How to Reduce Bluetooth Radiation

If you’re a frequent user of Bluetooth devices, you may have noticed that the radiation they generate is harmful to your health. Your concern may grow even more when you conduct a brief internet search. According to specific sources, Bluetooth devices might cause cancer, infertility, and neurological problems.

Perhaps you’ve already begun to wonder if Bluetooth is safe to use. They aren’t, to be honest. Although we cannot merely remove the Bluetooth devices from our lives, we can undoubtedly decrease their utilization. To assist you, we’ve put together some information on how to reduce Bluetooth radiation.

We’ll also cover several key points about Bluetooth devices, demonstrating that the statements made on the internet are correct.

What Is Bluetooth?

Bluetooth, which was first introduced in 1989, has gradually progressed to replacing our cords. By 1999, the first consumer Bluetooth gadget was a hands-free mobile headset. Since then, Bluetooth has become a standard in laptops, headphones, keyboards, speakers, cellphones, printers, and other devices. It’s brought in a new era of short-range wireless experiences.

It has a master design and can connect with up to seven devices in a piconet using a packet-based protocol. They can operate without a visual line of sight via a radio communication system.

Bluetooth can function up to 300 feet away, depending on the class. This, however, is contingent on the conditions between the devices, such as wall material, signal fading, and so on. But also Bluetooth works by emitting electromagnetic radiation, which is harmful to our bodies. We’ll go through that in the next section.

How to Reduce Bluetooth Radiation

Bluetooth Radiation: What You Need to Know

Let’s clarify how Bluetooth works before we get started. Bluetooth waves go only a short distance. Most Bluetooth gadgets only have a 30-foot maximum communication range. When walls and other impediments are present, this distance is likewise reduced.

To avoid interference and fading, Bluetooth transmissions typically swap frequencies. Bluetooth is a source of radiation since it emits energy in the same way as phones do. This kind of radiation is known as electromagnetic radiation (EMR).

EMR is a broad word that refers to electromagnetic field waves that transport electromagnetic radiant energy. Examples are radio waves, ultraviolet light, visible light, microwaves, X-rays, and gamma rays. Related: How to Block Radio Waves in Your House 

EMR can be classified as ionizing or non-ionizing depending on the intensity of the emitted radiation. Here’s how to distinguish between the two:

Ionizing EMR

High-energy radiation with shorter wavelengths and higher frequency waves is referred to as ionizing EMR. These are X-rays and gamma rays, which are at the extreme right of the electromagnetic spectrum.

These are distinguished by their tremendous energy and capacity to remove electrons from an atom’s orbit. Ionizing EMR can completely modify the atomic structure of particular objects or substances by changing the charge of an atom. For example, large quantities of ionizing EMR flowing through the body might cause cancer by altering the structure of our cells.

Non-Ionizing EMR

Longer wavelengths and lower frequencies characterize this type of radiation, typically found on the left side of the spectrum. Non-ionizing EMR, in contrast to ionizing EMR, lacks the energy to ionize an atom and modify its charge.

Non-ionizing EMR, on the other hand, can nevertheless heat things; microwave ovens, for example, employ non-ionizing EMR to heat food. Related: Do Microwaves Emit Radiation

What Is Bluetooth Radiation

Disadvantages of Bluetooth


Data transfer is relatively sluggish in all wireless methods. In the case of Bluetooth, this is especially true. The transmission rate of Bluetooth 3.0 and Bluetooth 4.0 is 25Mbps in general. Because Bluetooth is energy efficient, the data transfer process is slower here.

Furthermore, you cannot compare Bluetooth to wired internet direct, with much quicker data transfer speeds. As a result, Bluetooth will be ineffective for sending huge files, such as audio and video. This is most likely used to send tiny images, such as papers. Related: How to Get Wired Internet in Another Room


A Bluetooth connection has a maximum range of 100 meters. Bluetooth has a limited spectrum of communication. The distance of a Bluetooth connection varies based on the version and nature of the devices. This is the range for devices that need to be linked.


Even though most Bluetooth implementations adhere to the standard, there are still challenges with Bluetooth interoperability. This is due to many factors, including profile settings, driver versions, and operating system versions. This is especially true with Bluetooth 4.0’s low-power technology. Other Bluetooth versions won’t work with a Bluetooth 4.0 connection that uses low-energy technology.


Even though Bluetooth has several security features, Bluetooth’s security level is significantly lower because it utilizes radio frequencies. Bluetooth allows hackers to obtain your personal information quickly. Only if you’re within the designated range; as a result, it should not be utilized to send sensitive data. 

How to Reduce Bluetooth Radiation

Minimize Carrying Mobile Phones on Your Body

According to the guidelines, you should keep your phone at least one inch away from your body.

Avoid putting your phone near your body. Put something between your phone and your body, such as your wallet, if it’s in your hip pocket, to reduce radiation reaching your reproductive system, kidneys, and other organs.

You should keep phones away from soft body regions, which are readily harmed. It may induce breast cancer and hurt your heart if it is found in your shirt pocket. If you’re driving, make it a habit to leave your phone on the dashboard or a holder when you get in the car.

Auxiliary Cable

Let’s start with the issue that many individuals want to play music from their cellphone over their car entertainment system. You have two convenient choices to do it. First and foremost, most contemporary car entertainment systems now include an auxiliary In port. All you’ll need is an auxiliary cable to connect your mobile to your car sound to complete this. 

Put one end into your cellphone and the other into your car radio system, and whatever you listen to on your phone will now be played through your car stereo system. This eliminates the need to use Bluetooth to play music.

USB Phone Charge Cord

Your second option is slightly superior. Most modern cars now have a USB Phone Charge Cord connector, which allows you to put in your cell phone and listen to music over your car sound, similar to how the Auxiliary Cable works. 

The difference is that instead of using your cellphone, you can utilize the USB connector to manage the music, tracks, and volume from your car stereo settings. This provides a more hands-free option for driving, which is safer. 

Cut The Cordless

Because both the handset and the base station of a cordless phone generate radiation, they have twice the cellphone’s radiation. What makes them significantly more dangerous is that they continue to do so even when not in use.

Equip your landline with an extension cord and unplug your cordless phone.

Go Wired

When compared to wireless connections, wired connections generate very little radiation. Wi-Fi radiation is lower than that from telephones, but the constant exposure adds up.

If you use a desktop as your primary device, utilize an ethernet cable to connect it. Unless you need to use a device, turn off the Wi-Fi. When you’re done, use the device, turn it off and leave it off until you need it again. Also, when you go to bed, turn off the Wi-Fi.

Keeping Track of GPS

Car GPS navigation systems are quite helpful. However, in certain circumstances, they have been proven to emit such high levels of radiation that the firms that manufacture them have been blocklisted.

Please turn on your car’s GPS navigation when you need it.

Your cellphone’s GPS radio sends data to update your location regularly. The good thing is that you may use this to locate a misplaced phone. The disadvantage is that it adds another radio to the phone, which emits additional radiation.

Radiation Free Hours

Children’s bodies are less immune to radiation, putting them at greater risk. Children should not use the cellular network at all if at all possible. If at all feasible, encourage your children to utilize the landline. If they have to use a cellphone, the call should be brief and, if feasible, on speakerphone.

Shorten the time your children are exposed to radiation by establishing radiation-free hours. Please switch off the Wi-Fi before going tonight, and don’t turn it back on until the kids have departed for school or midday. It’s also beneficial to your health. 

Go for Messaging

Texting is safer since it keeps your phone away from your face. When you’re driving, there’s an exception to the norm.

You can now send voice messages through messaging apps if you don’t enjoy typing.

Alternatively, try dictating. Cellphones can now pick up on what you’re saying and even be programmed to match your accent. Tap the microphone icon on your phone’s keyboard, narrate your message, check it for typos, correct it, and send it. The adjustment period will be lengthy, but it will be well worth it in the long run.

Finally, typing while carrying your phone exposes your hands to radiation. Learn to type while holding the phone on a table, a pillow, or something else.

Types of Bluetooth

Although some reputable organizations may claim that Bluetooth waves are carcinogenic, you must consider the different classes of Bluetooth to determine whether or not these waves have the power to modify DNA. Bluetooth is divided into three categories:

Class 1

This category includes the most potent Bluetooth devices. These devices can operate at a maximum output of 100 mW and have a range of over 300 feet (100 meters). These are the most harmful to the human body.

Class 2

One of the most prevalent Bluetooth classes, which you can find on a wide range of devices. It reaches around 33 feet (10 meters) and can transmit data at 2.5 mW.

Class 3

This category contains the least powerful Bluetooth technology devices. These gadgets range around 3 feet (1 meter) and use 1 mW of power.

Some Bluetooth gadgets emit 0.23 Watts per kilogram of radiation, but some are worse and emit more significant radiation than some SAR cell phones. Knowing how much radiation you’re exposed to every time you turn on your Bluetooth device will help you take the necessary precautions to reduce your risk of exposure.

Using Air tube headsets and Ferrite beads rather than Bluetooth headsets is one of the most remarkable ways to reduce Bluetooth radiation exposure. Instead of utilizing Bluetooth, you can connect your phone to the car stereo. The ferrite beads shield the brain from RF radiation. To protect yourself from Bluetooth radiation, make sure all headsets have ferrite beads. 

Bluetooth and SAR

It would be best to consider the SAR value aside from the three Bluetooth classes and their various operating frequencies and power levels. When exposed to an EMF, the SAR (Specific Absorption Rate) is the rate at which radiation is absorbed by the human body (RF). The value aids in estimating how much power a body (including the head) absorbs per mass of tissue.

In general, an ordinary pair of Bluetooth headphones has a SAR value of roughly 0.30 watts per kilogram. It is significantly below the FCC’s recommendation that a device’s SAR value not exceed 1.6 watts per kilogram. To give you an example, Apple AirPods, one of the most popular truly wireless headphones, has a SAR value of 0.466 watts per kilogram, which is below the FCC’s restriction.

Some argue that because microwaves and Bluetooth both employ radio frequencies in the same range, Bluetooth radiation is just as dangerous as microwave radiation.

Is Bluetooth Safe for the Brain?

Bluetooth headphones emit electromagnetic fields that can harm your brain cells and raise your risk of developing brain cancer. As a result, any device that uses Bluetooth technology to send data or communicate with another Bluetooth device, even if it emits minimal levels of radiation, might cause health problems.

All of this may make you appear paranoid. However, we believe that if you’ve read thus far, you’re already aware of and concerned about the radiation emitted by your Bluetooth devices.

We must admit that we adore our electronic devices and are surrounded by far more than we can count. We don’t want to abandon them. As a result, we’ve attempted to demonstrate how to reduce Bluetooth radiation.

Hopefully, this article has addressed any reservations you may have had about using Bluetooth in your everyday life. We also hope that we’ve explained why Bluetooth gadgets are dangerous and unreliable.
