The object of people's enthusiasm and the pursuit of people mainly lie in the role of negative ions. Air purification, recuperation and health care are two bright spots for negative ions to attract people's attention. Negative ion is a trace element in the air composition, with redundant negative charge, belonging to the "good citizens" in the air. Because most of the harmful substances in the air are positively charged, which is not good for human health, it is doomed that negative ions will become beneficial friends in people's healthy life. One of the functions of negative ions: the function of purifying air negative ions is that negative ions themselves are negatively charged, and most dust bacteria in the air are positively charged. Negative ions neutralize these dust bacteria through neutralization reaction, and then attach and settle, and fall to the ground. At the same time, negative ions use their own sterilization function to remove bacteria in the air, thus ensuring the air is clean. Negative ions do zigzag motion in the air, which is called Brownian motion for short. This unique movement mode is the best way to remove dust from the air. The most typical application and promotion of negative ions is the negative ion air purifier, which is widely used in air purification industry, such as the renovation of polluted new houses in in addition to formaldehyde, the purification of indoor kitchen lampblack, the purification of smoking smoke, the removal of electromagnetic radiation in home offices, the air purification in cars, and the air purification in some public places. , also used in medical and health purification facilities. The second function of negative ions: conditioning and health care The function of negative ions is that negative ions can easily penetrate the blood-brain barrier of human body because of their small particle size and high activity, and directly play a role by melting into blood organs in human body. Negative ions have the functions of anti-oxidation, preventing organ cells from aging, restoring alkaline human body constitution, reducing human free radicals and repairing damaged cells. At the same time, it acts on cardiovascular and cerebrovascular diseases, reduces blood viscosity, smoothes cardiovascular and cerebrovascular diseases, and effectively regulates and improves human cardiovascular and cerebrovascular systems and nervous systems. As a new favorite of health care, negative ion natural therapy is the most effective treatment method in natural therapy. The function of negative ions also lies in the treatment and care of some diseases, such as hypertension, insomnia, asthma, cancer and so on. In addition, negative ions can also improve the sub-health of human body, care for pregnant women's dizziness, insomnia and other syndromes, improve children's immunity and improve children's intelligence, and play a significant role. Negative ion physiotherapy instrument is a derivative product aiming at negative ion health care function. Fortunately, the emergence of artificial negative ions based on Senpeptide shows that.
