What Are Negative Ions And What Are Their Benefits?

Negative ions can help contribute to good health as extensive research is showing the dissipation of them in our natural environment. They are in the air we breathe, the food we eat and the water we drink. They are able to neutralize free radicals and prevent oxidation, this helps improve all the body’s natural biological functions such as improving cell metabolism, enhancing immune function, purifying the good, balancing the nervous system, improve digestion and more.

There are many ways to get the negative ions we need including being in nature, eating healthy alkaline foods, drinking alkaline anti-oxidant water and wearing negative ion products. All these methods get us the negative ions we need but with pollution, poor quality food/water and other negative environmental impacts there are no longer a sufficient amount of negative ions.

What are negative ions?

You probably have heard the word “negative ion” a lot but may still not know exactly what they are or the benefits they have. Negative ions are an atom or molecule with an additional electric giving that atom or molecule a negative charge. In contrast a positive ion is an atom or molecule that is missing and electron giving it a positive charge.

Why do I need negative ions?

You may be asking yourself why negative ions are beneficial, why do you care about an extra electron? Why negative ions benefit us is because they can use their extra electron to neutralize positive ions which are also known as “free radicals”. Since positive ions or (free radicals) are missing an electron they desperate want to find an additional electron to stabilize themselves. The positive ion or (free radical) will pull an electron off a neighboring molecule from you, causing the affected molecule to become a free radical itself. A chain reaction can then occur as the new free radical will pull a free electron off another neighboring molecule. Eventually as this chain reaction occurs an electron can be pulled from a molecule that cannot function without that electron. Now you are stuck with a cell that can no longer function properly.

This chain reaction and continue to occur causing atomic structures in the human body to start cross linking. Cross linking is when two similar atomic structures must share an electron to stabilize due to the missing electron. Cross linking can occurring in DNA which can lead to various effects such as aging and cancer. Additionally other cross linking can occur between the protein and fats in our body leading to wrinkles.  For example LDL (Low density Lipoprotein) will start the formation of plaque in arteries when oxidation occurs. This can lead to heart disease and stroke.

This of course only scratches the surface of the diseases that can be caused due to oxidation to the body caused by free radicals (positive ions). Free radicals are most damaging to biological structures like us as this unnecessary oxidative damage has shown to shorten lifespans and lead to other degenerative diseases.


When we introduce negative ions we are able to neutralize there positive ions (free radicals) as their electron transfers over to the positive ion and both molecules become neutral.  This same principle applies in our bodies and cells, molecules in our body that are missing electrons and acting as free radicals now have excess electrons to use bringing them back to their natural state. Additionally it is possible that cross linking that has occurred can be undone if there is a surplus of negative ions for those atomic structures. Negative ions help in two was; neutralizing positive ions (free radicals) before they can cause harm and additionally repairing any oxidative damage done to the body caused by free radicals.

By providing the body with ample negative ions we are able to slow down and even reverse the aging process while helping prevent diseases from occurring.

Where do I get negative ions?

The good news is there are ample negative ions available, but the bad news is there are an ever increasing amount of positive ions counteracting them in our industrialized environment. Historically there were 1.2 negative ions to every single positive ion in our environment. However this ratio has reversed and we are more likely to find 1.2 positive ions for every negative ion. The result is our bodies are constantly undergoing free radical damage to all the excess positive ions. That is unless we provide it a surplus of negative ions.

Negative and Positive Ion Levels Measured in Various Locations

  Negative Ions Positive Ions
Offices 70 1,400
Industrial Areas 50 300
Shopping Arcades 220 280
Residential Areas 200 180
Forests 2,500 800
Kowakidani Hot Spring 2,500 820
Near Minoh Waterfall 5,000 300

(These measurements were taken in Japan)


Forests and Plants

As you can see natural areas that have not been developed and industrialized have a vastly larger amount of negative ions. Plants are one of the main producers of negative ions which are why we find so many in forests and areas with lots of plant life. There is no coincidence that studies have shown houseplants improve air quality. The negative ions they produce do more than help of bodies fight free radicals, the negative ions produced by plants will actually purify the air by neutralizing dust, mold spores, bacteria and allergens.

Waterfalls, hot spring & other anti-oxidant rich waters

 In nature hot springs and waterfalls also have a surplus of negative ions which occurs in the journey the water takes. When water travels in nature it passes over rocks and clays picking up essentially minerals which also happen to have a surplus of negative ions. We can measure these negative ions by using an ORP ( oxidation reduction potential ) meter which can tell us if we have a surplus of negative ions of positive ions. We can benefit from these negative ions by being around waterfalls (absorbing them as they come loose ), bathing in the water the hot springs, or even drinking water with additional negative ions. You can achieve this by drinking alkaline anti-oxidant water like Cerra Water.

Vitamins & Minerals

The food we eat is also another important source of negative ions as anti-oxidants (negative ions) are found in vitamin A, vitamin C, vitamin E , beta carotene and superoxide dismutase. Unfortunately the majority of foods eaten today are low in these vitamins and minerals. This is largely due to mineral depletion in our soil. Over the last 100 years minerals in the soil has decreased 90%. Without the proper nutrients in the soil we are unable to get the proper nutrients from the food we eat.

The problem

You probably do not live in a forest and are either in a house or office at your computer so right away there are not sufficient negative ions in your environment. You are also not getting the negative ions from your tap water as all city water is loaded with free radicals. Additionally the food we eat is also poor in the vitamins we use to get our anti-oxidants from due to poor top soil. Even if you are able to get the negative ions you need those will quickly be cancelled out due to high positive ion sources. The fact is unless you are living off the land in the forest your environment is full of positive ions (free radicals) and low in negative ions.

The solution is negative ion products

We can supplement our bodies with the negative ions needed by using Iyashi negative ion products. Through the minerals used and piezo electric currents Iyashi products produce over 5000 negative ions per minute. Many minerals carry extra electrons while others can generate them such as tourmaline and germanium. By concentrating these natural negative ions sources we can easily provide our bodies with the negative ions needed to counteract free radicals and oxidative damage.

The amount of negative ions received by wearing an Iyashi bracelet or pendant is similar to standing out in a forest 24/7. While you still should try and got out in nature due to the many other health benefits neutralizing positive ions and repairing oxidative damage is vitally important for your health and wellbeing. In modern society it will always be a constant struggle to receive the negative ions needed. If you provide yourself with a constant stream of negative ions you can always be fighting free radical damage which can benefit your health and the body’s natural healing process.

Benefits of Negative ions
