The human brain is most exposed to high frequency electromagnetic fields (RF-EMF) when it is talking on the ear with a mobile phone. However, studies analyzing health effects have not yielded clear results so far. This is taken from a Thursday press release from the Swiss Institute of Tropical Health and Public Health (Swiss TPH).

A research team led by Martin Röösli of Swiss TPH investigated the relationship between mobile phones and the memory of adolescents. 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.
Abstract Shape Memory Test
More than 700 students aged 12 to 17 were recruited and followed for one year. They came from rural and urban areas of German-speaking Switzerland. In the work of the research group Röösli add a survey on the use of mobile phone and data collected objectively from mobile operators, confirming the results of 2015: The exposure of the brain to radiation cell phones for a year can have a negative impact on development Have memory. This was tested with a computerized test, in which young people had to remember abstract forms
Probably a connection
Figurative memory is mainly located in the right hemisphere. In fact, the influence of radiation was more pronounced among teenagers who were also using their cell phones on the right side of their head, according to researchers from the journal Environmental Health Perspectives.
"This suggests that the electromagnetic energy absorbed by the Röösli brain is cited in the message
Additional research is needed
Sending SMS, playing games or browsing Internet, on the other hand, only cause a low level of radiation and have no impact on memory performance., There were no significant correlations in verbal memory tests to which adolescents were subjected.
According to the researchers, further investigations are needed, particularly to rule out other factors that might play a role. "For example, the results of the study may have been influenced by puberty, which affects both the use of the mobile phone and the behavior of participants and their cognitive abilities, "says Röösli
. use the speaker. ommended with low energy quality and maximum performance of the mobile phone to minimize risks to the brain.
