The term Bluetooh describes a network technology developed for connectionless or connection-oriented point-to-point transmission of voice and data between two different digital devices. Nowadays it is increasingly used, either to connect it to our car and be able to receive calls and notifications, activate the browser or to listen to music using headphones. The truth is that it is a very convenient way to transfer data, but can it pose a risk to our hearing health?

Since its invention, many theories have emerged about whether the energy used by Bluetooth technology could harm our health, whether our ears or our brain, and even if there is a possibility that it may be carcinogenic. However, various investigations were responsible for removing all these doubts.
Effects on hearing
Regarding whether there is a possibility that Bluetooth technology could cause harmful effects on hearing, an Australian investigation conducted by the private Bond University confirmed that non-excessive use of Bluetooth headphones does not cause any problems. However, using them for very long periods and on a regular basis can cause various problems related to noise damage. In fact, it is a fact that the effects of prolonged exposure to loud noise on our ears and hearing organs are causing more and more diagnoses of acute and chronic acoustic trauma, derived from oxidative stress in neurons. In conclusion, the study indicates that as long as this technology is not used excessively, our hearing should not be affected.
Effects on the brain
Regarding the brain, the International Agency for Research on Cancer confirms that the electromagnetic frequency radio waves on which Bluetooth technology is based could be carcinogenic. However, only 10% of people reported a link between the use of this technology and brain tumors, with the majority reporting that they used the phone for an average of four to five hours a day to receive or make calls.
One of the most famous studies regarding the effects of Bluetooth on the brain is The Million Women StudyIn which 800,000 British women participated to assess the risk of developing brain tumors after seven years of using mobile phones and Bluetooth. The result was that in that time period a total of 3,268 cases of brain tumors were recorded, but no direct relationship was found to justify the appearance of tumors with excessive use of mobile phones.
Are Bluetooth headphones harmful to your health?
GAES, the leading company in the hearing correction sector in Spain, published several studies on its official website in which it stated that the radiation emitted from wireless headphones is less than the radiation emitted from the smartphones that we use daily, meaning that the power of these devices does not reach levels that may pose a danger. . However, they warn that if they are used for more than an hour a day listening to music at more than 60 percent of maximum volume, they can cause hearing problems in the long term.
