The negative ions not only promote the synthesis and storage of vitamins in the human body, but also strengthen and activate the physiological activities of the human body, so the negative ions are also called as 'air vitamins', and the negative ions are considered to have very important influence on the life activities of the human body and other organisms like the vitamins of food, and people feel happy after thunderstorm and the negative ions in the air are increased. In the air-conditioned room, negative ions in the air almost completely disappear after being subjected to a series of air-conditioning purification treatments and a long ventilating duct, and people who stay in the air-conditioned room for a long time feel chest distress, dizziness, weakness, and decline in working efficiency and health condition, which are called as "air-conditioning syndrome". In the medical field, negative ions have been identified as an effective means for killing germs and purifying air. The mechanism is mainly that after the negative ions are combined with bacteria, the bacteria generate structural change or energy transfer, so that the bacteria die and finally sink to the ground. Medical research shows that the negatively charged particles in the air increase the oxygen content in the blood, are beneficial to blood oxygen transportation, absorption and utilization, and have the effects of promoting human metabolism, improving human immunity, enhancing human body muscle energy and regulating the function balance of the human body. According to examination, the negative ions have the effects of inhibiting, relieving and assisting in treating 7 systems of human bodies and nearly 30 diseases, and particularly have more obvious health-care effect on the human bodies.
