The video entitled TAKE OFF THE WIRELESS HEADPHONES BECAUSE THEY WILL BOIL YOUR BRAIN is a bombshell! , with a device for measuring the amount of radiation per tectagonal meter with the normal at 10 microwatts, However, a radiation level of 1000 - 2000 microwatts reaches the author's ear, and this radiation continuously emits whether you are talking or not - On the other hand, the Institute of Physics of the UK explains that bluetooth emits a small amount of radiation in the form of extremely high frequency radio waves in the range from 2.402 GHz to 2.48 GHz. Wireless headphones emit significantly less radiation than telephones. This is where the whole non-ionizing radiation thing comes in. - What does it really mean???
Recent videos with tens of thousands of views raised the issue of radiation level safety for your Blue tooth wireless headphones' and gathered many viewers, but also a discussion about whether wireless headphones can cause cancer, memory loss, fatigue and other health problems. Several social platforms have removed these videos, saying they spread medical misinformation. But is there any truth to these claims?
Searching the internet I found that the answer was not entirely clear. “This is a very common concern and question I hear from patients. They want to know if they are at risk because they use wireless devices," said neurologist Mr. Navid Wagl, who thinks the short answer is that it's probably not the only cause.
the UK Institute of Physics explains that bluetooth emits a small amount of radiation in the form of extremely high frequency radio waves in the 2.402 GHz to 2.48 GHz range. Wireless headphones emit significantly less radiation than telephones.
"There's not enough information yet to say for sure or know if this is a contributing factor," Dr. Wagl said.
Despite their widespread acceptance by consumers, this is a relatively new technology and the short time frame means there are many scientists still don't know about the long-term health effects, especially for people who use them for hours every day.
Currently, the US Federal Communications Commission says there is currently no scientific evidence to suggest a causal link between the use of wireless devices and cancer or other diseases. Those assessing the potential risks of using wireless devices agree that more and longer-term studies should investigate whether there is a better basis for safety standards than is currently in use. And the UK Institute of Physics explains that bluetooth emits a small amount of radiation in the form of extremely high frequency radio waves in the 2.402 GHz to 2.48 GHz range. Wireless headphones emit significantly less radiation than telephones. In fact, a 2019 study found that bluetooth headsets emit 10 to 400 times less radiation than smartphones.
What does Greece say about this?
According to the National Telecommunications and Postal Commission (EETT), wired hands-free devices only allow the transmission of audio frequencies that are necessary to communicate.
That is, the hand release components do not relay the radiation to our head.
Bluetooth wireless technology components emit much less radiation than a mobile phone because the distance between the bluetooth headset and the mobile phone is much shorter than the distance between the mobile phone and the base station.
Thus, the burden on the head from their use is significantly less compared to that which exists when the mobile phone is used directly. It is indicated that the transmission power of bluetooth devices is of the order of 1mW at the frequency of 2.45 GHz.
It should be noted that in both of these cases the mobile phone does not cease to function as a transmitter, i.e. it emits radiation as it would if it were in contact with the ear.
For this reason, the position in which the mobile phone is placed during the conversation with hands free or bluetooth is of great importance.
Theoretical calculations as well as measurements have shown that the intensity of the radio frequency energy absorbed when the user moves the device away from his head and body is drastically reduced.
By placing the device at a distance of half a meter from the head, the energy absorbed by the head can be reduced by 100 times.
Health problems due to wireless headphones
In fact, since the use of wireless headphones has become so popular, Ms Collins says the following health problems have increased recently:
Hearing loss
"When you wear headphones, it brings a sound source closer to the eardrum, which can increase the volume louder than intended," says Ms. Collins.
Tinnitus
Using headphones increases the risk of tinnitus or constant ringing in the ears.
Clogging by wax
Ear wax build-up can be a problem, depending on the type of earphones and the shape and size of the earphone.
Contamination
Constant use of headphones also introduces germs into the ear canal where they grow in the warm, moist environment of your inner ear, which can be a catalyst for ear infections.
The pain
If you wear headphones for a long time or if they don't fit your ears, they can cause pain and discomfort and occasional sores in the ear canal.
Both Ms Collins and Dr Wagl say they themselves use wireless headphones from time to time and feel confident about their safety, although they use them sparingly. To stay in the safe zone, it's best to follow the official recommendation that Ms. Collins calls the "60/60 rule": Limit headphone use to 60 minutes at no more than 60 percent of maximum volume. Then take a break from wearing them for at least 60 minutes before returning them.
Wireless headphones, cell phones and cancer – What the scientists say
It is important to keep in mind that wireless headphones are an invention of recent years and thus the data we have regarding their long-term use is limited .
What do the Scientists say?
"Although we cannot know exactly the risk these devices pose, scientists are beginning to realize some potential risks," reports the reputable medical website Healthline .
In 2015, the news website " The Medium " published a report in which various scientists expressed their fears regarding the possible effects of wireless headphones on our health. As the experts pointed out, these concerns do not only concern wireless headphones but also all wireless devices that work with radio frequency waves .
“My concern with wireless headphones is that where they are placed in the ear exposes the tissues in our brain to fairly high levels of RF radiation. Possible risks are brain tumors and various diseases related to abnormal cell functions," said Jerry Phillips, professor of biochemistry at the University of Colorado.
On the other hand, there have been several studies that have shown that the radiation emitted by wireless headphones is significantly less compared to that emitted by mobile phones. In fact, many large organizations such as the American FDA and the American CDC report that there is not enough evidence to support that there is a risk from the long-term use of either.
No more than one hour of use per day
As for the World Health Organization , it now recommends to those who wear wireless headphones that their use does not exceed 1 hour per day , although this specific directive is more related to concerns regarding possible hearing problems , rather than the development of cancer.
It is worth noting here, however, that the International Agency for Research on Cancer has classified the electromagnetic radiation emitted by mobile phones as a "probably carcinogenic substance". A related European Union analysis (which you can read by clicking HERE ) seems to agree, based on almost 10 years of rodent studies.
The various studies that showed the connection between wireless devices that operate on radio frequency radiation, combined with the reporting of "The Medium", prompted 247 scientists from 42 different countries to address a signed letter to the World Health Organization and the United Nations.
In this letter, they asked these international organizations to impose stricter guidelines on devices that emit electromagnetic radiation . We note here that RF radiation is a type of high frequency electromagnetic radiation often emitted by wireless devices such as wireless headsets.
The reason for this request for more restrictions was concerns regarding the health of users exposed to the electromagnetic fields emitted by these devices.
Among others, the following were mentioned as possible effects :
- Cancer
- Genetic alterations
- Neurological diseases
- Problems with learning and memory
- Problems related to the reproductive system
The letter is open and publicly posted online. You can read it by clicking HERE .
Are wired headphones safer than wireless ones?
As the director at the University of California, Berkeley's Center for Family Health reports on the medical website Very Well Health , emissions from wireless devices aren't the only thing we should be concerned about.
Also of great importance is the Specific Absorption Rate (SAR), the amount that the human body absorbs when exposed to a wireless device. This means the proximity of wireless headphones to our head , as they are placed inside our ear, could be a cause for serious concern.
According to the same, it would be good to make proper use and take the necessary protection measures , until we have sufficient data on this issue. In particular, he suggests not using the mobile phone when the signal is not good and to maintain the necessary distances during the day.
"For long conversations, try to use the speakerphone on your phone . The same goes for music, if that's possible. This is even more important for children, who have smaller heads and thinner skulls, making them more sensitive to radiation," says Dr. Santos Kesari, a neuro-oncologist at John Wayne Cancer Institute.
Finally, the " Descriptive audio " website states that wired headphones are considered a better alternative to wireless ones, in terms of radiation
