Technological devices have become essential components of daily life. However, their deleterious effectson the body, particularly on the nervous system, are well known. Electromagnetic fields (EMF) have var-ious chemical effects, including causing deterioration in large molecules in cells and imbalance in ionicequilibrium. Despite being essential for life, oxygen molecules can lead to the generation of hazardousby-products, known as reactive oxygen species (ROS), during biological reactions. These reactive oxygenspecies can damage cellular components such as proteins, lipids and DNA. Antioxidant defense systemsexist in order to keep free radical formation under control and to prevent their harmful effects on thebiological system. Free radical formation can take place in various ways, including ultraviolet light, drugs,lipid oxidation, immunological reactions, radiation, stress, smoking, alcohol and biochemical redox reac-tions. Oxidative stress occurs if the antioxidant defense system is unable to prevent the harmful effectsof free radicals. Several studies have reported that exposure to EMF results in oxidative stress in manytissues of the body. Exposure to EMF is known to increase free radical concentrations and traceabilityand can affect the radical couple recombination. The purpose of this review was to highlight the impactof oxidative stress on antioxidant systems.© 2017 Saudi Society of Microscopes. Published by Elsevier Ltd.
