you to a website with information and a quiz about the train, made by elementary school students. I think that is adorable.
A small note. The tree at the screenshot is not a camphor, but a cedar. A camphor looks more like this:
In Japan, camphor trees are often seen as holy trees.
Anyway, the hiking video and the idea of the QR code reminds me to an American article from 2015 about a campaign in Melbourne that a friend shared with me some weeks ago.
Let me copy paste one paragraph of this soul warming article:
Officials assigned the trees ID numbers and email addresses in 2013 as part of a program designed to make it easier for citizens to report problems like dangerous branches. The “unintended but positive consequence,” as the chair of Melbourne’s Environment Portfolio, Councillor Arron Wood, put it to me in an email, was that people did more than just report issues. They also wrote directly to the trees—everything from banal greetings and questions about current events to love letters and existential dilemmas. “The email interactions reveal the love Melburnians have for our trees,” Wood said.
Isn’t that beautiful? By the way, it is funny that the chair’s family name is Wood. In matter of fact, my family name is also derived from old Dutch for wood. It seems tree sap runs through the veins of our families for many generation 😉
Communicating with trees does not only happen in Australia. On April 1st, another friend shared the video of Google Netherlands about Google Tulip. (I have this reputation of being a tree lover, so occasionally it happens to find tree-related messages in my inbox). Google Tulip would allow us to talk with tulips.
I really loved the video, and my friend too, but she was not aware it was posted at fool’s day. However, I am very sure it is going to be the future soon. In cities in Japan, I see a lot of loneliness among elderly, and maybe it would be good to connect old men that look like trees with trees that look like old men…
If you could add one tree to become your WhatsApp or Line friend, which tree would you choose and why? Let me know in the comments.
