High frequency electromagnetic fields can be detrimental to the development of memory performance of certain regions of the brain when using mobile phones. This was the result of a study involving nearly 700 adolescents

The most important source of exposure to the high-frequency electromagnetic field (RF-EMF) is the use of a mobile phone near the head. However, studies that analyzed the health effects of these fields have so far not yielded clear results, according to a statement from the Swiss Institute of Tropical Health and Public Health ( Swiss TPH).
A research team led by Martin Röösli has now studied the association between HF-EMF's exposure of cell phones and teenagers' memory. Scientists took this to a study published in 2015 in the journal Environment Environment. However, the new study included twice the size of the sample as well as new information on the absorption of electromagnetic radiation in the adolescent brain.
Abstract Shape Memory Test
More than 700 students aged 12 to 17 years were recruited observed. They came from rural and urban areas of German-speaking Switzerland. The work of the Röösli research group which, in addition to a mobile phone usage survey also collected objectively collected data from mobile operators, is the first epidemiological study in the world to estimate the cumulative dose HF-EMF in adolescents.
The results of 2015 were confirmed: the cumulative exposure to the HF-EMF of the adolescent brain over a year can have a negative impact on the development of their memory. This was tested with a computerized test, in which young people had to remember abstract forms.
Figurative memory is mainly located in the right hemisphere. The influence of radiation was indeed more pronounced among teenagers who also used their mobile phone on the right side of the head, as reported by researchers in the journal Environmental Health Perspectives.
"This suggests that electromagnetic energy is absorbed by the brain Röösli is cited in communication.
Further research is needed
Sending SMS, reading from games or browsing the Internet results in a low level of radiation and has no influence on memory performance., Also in verbal memory tests, which have also been subject to adolescents, no significant correlation was found.
It is still unclear to what extent the results are relevant in the long term.According to the researchers, further research is needed, especially to exclude d & # 39; Other factors that could play a role. "For example, the results of the study may have been influenced by adolescence, which affects both the use of the mobile phone and the participant behavior and their capabilities cognitive problems, "said Röösli. Reduce the brain, use headphones or speakers when on a call. This study, supported by the Swiss National Science Foundation (SNSF), was conducted by the Swiss TPH in collaboration with the European project Geronimo, which explores the relationship between HF-EMF and health. Belgian scientists participated in the calculation of the dose.
