Far-infrared antibacterial technology has the function of releasing negative ions. The negative ions released by this negative ion cotton have a significant effect on improving air quality and the environment, especially the health care effect of negative ions on the human body, which has become more and more popular among people. accepted. Negative ions are negatively charged oxygen molecules. In the medical field, negative ions are confirmed to be an effective means of killing germs and purifying the air. The main mechanism is that after negative ions combine with bacteria, the bacteria will undergo structural changes or energy transfer, causing the bacteria to die and eventually sink to the ground. Medical research shows that negatively charged particles in the air increase the oxygen content in the blood, which is beneficial to the transport, absorption and utilization of blood oxygen. It has the effect of promoting human metabolism, improving human immunity, enhancing human muscle energy, and regulating body functional balance. According to research, negative ions have inhibitory, alleviating and auxiliary therapeutic effects on 7 systems of the human body and nearly 30 kinds of diseases, especially the health care effect of the human body is more obvious. Negative ions are called "air vitamins" in the medical community.
