The main health hazard posed by Bluetooth headphones is that they emit electromagnetic waves in the immediate vicinity of the brain. First of all, this concerns "replicas" with high-quality headphones, the associate professor of the Department of Informatics of the PRUE G.V. Plekhanova Alexander Timofeev.
"If we assume that radio waves have an electromagnetic basis for their work, then there is definitely harm. In humans, the activity of the nervous system also has electromagnetic currents, and the number of people suffering from magnetic oscillations of nature is only increasing," he said.
Even in the last century, scientists came to the conclusion that there is an effect of electromagnetic frequencies on food and organics. Already in forty countries, scientists indicate that wireless headphones can cause brain cancer. The fact is that Bluetooth is a source of a dangerous electromagnetic field, which in its properties is comparable to microwave radiation. And such radiation directly next to the brain is harmful, the expert pointed out.
At the same time, talking about harm statistics is also unequivocally difficult, since there is little relevant data, and technologies are constantly being improved. “I think that in the near future new technical solutions will surely appear that can improve the quality of work without causing even the slightest harm to human health,” he suggested.
Today, the most serious danger is the mass distribution of different replicas for "high-quality" headphones. It is from the replicas that hearing and health suffer. In addition, it is important to take into account that different countries have different standards for attitudes towards both health and the production of electronics. Therefore, manufacturers allow different levels of power for the interaction of headphones with devices and a person.
In general, the Bluetooth standard has a low emissivity for human health and has long been approved in the world. Therefore, it has become widely used for data and voice transmission. In particular, the technology is being used in computer mice, headsets or music systems to replace wired cables.
"At the same time, the class of wave propagation is different. Devices that have a minimum range of exposure are as safe as possible. In the case of headphones, you need to look like this: put the gadget on the table and, wearing headphones, move away from it. If at a distance of several meters the signal becomes weak, then the device is as safe as possible, "the expert concluded.
