With the increasing use of modern technologies that rely on radio waves, microwaves and other segments of the spectrum of non-ionizing radiation in modern world, there is growing skepticism about the safety of this type of radiation for human health. Non-ionizing radiation may not have such severe consequences that can be noticed soon, as it is in the case of ionizing radiation, but it can cause effects such as oxidative stress that greatly affects many types of tissues and organs, including the nervous system. Given that the nervous system is responsible of coordinating the work of all other systems in the body and the functioning of the body as a whole, it is not surprising that discoveries describing the influence of a substance or phenomenon, arouse great curiosity and interest in public. Cognitive abilities that help us perform everyday tasks, from simple ones like reading and listening to complex ones such as solving certain problems and creating new inventions, are an important aspect of human life, and it is in the interest of every person and society to develop them for great benefit, which they can bring us. This paper highlights some of the previous discoveries about the effects of nonionizing radiation on cognitive abilities.
