My mother had many minor health problems when she was old. For example, when I was young, my back and cervical spine suffered a lot. Now I feel pain when I am tired. Every time the pain comes up, we will rub her and hit her. Once, I overheard someone say that sea salt hot compress can promote blood circulation and remove blood stasis. I thought at that time that the salt eaten at home also has the function of sterilization and anti-inflammation. Sea salt should be more effective. So I bought one online and tried it on her. I bought the kind that can cover the whole back. When I opened it, it smelled of Chinese medicine. My mother said that when the salt bag gets warm, the pain in my shoulders and back will be relieved, and I feel very warm and comfortable. I think its principle is that as the heat of salt gradually increases, the Chinese medicine mixed in it will gradually infiltrate and achieve the effect of physical therapy. Later, I was idle and used it several times. It's very comfortable and relaxed after painting. But it is only a temporary relief, and it cannot be eradicated.
The body is the capital of the revolution. You should not be too brave in everything. It is best to keep in good health from an early age.
