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.
At the facebook page of Mind.Body.Space you can find back a photo album of our first forest therapy activity.
Some guidelines for a good DIY forest bath
- 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.
