Body Gua sha: What is it and how does it Work?
The Marks on your skin
You might have come across a photo of the results of Gua sha on the internet. They normally look something like this. This is a photo of my older brother and the aftermath of being Guashified by me while on holiday after a stressful time. I always have some tool on me that can be used whenever wherever, even on a vacation!
So the big question is, what are those nasty looking marks on his back and why does he have them there?
It kind of looks like I had a whip instead of a Gua sha tool but nevertheless that's all I had. We found some oil in the cupboard and with that as a lubricant, I just dragged the spoon across his skin with just enough pressure to pull at the tissue and muscle underneath but not enough to cause any pain.
The changes under your skin
The red marks occur because dragging a blunt object across your skin can sometimes produce changes in the tissue underneath. In order for this to happen, the tissue has to have some vascular impairment in the flow of blood through the muscles and tissue of that area. If so it can react by releasing blood cells as the vascular system in the local area improves. The red marks are where these cells have collected between the layers of your skin. The technical term for this is petechiae. And the process is very different from bruising caused by some kind of trauma.
The effect on your body
So if petechiae appears on your skin, this means that the blood flow in that area has improved but not only in that area, in others too. Connective tissue, the muscular system and the vascular system are not isolated to one area but are dynamically spread about your body. If you use Gua sha on your back for example, you are not only improving blood flow in the back area but in the body as a whole.
How the effect is organised
You could just scrape a tool over a place which has blocked tissue and get some relief. A lot of people do this, both professionally and at home, but if you really want to make a difference and really want to know what is going on, you need to delve a little deeper.
Gua sha did not just appear from nowhere. It developed over thousands of years in the Far East and there are underpinning ideas and theories which turn just scraping along your skin into an adaptable curative technique.
If you can follow the lines and muscle groups which link your connective tissue, organs and functional systems, you have hit the informational jackpot and you can start to understand how your body works.
