Are Bluetooth headsets harmful to your health?

Do you have a Bluetooth headset for your cellphone, computer or any other device for that matter? Well, the answer to that question could be yes or no. Either way, many people have a mobile phone accessory because it allows them to take calls, listen to music, and do other things effortlessly. Indeed, it is commonly used among trendy people, making it a very trendy hands-free device. However, there are growing concerns that it could be harmful to health. As a user, do you have any reason to be worried? Well, you will get the answer after going through this guide.


About Bluetooth Technology

Bluetooth products are extensively used in cellphone headsets, computer accessories, and various medical health and wellness devices. Bluetooth has made our work easy. While driving, it helps you to focus and not get distracted when talking to someone on the phone. Wireless devices have made our life easier. Although Bluetooth is helpful, it has its own side effects owing to radiation it emits. Bluetooth is a wireless technology that uses radiofrequency signals. Bluetooth transmits radiations at frequency levels of 2.4 GHz band. Radiation exposure depends on the transmission power. The higher the transmission power, the greater the radiation, and the more the damage.


Classes of Bluetooth Product

Three kinds of Bluetooth products are available.

Class 1 has a maximum transmission power of 100mW (20dBM) and can operate to as far as 100 meters. They are extremely powerful, and usually emit the highest level of Bluetooth radiation.

Class 2 has a maximum power of 2.5mW (4dBm) and can operate within 10-meter range.

Class 3 which has a maximum power of only 1mW (0dBm) and has an operating range of 1 meter. The weakest of three.

Using a Bluetooth headset is equally as dangerous as using a cellphone, considering the radiant waves emitted. However, they emit a much lower level of radio frequency (200 times less than cellphones), which pose no significant health risk for the user.



Are Bluetooth Headsets Harmful?

Bluetooth headsets emit microwave radiation. Microwave signals have shorter wavelengths and a rapid rate of oscillation, which enables them to carry information over long distances without wires. Their short wavelengths and rapid oscillation also help them to penetrate living tissues down to the cellular level. It, in turn, cause a biological change, which could also be transmitted to the offspring. Bluetooth’s adverse effects may include ear pain, hearing loss (especially, with loud noises), neck pain, headache, hair loss, etc. It is also said to cause brain cancer, leukemia, miscarriages, Alzheimer but no records of the association have been studied.

The FDA has approved Bluetooth technology for use by consumers without any regulations or premarket testing, which is exactly how cellphones were approved. According to the FDA, “The majority of studies published have failed to show a connection between exposure to radiofrequency from a cellphone and health problems”

“At this time, we do not have the science to link health problems to cellphone use. Scientific studies are underway to determine whether cellphone use may cause health effects,” as per the Centers for Disease Control and Prevention. Federal Communications Commission says, “There is no scientific evidence that proves that wireless phone usage can lead to cancer or a variety of other problems, including headaches, dizziness or memory loss.”



So far, there has been no scientific proof to establish that using Bluetooth headsets cause any damage to the head or the body in general. As you know, prevention is better than cure. In order to keep the distance from the likely attendant danger, the Bluetooth headsets should be best avoided. Better still, you should use it moderately. This way, you will have nothing to worry about even if it is discovered in the future that people who have exposed themselves to it are likely to develop some strange disorders.
