For modern medical theory, a certain effect is achieved by slapping the surface layer of the body skin. Because this is the place where capillaries and small capillaries are densely distributed, the pressure generated by flapping can temporarily contract or expand local capillaries and increase blood flow, thus promoting blood circulation, which is mainly reflected in the characteristics of rosy skin and slight uplift. In fact, the human body itself is a very complex collection. I think it is unrealistic to understand and perfect this system only by a simple method. Health preservation can be said to be a profound scientific health preservation method, which requires certain basic knowledge, systematic planning and professional guidance to achieve the effect of harmonizing qi and blood, dredging meridians and promoting blood circulation. Pat therapy? You can use some tools around you, such as fitness rackets, fitness hammers, etc. Or you can pat your head, shoulders, neck, waist, back, legs, knees and other parts with your whole palm, back or even elbow. Old people and office workers can effectively relieve pain and delay pain if they can constantly pat the above parts when walking every morning and evening? Occupational disease? The occurrence of. Rubbing and patting the waist with the palm to a certain extent will definitely have a certain health care effect, but keeping a posture for a long time will make people tired and sweat, and it will also cause stiff arm muscles, so we need to be vigilant. The effect of a certain exercise method will vary from person to person. For a few people, if you beat your waist with your hands to a certain extent every day, it may have a certain effect, but more importantly, it has its own psychological effect. This result is too subjective. It is unrealistic to say that this method can greatly promote blood circulation, or can be used to treat lumbar vertebrae or cervical spondylosis, because there is not enough scientific basis and experimental data to support it.
