Before the Mulberry tree in my garden gets its leaves each year it casts wonderful shadows on the grass. I was thinking about them when I started to read the book “Penser comme un arbe” (Think like a tree) by Jacques Tassin. He starts out by setting the evolutionary scene where we humans evolved in the trees and reflects on how much the human body is constructed using tree-like patterns. Like the one you can see in this shadow. Our circulatory system which carries the blood all around our body branches and branches just like this, splitting into ever smaller arteries and capillaries, then coming back together the way a river gathers all the streams which feed it, along ever bigger veins until it connects the blood to the heart and the lungs again.
Our lungs are like this. Branching first into left and right, then into the different lobes, down the bronchi and bronchioles to open out like bunches of grapes in the alveoli.
Trees are the lungs of the Earth, cleaning the air of pollutants, gathering up CO2 and emitting Oxygen. Interesting to think of the respiration of a person and the respiration of the planet using similar patterned structures (OK, up to a point, the trees don’t have lobes and alveoli, but their leaves provide the maximum contact with the air, just as our alveoli do that job too.)
Our lymphatic system, so crucial to our body defences uses the same “arboreal” pattern, just like the circulatory system.
Our nervous system too, with the continuously branching structures of nerves and the way each neurone in the brain reaches out to contact thousands of others.
There is something magical about our relationship with trees, isn’t there? It really does us good to be amongst them, to look at them, to contemplate them, to smell and touch them. The Japanese “forest bathing” has been studied to show the beneficial effects on our immune systems of substances emitted by the trees in the forest.
Jacques Tassin talks about studies which show the beneficial effect on children with ADHD of spending some time in the forest, and, perhaps even more surprising, the calming effects on the heart rates of people contemplating images of trees…..in other words, we get a benefit from just looking at them, even when we can’t be physically present with them.
So, I thought I’d share a few photos I took in a Cedar Forest just north of Aix en Provence.
Enjoy!
Finally, look at the tree right in the middle of this shot. The sign by the path was labelled “Candelabra Tree”.
