Influence of Wi-Fi Exposure on Cognitive and Artistic Performances as well as Social and Individual Behaviour on a Class of Pupils in Elementary School

Abstract

During the experiments it was investigated the effect of Wi-Fi exposure on a class of pupils in the second grade primary school (8-9 years old). To the external Wi-Fi background level from the neighborhood and the Wi-Fi network in the school, an additional router installed in the classroom was used. The exposure effects were studied on pupil’s cognitive, artistic and creative abilities and also on their individual and social behavior through written tests, drawings and direct observations using qualitative and also quantitative methods. The examination took place on four dates, two dates with Wi-Fi exposure and two dates without Wi-Fi exposure. No significant effects were observed with the quantitative methods. There was only a trend towards fewer errors without exposure. The qualitative observation of behavior indicates an effect. Pupils in the control situation displayed a more relaxed behavior.
In the same setup with the identical class, the effect of a room harmonizer was tested independently a few months later. The situation was examined under Wi-Fi exposure with and without a room harmonizer. While the observation of cognitive performance and creative abilities showed no effect of Wi-Fi in our experimental design, there was a no-ticeable change in social behavior.
We strongly recommend further studies on the effects of radiofrequency electromagnetic fields on children, with particular emphasis on social behavior.
