Effects and Benefits of Negative Ions on the Human Body
1. Improving Lung Function
Negative oxygen ions improve the cleaning efficiency of the cilia in the respiratory system. After inhaling negative oxygen ions for 30 minutes, the lungs can absorb 20% more oxygen and expel 14.5% more carbon dioxide, thereby helping to relieve discomfort in people with asthma.
2. Strengthening the Immune System
Negative ions can alter the body’s responsiveness, activate the functions of the reticuloendothelial system, and increase resistance to disease.
They can also enhance the body’s ability to eliminate toxins, help normalize hormonal imbalances, and reduce adverse reactions caused by excessive histamine, helping to prevent allergic reactions such as hay fever.
3. Lowering Blood Pressure and Supporting Cardiovascular Function
Airborne negative oxygen ions have a pronounced blood-pressure-lowering effect. They can improve heart muscle function, increase nutrient supply to the heart muscle, dilate peripheral capillaries, and raise skin temperature.
They can also increase white blood cell, red blood cell, and platelet counts; slow blood flow; increase globulin levels; raise blood pH; shorten clotting time; and increase blood viscosity.
Airborne negative ions have a noticeable therapeutic effect in people with low white blood cell counts. They also have some therapeutic effects on stage II hypertension, bronchitis, asthma, pneumonia, emphysema, coronary heart disease, cerebrovascular disease, angina, dizziness, migraines, neurasthenia, peptic ulcers, diabetes, anemia, burns, atrophic rhinitis, and upper respiratory tract infections.
4. Supporting Metabolism, Sleep, and Pain Relief
Negative ions can lower blood pressure, strengthen heart muscle function, improve sleep, and promote metabolism.
They are highly reactive and have strong oxidation–reduction effects. They can damage bacterial cell membranes or disrupt the activity of enzymes within bacterial protoplasm, producing antibacterial and bactericidal effects. They also have a pronounced pain-relieving effect.
5. Promoting Skin Regeneration and Wound Healing
Negative oxygen ions can stimulate the regeneration of the skin’s outer layer, promote wound healing, and enhance immune function.
Because they readily bind to dust, viruses, bacteria, and other airborne substances, they can remove dust and kill microorganisms, contributing to disease prevention, disinfection, and air purification.
6. Improving Alertness, Energy, and Imagination
Negative oxygen ions can improve alertness. For people engaged in strenuous work or activities that require substantial physical exertion, such as athletes, exposure to negative oxygen ions can quickly relieve fatigue and improve performance.
For people whose work is prone to errors, including typists, telephone operators, finance staff, and accountants, airborne negative oxygen ions can help maintain mental clarity and a positive mood, thereby reducing mistakes.
In sports medicine, negative oxygen ions have been used as a means of relieving fatigue and restoring physical strength, helping athletes recover more quickly after demanding exercise.
7. Supporting Sleep and Emotional Well-Being in Older Adults
Negative oxygen ions benefit sleep, mental state, and mood in older adults. They can help prevent and treat certain age-related conditions, thereby slowing aging and extending life.
In October 1991, at the 13th International Conference on Natural Medicine, Keiichi Morishita presented a report on his investigation of Bama County in Guangxi, China.
The county had a population of 224,000, including 66 people over the age of 100, with a reported centenarian rate of 30.8 per 100,000 people. At the conference, Bama was recognized as the world’s fifth longevity region.
Many factors contribute to longevity. Among the natural factors identified in Bama was an airborne negative oxygen ion concentration reaching several thousand ions per cubic centimeter. Near streams, valleys, and riverbanks, concentrations could exceed 20,000 ions per cubic centimeter. Levels were even higher after showers.
How Negative Ions Improve Air Quality
With the growing popularity of the negative ion market, people unfamiliar with negative oxygen ions may wonder what they actually do.
In simple terms, their functions fall into two main categories: improving air quality and supporting health.
Air Quality Improvement
According to the source text, research by numerous experts working in United Nations–related air and environmental protection fields has confirmed that negative ions carry a negative electrical charge.
Small ions, in particular, are highly active because of their small size and can spread freely over relatively long distances. The text describes these as equivalent to the “ecological-grade negative ions” found in nature.
Negative ions can capture fine airborne dust particles, causing them to clump together and settle. This process is described as effectively removing three categories of airborne pollution: physical particles, chemical gases, and microorganisms, creating a fresh, clean environment for breathing.
Health and Wellness Effects
Airborne negative ions have significant biological effects. They can act directly on the central nervous system and blood circulation, improve brain function, strengthen immune responses, promote metabolism, regulate nervous system function, and relieve fatigue.
The source text further describes negative ions as having beneficial therapeutic effects across seven major body systems and more than 30 diseases.
