Effects on the human body
Q.01 - The more negative ions, the better for health?
We do not have enough information to conclude the more the better. Various negative ion effects on the human body have been reported. Some medical literature written over half a century ago shows that high density negative ions are not always good for health.
However, there has been no report that high density negative ions have a negative effect while many negative ion generators have been in the market for many years, so there is no immediate health concern.
Q.03 - How are negative ions absorbed by the human body?
It is said that negative ions are absorbed by breathing and skin.
Q.04 - How do negative ions work on the human body?
It has not been fully elucidated yet. It has been said that negatively charged electricity which negative ions posses or the chemical properties work on the human body.
Q.11 - I heard "radiation rays = negative ions". Does this mean negative ions are harmful for the human body?
Negative ions are not harmful because they are different from radiation rays. Radiation rays cause ionization to form negative ions in the air, which may cause confusion.
* Negative ions are also generated by splashing water or lightning as static electricity is discharged.
Q.12 - Do positive ions always produce negative effects on health?
While many research reports show that positive ions have negative effects on the human body, some indicate positive/no effects. There are far more research reports on (positive effects of) negative ions.
Q.13 - Does negative ion therapy work for bronchial asthma?
We cannot say that bronchial asthma is cured by negative ion therapy but the symptoms can be quickly alleviated. This is because negative ions are said to help to expand bronchial tubes. Some hospitals use negative ions for the therapy of bronchial asthma.
Q.16 - What is the best way for the body to absorb negative ions?
Using a negative ion generator is the best way to absorb negative ions because it generates negative ions whose density is higher than any other negative ion product. Negative ions' positive effects on the human body have been reported in medical literature since around 1900. Most of the effects were obtained by using negative ion generators. You can also refer to Effective way to take negative ions.
Q.18 - Why does exposure to negative ions reduce irritability, tenseness, with increased calmness and stimulation?
This is often explained that negative ions work on the autonomic nervous system but this theory is not widely accepted. Negative ions control the sympathetic nervous system to stimulate the parasympathetic nervous system.
Q.19 - Will negative ions help with depression?
We have received reports that our negative ion generators help to alleviate depression but it is not medically proven.
Q.20 - Are there any reports on the clinical use of negative ions?
Negative ions have been used for various treatments for many years. The effects have been reported in medical literature. Please refer to "Negative ion effects reported in medical literature".
Q.21 - Do negative ions have any effects on the human body when exercising ?
This clinical test was not carried out while patients were exercising but it shows negative ions have effects on pulse rates.
Q.22 - Will negative ions help with Sick house syndrome?
It is not scientifically proven but negative ion products which remove formaldehyde and other volatile organic compounds (VOCs) can help to alleviate the symptoms.
Q.23 - Do negative ions really work as well as antidepressants?
We have received some reports that negative ion therapy produces positive effects but negative ions are not medication. You should consult a doctor, if you need treatment.
Q.24 - Are negative ion generators safe to use during pregnancy?
No negative effects on expecting mothers have been reported. However, you could turn off your negative ion generator until the baby is born in order to maintain psychological stability if you are nervous.
Q.25 - Are negative ions beneficial to infants?
No study suggests that negative ions are less effective for infants.
Q.26 - What are the long term effects (genetic or otherwise) of prolonged exposure to negative ions?
No negative effect caused by long term use has been reported.
For your reference: Immunological Effect of Long-term Exposure of Negative Air Ions on Human (Ichiro WATANABE, Yukio MANO) (J Jpn Soc Balneol Climatol Phys Med Vol.64-3 May 2001 Issue)
Q.27 - What is a hormesis effect?
A substance, that is normally harmful to creatures, can produce positive effects when taken in a small dose.This phenomenon is a hormesis effect. Well-known examples are clothing and bedding products which include ores and hot spring water that contain radon as they emit a very small dose of radiation.
Radiation is harmful to the human body when it exceeds a certain level. However, a very small dose of radiation can produce positive effects. Scientifically, it has not been proven how radiation works positively.
Q.28 - Do a hormesis effect and negative ions relate each other?
Some products such as clothing and bedding use radiation to produce a hormesis effect.
The air is ionized when the radiation is released. So, a hormesis effect and negative ions relate each other.
Q.31 - Do negative ions work for hay fever?
It has not been proven scientifically but many customers find that our negative ion products work for hay fever.
