Are mobile phones harmful to our health and in particular to that of our brain? The subject has been debated for several years. A study has just answered it and the results are rather reassuring.

[EN VIDÉO] Interview: does neurofeedback make the brain work better? Neurofeedback offers a user the ability to observe their own brain activity. This non-invasive procedure has rather unexpected applications. Futura-Sciences interviewed, during her speech at TEDxCannes, Maureen Clerc, researcher at Inria (National Institute for Research in Computer Science and Automation), so that she could tell us about this technique in detail.
The mobile phones allow wireless communication. If we are now used to it, it is actually a real revolution. To achieve this feat, our telephones use waves radio transmitted by a network of fixed antennas (base stations). Radio frequency waves are magnetic fields low energy (between 450 and 2,700 MHz). The exposure decreases rapidly when the user moves away from the camera. For example, a person telephoning with a hands-free kit will be much less exposed than a person holding their telephone in their hand.
Do the waves act on our brain?
The waves emitted by our phones have the ability to penetrate a few centimeters into the cranial box when the user holds their phone close to their head. The temporal and parietal lobes of the brain are particularly exposed. There are of course manufacturing standards for mobile phones with thresholds ofemission not to exceed. Nevertheless, the biological effects of daily exposure are debated. Studies exist and most of them demonstrate that there is no link between normal cell phone use and the occurrence of brain cancer. But what is normal use? With unlimited plans and the development of teleworkcalls can last for hours.
A study over 20 years and 800,000 subjects
In order to see more clearly, a new study has been conducted and published in the Journal of the National Cancer Institute in March 2022. Data on 800,000 female subjects were collected over 20 years in the United Kingdom. Questionnaires were sent to participants at regular intervals to find out about their use of mobile phones. The questions were for example: “How many times a day do you use your mobile phone? or “How long have you had a cell phone?” or “How long do you call per week (in minutes)?” “. At the same time, data on their state of health were collected: age, socio-professional class, BMIconsumption ofalcohol and tobacco, onset of cancer (location and grade), possible death.
No significant difference could be demonstrated between the groups concerning the risk of occurrence of a brain cancerregardless of the type of cancer (gliomas, glioblastomas, tumors of the temporal and parietal lobes). This particularly serious study has the advantage of having been carried out prospectively, that is to say that the data on the use of the cellphone by the person were collected before the diagnostic of the tumors.
