Mobile devices do not affect the brain of adolescents: scientists found evidence

Mobile devices do not affect the brain of adolescents

The scientists from the Barcelona Institute of Global Health conducted a study trying to discover the connection between the effects of mobile devices on the brains of the adolescents. Earlier, the assumption was discussed that the frequent use of gadgets affects their brain volume. However, a detailed study of the issue refuted the hypothesis. To study the relationship between gadgets and the brain volume of children from two years old, about 2500 children from 9 to 12 years old were involved.

Science is convinced that the use of mobile devices by children has undesirable health effects. Most previous studies have assessed the relationship between brain development and various sources of RF-EMF - gadget radio emissions. But clear ties were never found.

The integrative approach of the latest study took into account different sources of radiation, thereby giving a comprehensive assessment of the effects of RF-EMF on the brain of a teenager. During the experiment, parents of children filled out a questionnaire, noting how many hours a day their children use their mobile devices.

These included phone calls, on-screen actions, mobile phone antennas. Children had an MRI scan to determine the volumes of various parts of the brain. But the results surprised the experts. They did not reveal any connection between changes in the lobes of the brain and the use of gadgets.

An interesting fact was discovered: the structure of the brain involved in the coordination of memory and movements remembered the algorithm for using mobile devices - phones, laptops, players. If adults need a lot of time to learn a new mobile device, then for children that learning process takes a short period of time.

Another interesting observation is the use of wireless internet. The effects of RF-EMF on the brain at this point are much lower than during the phone calls. That is due to the distance between the head and the phone.

The authors of the study believe that the result should be interpreted with a great caution, because it is impossible to exclude other factors that were not found.
