Science of Negative Ions


What is a Negative Ion?

Everything around us is made up of atoms and molecules. An atom is made up of protons, neutrons, and electrons. When there are more protons than electrons, the atom becomes a positive ion (also known as a cation) - which is bad. When there are more electrons than protons, the atom becomes a negative ion or anion - which is good.



This is an Atom. The red sphere in the center is the nucleus. The bits whirling around the nucleus are electrons.



Where can we find Negative Ions?

Any environment where there is a lot of moving water, plants, and sunlight will typically have an abundance of negative ions.

Urban environments typically have an abundance of positive ions due to air, food, and water pollution by man-made substances that the body cannot naturally process.

The ideal amount of negative ions per 1cc of air:

1,000 to 2,000 - Good for health

5,000 to 50,000 - Able to strengthen body's resistance and improve immunity

100,000 to 500,000 - Helps our body to self-heal from chronic illnesses

4 Benefits of Negative Ions

"Acidic pH levels can lead to Cancer"

1. Purifies Blood, Regulates pH & Improves Circulation

Negative ions can purify blood by increasing the oxygen capacity of red blood cells. It helps regulate the calcium ions in the blood serum to move towards the optimal level of 4mg per 100cc of blood serum. Red blood cells disperse after exposure to negative ions instead of clumping together and forming blood clots.


"Regulates our pH levels to an optimum pH level (7.35 to 7.45)" – Excerpt from “Forever Young and Beautiful”- by Dr Fumimasa Yanagisawa


In order for our bodies to remain healthy, we require a balance between positively charged ions (acid-forming) and negatively charged ions (alkaline-forming). This is referred to as pH with 1 being strongly acidic and 14 being strongly alkaline.

The higher the pH reading, the more alkaline and oxygen-rich the fluid is. This balance is critical for overall health of the body. A low pH acidifies the blood and creates excessive acid material. This acid material deposits on joints, which may lead to arthritis.

A German scientist, Dr. Guenther Ederlein’s research shows that “diseases cannot survive in an alkaline state, and yet thrives in an acidic environment.”

2. Activates Cells

When the body becomes too acidic, it will lead to excess free radicals that will oxidize the cell membrane and cause it to thicken. When it thickens, the channel for water, glucose, protein and oxygen to enter the cells may become smaller and slows down the metabolism of the cell.

Such changes can induce cell atrophy and death, hyperplasic or mutation to another type of cell, and during the transition process, may form tumor cells.

When negative ions are in contact with our cells, the passageway function of the cell membrane activates efficient transport of essential moisture, nutrients, and oxygen into cells, breaks down cytotoxins, and effects cell activation. So, when the body is rich in negative ions, which creates a mildly alkaline environment, the cells are rejuvenated and able to function better with increased oxygen intake and elimination of waste.


3. Enhances the Body’s Immune System

Negative ions can help strengthen the immune system by helping wounds on the skin recover faster through its ability to rejuvenate skin cells and neutralize free radical damage.

Another line of defense, the cilia (fine hairlike projections from cells in the respiratory system) sweeps away fluids and allergens. The movement of the cilia is a form of energy and negative ions can help stabilize and enhance its movements to actively remove allergens.

A stronger immune system means that a person is less likely to get sick and even if he does get sick, recovery will be faster.

Negative ion atmospheric loading has been reported to affect a range of psychological functions, from alertness to circadian rhythms, and has been suggested to benefit a variety of medical conditions, from allergies to migraines.

In a published paper, "Immunological Effect of Long-term Exposure of Negative Air Ions on Humans", it was shown that the percentage of natural killer (NK) cells with the exposure of the ions was lower than without ions.

4. Balances the Autonomic Nerve System

According to the National Institute of Health, “your autonomic nervous system is the part of your nervous system that controls involuntary actions such as beating of your heart and widening and narrowing of your blood vessels.” Other involuntary actions also include breathing, digestion, perspiration, and dilation of the pupils in the eyes.

The autonomic nervous system comprises the sympathetic nerves and parasympathetic nerves that control the smooth muscle activities of the organ and promote hormone production.

The stress and irregularity of modern lifestyles, such as sleeping late or skipping meals, may cause the autonomic nerves to not function properly by disrupting the rhythms of the sympathetic and parasympathetic nerves.

As a result, more serious health conditions, such as insomnia, frequent night urination, indigestion, depression, hypertension, or heart disease can occur.

With added exposure to negative ions, the balance and normal rhythm in the autonomic nervous system can be restored.
