Why does back massage cause sha

Being in a state of fatigue for a long time will cause symptoms of fatigue and discomfort in the shoulders and neck. The most direct way to relieve these symptoms is to do a back massage, such as the method of back massage with essential oils. The massage process is very comfortable, but some people will experience skin soreness and sha after the massage, which makes everyone very puzzled. So why does sha appear after back massage?

First, why does back massage cause sha? Sha refers to the phenomenon that red, purple, black spots or black blisters appear on the skin surface after scraping, also known as "sha marks". Scratching causes the capillaries under the skin to rupture, and the blood seeps into the skin, causing bruises. These changes in the skin may last from 1 day to several days.

Second, it is normal for the skin to turn purple after scraping the back. It can also be seen in rheumatic diseases caused by wind, cold, dampness, etc., and often cause muscle pain, soreness and discomfort. After local scraping, the skin turns purple or black.

Third, blue: blue represents wind, which can invade the skin and make it prone to allergies. Eat ginkgo. Purple: Purple represents cold and invades the superficial fascia of the joints (connecting bones). Black: Black represents dampness, which has invaded the bursa. No matter what you eat, it won’t work. Use the patting method.

Fourth, scraping is not the more painful and darker the skin becomes, the more effective it is. Many people think that the highest level of scraping must be to feel unbearable pain and to scrape the skin "terribly". Experts say that this is actually a wrong view. Gua Sha is not necessarily more effective the more painful it is, nor is it better if the skin turns black and purple. In fact, you can stop scraping when the sha appears on the area that you are scraping and turns slightly red or purple. If the scraping area and force are not properly controlled, and one only pursues the color of the scraping, it will not only be ineffective, but may also cause skin and flesh damage.

When scraping the back, you should avoid wind and keep warm. When performing scraping treatment, you should avoid wind and keep warm. When the room temperature is low, you should try to reduce the exposure of the body parts. When the temperature is high in summer, you should not do scraping near an electric fan or in places with convection wind. Because the sweat pores of the skin are opened during scraping, if the wind and cold evil are encountered, the evil qi can directly enter the body through the opened pores, which will not only affect the therapeutic effect of scraping, but also cause new diseases due to the exposure to wind and cold.
