The side effects of negative ion air purifiers on human health

The working principle of the air purifier. This product can effectively kill harmful bacteria, mold, cold viruses, tuberculosis bacteria, E. coli, infectious viruses, and suppress the invasion of pathogens; it can also eliminate and absorb toxic gases such as benzene, carbon monoxide, sulfurous acid, and methane. The core of this product is to create a "vacuum" free of bacteria and viruses for you, effectively reducing the probability of contracting infectious diseases in the space that does not circulate in the air, truly allowing you to experience a safe and pleasant feeling like in spring breeze.
Polluted air is removed or adsorbed by the air filter inside the machine, and then the air is continuously ionized by the negative ion generator installed at the outlet, generating many negative ions, which are sent out by the micro fan to form a negative ion airflow, achieving the purpose of cleaning and purifying the air. Then it provides a similar environment of fresh air in nature.
Negative ions have the effects of calming, inducing sleep, relieving pain, relieving cough, relieving itching, promoting diuresis, increasing appetite, and lowering blood pressure. For example, after a thunderstorm, the negative ions in the air increase, and people feel a refreshed mood. However, in an air-conditioned room, since the negative ions in the air are almost completely lost after passing through a series of air conditioning purification processes and long ventilation pipes, people who stay in it for a long time will feel chest tightness, dizziness, fatigue, and a decline in work efficiency and health condition, which is called "air conditioning syndrome". Air is composed of many molecules. Due to the influence of cosmic rays, ultraviolet rays, and radioactive substances in the soil and air, some air molecules release electrons. Under normal atmospheric pressure, the released electrons quickly combine with neutral molecules in the air to become negative ions, or called anions. Negative ions are a kind of negatively charged gas ion in the air. Some people call negative ions "air vitamins" and believe that they, like food vitamins, have a very important impact on the life activities of the human body and other living organisms. Some even believe that negative air ions are related to longevity and call them "longevity ions". The amount of negative ions in the air varies depending on the specific geographical conditions. They are more abundant in parks, suburban fields, beaches, lakes, waterfalls, and forest areas. Therefore, when you enter these places, your mind is fresh, breathing is smooth and clear, and you feel refreshed. Entering a crowded and congested crowd or entering an air-conditioned room makes you feel hot, breathless, etc.
The therapeutic effects of negative ion air purifiers on 7 diseases:
(1) Eliminating smoke and dust: Negative ions can quickly neutralize the positive ions such as smoke, "second-hand smoke", cooking fumes, and floating dust in the air.
(2) Improving air structure: Humans need 1.3 billion negative ions per day, but the environment such as our homes, workplaces, and entertainment venues can only provide about 2-20 billion negative ions. This often leads to respiratory diseases such as pneumonia and bronchitis.
(3) Improving lung function: After inhaling negative ions for 30 minutes, the lungs can increase oxygen absorption by 20% and release 14.5% more carbon dioxide.
(4) Improving heart function: There is a significant blood pressure-lowering effect, which can make people feel more energetic. It also improves work efficiency.
(5) Promoting renewal: Negative ions can slightly activate various enzymes in the body, promote renewal, and improve sleep.
(6) Enhancing the body's disease resistance: Negative ions can improve the responsiveness of the body and enhance the body's disease resistance.
(7) Negative air ions can alleviate symptoms such as allergic pollen fever, bronchial asthma, and upper respiratory tract inflammation.
The main effects of negative ions on the human body
There are the following effects: They affect the nervous system, which can strengthen the functions of the cerebral cortex and brain activity, make people feel energetic, improve work efficiency, and improve sleep quality.
Negative ions can also strengthen the oxidation process of the brain structure, allowing the brain structure to obtain more oxygen. They affect the cardiovascular system.
According to expert investigations, negative ions have a significant effect of expanding blood vessels, which can prevent arterial spasms and achieve the goal of lowering blood pressure. Negative ions also have great advantages in improving heart function and improving myocardial nutrition, which is beneficial for the recovery of patients with hypertension and cardiovascular diseases. It affects the blood system. Research has proved that negative ions have the effect of slowing down blood flow and prolonging the clotting time, which can increase the oxygen content in the blood, facilitating the transportation, absorption and utilization of oxygen.
The impact of negative ions on the respiratory system is the most significant. This is because negative ions enter the human body through the respiratory tract, and they can increase a person's lung capacity. Previously, experiments have shown that inhaling air negative ions for 30 minutes in a glass mask can increase the oxygen absorption in the lungs by 2% and increase the exhaled carbon dioxide by 14.5%. Therefore, negative ions have the effect of improving and increasing lung function. Because negative ions are very beneficial to human health, to address the issue of reduced negative ions when using air conditioners, air conditioner developers have developed negative ion generators, allowing people to enjoy freely absorbing "air vitamins" at home.
