The physiotherapy and health effects of crystal can be understood from the following aspects in terms of modern science: First, natural crystal has a special "piezoelectric effect." The defect-free crystal single crystal is processed into a jewelry to wear the human body, and the friction with the human body can generate a weak electromagnetic field. This electromagnetic field has a stable mood, promotes the concentration of energy, reduces the pain and tension of the patient, and accelerates the healing speed. For example, the "Crystal Therapy" advocated by the American Research Center is to press the crystal on the patient's injury to play an auxiliary treatment role. Second, from the optical characteristics of the crystal, the crystal is a one-axis crystal of the trigonal crystal, and has three optical axes. When the honing is performed by the azimuth precision, the optical axis tends to have a certain concentrating and concentrating function. When it stimulates a certain acupuncture point of the human body, it can produce certain physiotherapy effects. It is reported in foreign countries that the use of crystal to treat children's fractures, breast cancer, etc. Third, from the point of view of biogeochemistry, crystal, like other gemstones, is formed in a special geological structure environment, containing some trace elements beneficial to the human body, such as iron, copper, manganese, qing, zinc, nickel, diamond, selenium, etc. Because the smoke crystals are exposed to underground radioactive radiation, they retain a small amount of radioactive elements (very small amount, which is not harmful to the human body, but similar to radiation therapy). These trace elements are immersed along the pores and sweat glands by frequent friction with the human body. Into the human body to promote the balance of trace elements in the body, so that the body part is more coordinated. Coveralls typically provide 360-degree protection because they are designed to cover the whole body, including the back and lower legs, and sometimes the head and feet as well. While the material and seam barrier properties are essential for defining the protective level, the coverage provided by the material used in the garment design, as well as certain features including closures, will greatly affect the protective level. HCP unfamiliar with the use of coveralls must be trained and practiced in their use, prior to using during patient care. protective suit, hazmat suits, disposable coveralls SUZHOU QIANTENG GARMENTS CO., LTD. , https://www.garmentfactorychina.com
