Negative ion and far infrared stress-relief eye mask?
Hello Dr.
Yang! There are eye masks on the market that claim to use negative ions and far infrared components for stress relief and other benefits.
I would like to ask you about the safety standards for such products for human use.
Are there any standards in our country that we can refer to? For example, for normal individuals wearing these products daily, what should the daily dose not exceed, and what would be the calculation method (e.g., per hour) in terms of mSv/hr? Thank you!

Dear Mr.
Chen,
Hello.
Regarding the information related to negative ions, it has been collected by the National Science Council and the Forestry Bureau of the Council of Agriculture.
Please refer to the attached document for details.
From the information in the attachment, it can be seen that the indicator for such products is the amount of negative ions.
A certain eye mask claims to have a negative ion concentration of 3000 ions/cc, but does not mention the method of generation.
If it does not utilize ionizing radiation technology, there should be no risk of radiation exposure that you are concerned about.
Wishing you peace and health.
Sincerely,
Dr.

When it comes to the safety standards for eye masks that claim to use negative ions and far infrared components for relaxation and other benefits, it is essential to understand both the scientific basis behind these claims and the regulatory standards that govern their use.
Firstly, negative ions are believed to have various health benefits, including improving mood and reducing stress. However, the scientific evidence supporting these claims is still limited. Far infrared (FIR) technology is often marketed for its purported ability to improve circulation and relieve pain. FIR works by emitting infrared radiation that can penetrate the skin, potentially leading to a warming effect that may promote relaxation. However, the effectiveness of these products can vary widely, and not all claims are backed by rigorous scientific research.
In terms of safety standards, different countries have their own regulations regarding consumer products, including those that emit radiation or heat. In the United States, the Food and Drug Administration (FDA) oversees the safety of medical devices, while the Consumer Product Safety Commission (CPSC) regulates general consumer products. For eye masks that claim therapeutic benefits, they may need to comply with specific regulations depending on their intended use.
In Taiwan, where you are inquiring about safety standards, the Ministry of Health and Welfare is responsible for regulating medical devices and ensuring that they meet safety and efficacy standards. If a product is marketed as a medical device, it must undergo rigorous testing and approval processes. However, if it is marketed as a cosmetic or general wellness product, the regulations may be less stringent.
Regarding the daily dose of exposure to negative ions or infrared radiation, there is currently no established standard for how much is considered safe for daily use. The concept of a "daily dose" in terms of mSv/hr (millisieverts per hour) is typically applied to ionizing radiation, such as X-rays or gamma rays, rather than non-ionizing radiation like infrared. Non-ionizing radiation is generally considered safe at typical exposure levels, but prolonged exposure to high levels of heat can cause thermal injuries.
For consumers, it is advisable to follow the manufacturer's guidelines regarding the duration and frequency of use. If a product suggests a specific duration, such as 20-30 minutes per session, it is wise to adhere to those recommendations. Additionally, if you experience any discomfort or adverse effects while using such products, it is best to discontinue use and consult a healthcare professional.
In summary, while negative ion and far infrared eye masks may offer some benefits, it is crucial to approach their use with caution. Ensure that any product you consider has been tested for safety and efficacy, and always follow the manufacturer's instructions. If you have specific health concerns or conditions, consulting with a healthcare provider before using such products is advisable.
