First of all, people with poor liver function had better not shave. This is mainly because the instrument will directly contact our skin when scraping. This kind of direct contact can promote local blood circulation, and also increase the burden on our heart and liver. If people with poor liver function are scraping, it will only lead to a heavier burden on the liver.
Secondly, pregnant women had better not shave. However, many people believe that scraping has many benefits to the body, and some people like scraping. For pregnant women, be careful during pregnancy. For pregnant women, scraping may increase the chance of miscarriage. At the same time, scraping is in direct contact with our skin, which is easy to scratch the skin. It can even lead to bruises on the skin.
And don't shave when you are tired. Because in a state of fatigue, the body is very weak, and scraping will promote the blood circulation of the epidermis. However, the blood circulation between internal organs will be reduced. If scraping is carried out at this time, our bodies will be unbearable, which will not only aggravate the state of fatigue, but also lead to shock. Because the scraping method is relatively simple, some people will choose to shave at home. People who are fastidious will go to a special Chinese medicine shop to buy scraping equipment, and also buy some Chinese herbal medicines. But when scraping, we must pay attention to the scraping method, which needs us to change slowly in the process of practice. The frequency and range of scraping are determined according to our skin's tolerance. Don't blindly pursue the final effect, scrape hard.
