Are Bluetooth Headphones Safe For Your Brain? (Explained)

Because Bluetooth is a member of the non-ionizing category of EMR, which emits low-frequency waves, it is safe for individuals and won’t harm their mental health. These frequencies are insufficiently low to alter the cellular structure.

We constantly search for better and healthier ways to conduct our lives. Sometimes our desire to live better than we already do may be so great that we search for the greatest diets, vitamins, and even nootropics to develop a strong immune system. 

Another component of leading a healthy lifestyle is being conscious of what we submit our bodies to. Bluetooth technology is one thing that many of us are frequently exposed to. 

How safe is Bluetooth? We all have at least one Bluetooth device in our houses. Our phones, Bluetooth headphones, portable speakers, and televisions all may be involved. No one can shield themselves from these radiations as a result.

Let’s see if Bluetooth technology possesses any risks.

What is Bluetooth Technology?

Bluetooth is a wireless connection protocol that technology developers use to link up various gadgets wirelessly. 

While attempting to link devices together within a specific range, Bluetooth uses short-range radio frequency. The usage of radiofrequency radiation is also a feature of wireless Bluetooth devices. EMR, which travels in waves utilizing electric and magnetic fields, includes that kind of radiation. 

The natural and artificial worlds both contain them. Radiofrequency radiation is produced by radios, televisions, and cell phones. 

It’s crucial to remember that Bluetooth devices emit around one-tenth or less of the radiation that cell phones do, according to Ken Foster, Ph.D., a retired professor of bioengineering at the University of Pennsylvania in Philadelphia.

Hence, if you listen to music or podcasts on wireless Bluetooth headphones for several hours each day, that exposure might mount up. Nevertheless, you’ll get less exposure if you use them for phone calls as opposed to holding your phone up to your ear.

Is Bluetooth Radiation Harmful?

The range of Bluetooth waves is somewhat limited. In actuality, the majority of Bluetooth devices typically only have a 30-foot maximum communication range. When there are walls and other obstructions, this distance is also shortened. 

Bluetooth waves frequently change frequency to avoid fading and interference. Nevertheless, it operates between 2.402 and 2.480 gigahertz in frequency. This happens at the same wavelength as the microwave, Wi-Fi, and cell phone frequencies. 

Similar to how phones emit energy, Bluetooth also emits energy, making it a source of radiation. This form of radiation is known as electromagnetic radiation (EMR). EMR is an umbrella term for electromagnetic field waves that transport electromagnetic radiant energy. 

They include X-rays, gamma rays, visible light, infrared, radio waves, and microwaves. Depending on the intensity of the radiation being emitted, EMR can be categorized as either ionizing or non-ionizing.

How to distinguish between the two is as follows:

CategoriesDetails
Ionizing EMRHigh-energy radiation with shorter wavelengths and higher frequency waves is referred to as “ionizing EMR.” They belong to the electromagnetic spectrum’s far right, where X and gamma rays are located. They are distinguished by their great energy and capacity to knock electrons out of an atom’s orbit. Ionizing EMR can completely alter the atomic structure of some objects or substances by altering an atom’s charge. For instance, ionizing EMR at high levels can change the structure of our cells to the point that it finally results in cancer.
Non-Ionizing EMRThey are lower frequency, longer wavelength radiation that often resides on the left side of the spectrum. Non-ionizing EMRs lack the energy necessary to ionize an atom and alter its charge, in contrast to ionizing EMRs. Non-ionizing EMR can nevertheless heat materials, as shown in microwave ovens, which use non-ionizing EMR to heat food. Ionizing EMR, especially in large doses, has the potential to severely change the chemical connections that make up human tissue. Burns and organ damage are only two examples of the instant harm they may do. Non-ionizing EMR, on the other hand, can simply flow through the body without harming it.

Do Bluetooth Headphones Cause Cancer?

Although Bluetooth headphones were first released on the market in 2016, it may be difficult to recall a time when everyone started wearing them. 

There is now no proof that Bluetooth gadgets raise the risk of getting cancer, despite the wildfire spread of the allegations that they cause it. 

The quantity of radiation emitted by Bluetooth devices is 10 to 400 times lower than the amount emitted by cell phones, according to a 2019 study by the California Department of Health.

Another study examined the use of mobile phones among 5,000 persons who had brain tumors and came to the conclusion that adult brain tumors are not caused by mobile phone use. 

Similar findings were reached in the UK by a sizable study including 800,000 randomly selected females, which revealed no link between cell phone use and an increased risk of brain cancer. 

There is no proof that radiofrequency radiation can cause cancer, according to the National Cancer Institute. The scientific community is still not entirely clear despite this data.

Does Bluetooth Headphone Cause Brain Damage?

It’s possible that using Bluetooth gadgets that generate radio waves won’t immediately harm your brain. 

Any issue, though, might be related to prolonged exposure. Does Bluetooth pose a long-term risk to the brain? This also probably has a negative answer. The amount of energy that Bluetooth gadgets utilize to get to the brain is relatively modest. 

These Bluetooth radio waves cannot generate enough heat in the brain to result in any long-lasting neurological diseases. And this is still true even after using them for numerous hours, weeks, or months: the chance of developing cancer is not noticeably higher.

Safety Precautions to Take When Using Bluetooth Headphones

Although the popular misconception that the radio frequency from Bluetooth devices is safe has already been disproven, it is still preferable to be safe than sorry. 

Here are a few proactive steps you can take to reduce the likelihood of adverse consequences as much as you can.

StepsDetails
Avoid Exposure To Multiple EMR DevicesThe SAR levels from your phone and Bluetooth headphones may not be sufficient to change the structure of human cells, it is true. Imagine, however, that you are carrying your phone and a pair of Bluetooth earbuds while working in a hospital’s radiation department. Your actions expose your body to varying doses of EMR radiation, which cumulatively raises your total SAR levels. It is possible that this will raise the chance of developing cancer and other radiation-induced neurological problems. You are still putting yourself in danger even when you may be eating a nutritious diet or chewing gum to keep alert.
Opt For Hands-Free Options When Answering CallsUsing the hands-free option to answer your phone when possible is yet another approach to lowering your chance of developing cancer from radiation overexposure. Use your speakerphone instead. Another sound option is to use wired headphones, which do not require your phone’s Bluetooth to be powered on.
Limit Your Child’s Proximity To EMR-Radiating DevicesIn general, children are more vulnerable to radiation. Limit the amount of radiation they are exposed to in that event. You can prevent them from using phones, WiFi routers, Bluetooth gadgets, or microwaves by keeping them out of their reach. By avoiding harsh direct sunlight or just covering them with sunscreen when they are outside, even exposure to UV light from the sun can be reduced.

Conclusion

  • The usage of Bluetooth headsets, speakers, and headphones does not intrinsically harm cells and is unlikely to result in brain cancer. They have their own set of benefits, such as enabling you to focus without being constrained by cables. 
  • The ability to work and move freely without being constrained by wires, as well as dance without tagging on a wire, is an extra benefit. 
  • There is still a tonne of research being done because science is continually changing as a result of new findings. This necessitates that you use caution when using any technological gadgets.
  • Take the safety precautions outlined above to prevent radiation exposure from resulting in any health issues.
