Inadequate development of skills related to the safe use of electronic devices results in impaired daily routine and eating pattern, impairs the quality and duration of sleep, contributes to the development of internet addiction, determines the risk of health problems in users, and provides the basis for the development of prevention programs to be used at the population, group, and individual levels. The paper summarizes the data on the influence of electronic devices on the lifestyle and health of young adults. The review of scientific papers published in the international and Russian databases (E-Library, PubMed, Cyberleninka) in 2019–2023 is provided. The accumulated knowledge about the adverse effects of electronic devices on health will make it possible to use the findings to search for effective preventive measures and plan further scientific research.
