Do Wireless Bluetooth Headphones Cause Cancer?

Do Wireless Bluetooth Headphones Cause Cancer

Wireless Bluetooth headphones have become an in-thing amongst the millennials. But, have you ever asked yourself whether wireless Bluetooth headphones cause cancer?

Recent research on the link between cancer and cell phone radiation carried out on rodents raised various concern amongst scientists. However, some analysts questioned the relevancy of the findings conducted in 2000 concerning newer wireless technologies like Wifi and Bluetooth that have recently emerged.

Most electronic devices use an electromagnetic radiation form known as RF (radio frequency) energy. For instance, routers and cellphones use RF to relay wireless internet to other devices like TVs, and computer. Likewise, Bluetooth headphones also utilize RF signals to play music.

Do You Need To Worry About The Radiation From Wireless Bluetooth Headphones?

Well! To find out, we got various opinions from the experts on what they thought the radiation that comes out of these devices and steps you can take to reduce such a risk.

What do most people are unaware of about the radiation that these devices emit?

Bluetooth, Wifi, and cell phones usually produce nonionizing radiation as the RF signals are transmitted. This is quite different from the ionizing radiation from X-rays, CT scans, nuclear explosions or the sun’s ultraviolet light. That is why some scientists argue that the energy found in the non-ionizing form is not adequate to alter the DNA that will eventually predispose an individual to get cancer like the other radiation form.

With that in mind, there is still some research that seems to suggest that nonionizing forms substantially affect living organisms. But, the debate that is still ongoing is how worrisome are those effects.

Even though lab studies on RF signals safety risks are not conclusive, some scholars like professor LeekaKheifets, Ph.D., of UCLA School of Public Health seems to suggest that Bluetooth devices have less potential effects on health.

He even suggests that Bluetooth headphones that are used close to the body have weak signals, posing less risk that the RF signals that cell phones transmit.

Bluetooth Headphones Cause Throat Cancer?

Some medical scientist has tried to find out whether wearing Bluetooth headphones can trigger throat cancer. But, what is throat cancer?

As compared to other kinds of cancer, throat cancer is one of the most uncommon kinds of cancer according to the US National Cancer Institute. Throat cancer usually affects various parts of the throat like the vocal cords, the voice box, oropharynx, and tonsils. The main categories of throat cancer many people are familiar with are:

  • Pharyngeal cancer: which develops around the throat and neck which is also known as the pharynx area.
  • Laryngeal cancer: it affects the voice box where the larynx is located.

Although there is no informative report about the linkage of headphones and throat cancer, the issue is still a worry to some individuals. As of now, it is hard to conclusively establish that the Bluetooth headset radiation can cause throat cancer. More data is needed.

Bluetooth Headphones Cause Brain Tumors?

This is a very crucial question to ask if you are fond of using Bluetooth headphones.

Thanks to modern technology, you can easily talk while doing other things like skiing and driving to the person you want through the use of Bluetooth headsets.

Bluetooth headsets are wireless extensions that make you make conversations without holding the cellphones. The radiation that comes from the cell phone according to WHO has carcinogenic effects. While doctors usually advise people not to hold their phones onto their ear for a prolonged time, some people think that a Bluetooth earpiece is the best option. But, it is wrong!

While the radiation intensities in Bluetooth are generally lower than cellular signals, wireless headphones are usually placed near the head directly on the ear. The head has conductive tissues which act as an ideal antenna; therefore, the external electromagnetic fields usually interrupts electrochemical signals that cells use to communicate. Such a scenario is usually evident in the head together with the brain tissues come into contact with EMF radiation for a long time.

A leading researcher in the biological effects of radiation, Dr. Andrew Goldsworthy, cell phones and Bluetooth pulses cause irreparable DNA damage as it interferes with calcium ion signaling. The U.S. National Toxicology also suggests that High radiation levels increase the risk of getting gliomas (malignant brain tumors) and schwannoma (benign nervous system tumor).

Bluetooth Headphones Also Cause Other Health Issues?

Apart from cancer, Bluetooth devices—in this case, Bluetooth headphones— can cause other health hazards. Many people prefer communicating using Bluetooth headphones over cellphones, but such devices are not entirely that safe. Various potential health hazards emanate from long exposure to microwave signals as follows:

Ear pain: Bluetooth headsets after prolonged use can cause ear pain. When some companies manufacturing these Bluetooth headsets try to make them cool, they end up making them heavier instead. When Bluetooth headsets are clipped on the outer section of the year, its weight tends to harm the ear’s muscles causing a lot of pain. To avoid such discomfort, Bluetooth headphones require proper cushioning.

Deafness: as we use Bluetooth headphones, most of us forget that our ears can only handle for a long sound that is less than 85 decibels. To prevent loss of hearing ability, avoid exposure to high volumes over an extended period.

Leukemia: another hazardous thing about Bluetooth technology is the risk of leukemia. Although Bluetooth devices do not produce strong radiation as microwave radiations, it still predisposes an individual to other conditions like immunity distortion, leukemia, and other diseases.

Hair loss: this is another worrisome side effect that Bluetooth headphones are assumed to cause. Usually, early baldness occurs after prolonged use of Bluetooth devices.

What To Consider When Using Wireless Bluetooth Headphones?

It is a fact that these headphones have radiations that can be harmful when you are exposed to them. So, if you minimize the level of exposure, then the potential harm will be reduced. According to experts, there are certain steps you can take to limit such exposure.

Here is what you can do to limit the RF signals that emanate from the phone:

Consider not to be using your headphones all the time every day. Just try to limit the amounts of times that come into contact with these devices on a daily basis. When you are going to bed, ensure you switch off those devices.

Is Wearing Truly Wireless Earbuds Safe Or Not?

Bluetooth earbuds have become convenient and cool things. But, what do various studies conducted tell us about these tiny transmitters that are usually inserted on the ear?

Some of these researches are terrifying. For that reason, should we leave the Bluetooth devices and phones so that we go back to the writing letters error to communicate? While such an idea can be relieving, it is not realistic in the current century. In fact, some of these devices like wireless earbud are handsfree and reduce the exposure of a lot of radiation to your head.

According to bioengineering professor at the University of Pennsylvania, Dr. Kenneth Foster, almost all the earbuds are tested to ensure that they comply with the FCC radiation exposure limits before they enter the US market.

Instead of directly placing your smartphone over the ear to make phone calls, it is safer to use wireless earbuds or Bluetooth headphones as it keeps your phone at least 25 mm away from the body.

FAQ For Bluetooth Headphones

How long is it safe to use a Bluetooth headset every day?

Cases where people experience headaches and migraines after prolonged daily use of Bluetooth headphones to hear movie sounds or music have become common. To maintain safety, WHO advises people to use those wireless headphones up to one hour a day while maintaining the volume below 60% — which might not be appealing to the young people who like listening to noisy music for long using their headsets.

How about the radiation of Bluetooth earphones?

When using Bluetooth earphones, you should be careful of the amount of radiation you will expose your body. Like headphones, Bluetooth earphones are generally safe to use but WHO advises people not to use them for longer than 90 minutes.

Is it true that Bluetooth 5.0 radiation causes more harmful effects on the human brain?

Not really! There is no study conducted on Bluetooth 5.0 to determine the effects of its radiation on the human brain. Rumors suggest that it can be more dangerous, but this is just a fallacy as no one has come out to claim injury after using Bluetooth 5.0. It is a new technology that needs many studies to compare it with other older versions like 2.0, 3.0 and 4.0.

Can I get cancer from wearing wireless headphones each night?

No! I don't mean that only when you wear wireless headphones at night is when you will get cancer. If you use them at night only, the health risks are pretty lower.

Are round-neck Bluetooth headphones harmful for the health?

Round-neck Bluetooth or behind-the-neck headphones have a flexible band — even though they are moderately thick — between two earpieces. These kinds of headphones are pretty expensive.

These kinds of Bluetooth headphones emit high radiation that the other simple wireless headphones. Therefore, they can be harmful when excessively used.

How to use Bluetooth headset correctly in daily life

Even though Bluetooth headsets usually transmit low-intensity radiation, they should be cautiously used. Therefore, do the following:

  • Know the kind instructions prescribed for the Bluetooth you are using.
  • When placing your Bluetooth headphones or Bluetooth earbuds on your ear, ensure it is necessary.
  • Avoid using your Bluetooth headphones throughout the day even when it is not necessary.
  • Turn off your Bluetooth headphones and devices when not in use.


Earlier on the FDA used to approve the Bluetooth technology without pretesting. However, concerns have emerged that these wireless Bluetooth headphones cause cancer and other health issues.

In a relieving way, most scientists agree that Bluetooth is generally safe. But, the only thing you should be cautious about is excessive use of Bluetooth headphones or wireless headsets.
