Free radical formation can take place in various ways, including ultraviolet light, drugs, lipid oxidation, immunological reactions, radiation, stress, smoking, alcohol and biochemical redox reactions. Antioxidant defense systems exist in order to keep free radical formation under control and to prevent their harmful effects on the biological system. These reactive oxygen species can damage cellular components such as proteins, lipids and DNA.
Despite being essential for life, oxygen molecules can lead to the generation of hazardous by-products, known as reactive oxygen species (ROS), during biological reactions. Electromagnetic fields (EMF) have various chemical effects, including causing deterioration in large molecules in cells and imbalance in ionic equilibrium. However, their deleterious effects on the body, particularly on the nervous system, are well known. Technological devices have become essential components of daily life.
