Many people will choose cupping for health preservation or treatment. But do you know that cupping also has some shortcomings, especially for people who often cupping? Here's a kiss with baby Bian Xiao to tell you that these things must be prevented. 1, frequent cupping can lead to skin infection. Many people think that cupping takes at least half an hour to be effective. Chinese medicine reminds that cupping actually varies according to the size, material and negative pressure of cupping. However, generally speaking, it is advisable that the time from lighting the fire, sliding the can to lifting the can should not exceed ten minutes. Because the main principle of cupping is negative pressure rather than time, if cupping takes too long under the condition of high negative pressure until the blister is pulled out, it will not only hurt the skin, but also cause skin infection. 2, taking a bath after cupping is very easy to catch a cold. You really should pay attention to order. You can cupping after taking a bath, but you must never take a bath immediately after cupping. After cupping, the skin is in a damaged state and very fragile. Bathing at this time can easily lead to skin damage and inflammation. If you take a cold bath, it is easy to catch cold because your skin is in a state of open pores. So you must not take a bath immediately after cupping. After reading the disadvantages of cupping, look at the advantages of cupping: 1. Decompression has the functions of promoting qi circulation and blood circulation, relaxing muscles and tendons, activating collaterals, relieving swelling and pain, expelling wind and removing dampness. In the self-regulation of the body, it plays a benign role in stimulating it and promoting it to return to normal function. 2, warm cupping has a warm stimulation effect on local skin, especially large cans, water tanks and medicine cans. 3. Adjust the body's balance of Yin and Yang. Due to the phenomenon of self-hemolysis after cupping, a histamine-like substance is immediately produced, which flows all over the body with body fluids, stimulates various organs, enhances their functional vitality, and is conducive to the recovery of body functions. What should we pay attention to in cupping to lose weight: it is feasible to lose weight by scraping cupping, but the cupping time should not be too long. Improper cupping may cause blisters on the body, and may also lead to accidents. In severe cases, it may lead to sepsis. Be careful. Cupping also has disadvantages. Don't think that cupping takes a long time, but it will be better if it is strong. This view is actually very unscientific. Cupping, regardless of the strength, is the most important thing.
