Warm jade mattress hyperthermia, hyperthermia is a therapeutic method to strengthen blood circulation by physically stimulating human body to heat up. The principle of hyperthermia is that the head is cold and the feet are hot, that is, the physical principle of cooling down and heating up is copied to the human body. Hyperthermia, as its name implies, is warm stimulation. It is different from acupuncture because it stimulates the skin with far infrared rays to obtain the desired effect. When stimulated by warmth, our body will undergo various changes: first, the meridians will become warmer, the cold will disappear, and the qi and blood will run smoothly; Secondly, it can achieve the effect of aphrodisiac. The human body's yang is the foundation of life, so it is generally believed that yang will lead to long life, while bad yang will lead to short life. When yang is weak and yin is strong, cold syndrome will appear in human body. In severe cases, Yang Qi of yin and yang and blood will be lost in large quantities, which will endanger life. Negative ions, in the Woods, where there are waterfalls and hot springs, we will feel the fresh air, because the air is rich in negative ions. When losing atoms, they will become cations, and when gaining electrons, they will become anions. Extracting negative ions can promote cell metabolism, enhance vitality, calm the nerves, restore physical strength and enhance appetite, so negative ions are also called "air vitamins". There are about 800-2000 anions in every cubic centimeter of air. The academic research on anion and cation in the air shows that the pure air is in a stable state, and the ratio of anion and cation is 1: 1.2. However, it doesn't mean that you can sleep peacefully on the jade mattress. It doesn't matter if you are wearing jade products, but if it is a jade mattress, there are a lot of jade, such as jade, which is still very radioactive. Use with caution.
