The rapid advancement of fifth-generation (5G) wireless communication technology has significantly enhanced global connectivity, enabling faster data transmission, low latency communication, and the expansion of digital infrastructure. Despite these technological benefits, increasing concerns have been raised regarding the potential health effects associated with prolonged exposure to radiofrequency electromagnetic fields (RF-EMFs) generated by wireless communication systems. This review aims to summarize current scientific evidence on the possible health implications of 5G radiofrequency exposure on respiratory diseases and to discuss the biological mechanisms that may be involved. Radiofrequency radiation used in wireless communication belongs to the non-ionizing region of the electromagnetic spectrum and does not possess sufficient energy to directly damage DNA or ionize biological molecules. However, several experimental studies have suggested that RF-EMF exposure may influence important cellular processes, including oxidative stress, redox signaling, and inflammatory responses. Increased production of reactive oxygen species (ROS) and alterations in antioxidant defense mechanisms have been observed in both in vitro and in vivo studies, indicating potential oxidative damage at the cellular level. These biological changes may contribute to mitochondrial dysfunction, tissue injury, and activation of inflammatory pathways associated with respiratory disorders such as asthma, chronic obstructive pulmonary disease (COPD), and pulmonary inflammation. Nevertheless, the overall scientific evidence remains inconsistent due to variations in exposure conditions, experimental models, and study methodologies. Therefore, further well-designed experimental, epidemiological, and mechanistic studies are necessary to better understand the relationship between RF-EMF exposure and respiratory health outcomes.
