Do negative ions exist?
Because negative ions are not visible to the naked eye, answering such questions is like answering whether there is wind, sound, or WIFI signal. The answer is yes, it exists, and it does not exist now. It has always existed in nature. It has been discovered for more than a hundred years, and people have studied its history for nearly a hundred years.
What is anion?
Staying in an airtight room in a city for a long time, people will feel dizzy. When we come to forests, seasides, waterfalls and other places, we will feel refreshed. This is the role of negative air ions. Air negative ions are also called negative oxygen ions, which are oxygen ions that are negatively charged by gaining excess electrons. It is formed by combining free electrons with oxygen molecules in the air. Natural discharge (lightning) phenomena, photoelectric effects, fountains, waterfalls, etc. can ionize the surrounding air to form negative oxygen ions. Negative oxygen ions enjoy the reputation of "air vitamin" and "longevity element" in the medical field.
What is the role of negative ions?
The role of negative ions---purify the air
Dust and dust in the air are positively charged, and negative ions themselves are negatively charged and show negatively charged. When negative ions meet particles such as dust in the air, the positive and negative phases gather, thereby condensing dust and other substances into clusters, increasing The weight of dust, etc. makes it fall on the ground. Therefore, negative ions have the effect of purifying the air. In addition, negative air ions also have the function of removing indoor decoration pollution. Air negative ions can react with residual formaldehyde and benzene after decoration pollution, and decompose them into carbon dioxide and water, thus thoroughly solving the problem of decoration pollution.
The role of negative ions---health care
Scientific research has proved that negative ions in the air have good health care effects on the human body. It directly acts on the central nervous system and blood circulation of the human body. It can improve brain function, increase immunity, promote metabolism, regulate nerve function, and eliminate fatigue. It can slow down the heart rate and normalize the blood pressure of hypertensive patients. It can also strengthen the movement of cilia on the surface of the respiratory tract, increase glandular secretion, improve the ventilation function of the lungs, and reduce the susceptibility of the respiratory tract to trauma. Air negative ions can promote wound healing, inhibit the growth of bacteria and viruses, remove air odors, and clean the air.
