The effects of increased technology use on people’s mental and physical well-being are a topic worthy of study, given the trend toward ever-greater use of such tools. The purpose of this narrative review was to determine the impact of technology on health and happiness. To ascertain the effects of technology on electromagnetic radiation (EM), posture and mobility, sleep disturbance, psychological stress, and well-being, the authors conducted a literature review of PubMed and documents from the World Health Organization, the Department of Defense, and the Centers for Disease Control and Prevention. Approximately 45% of studies reported negative effects from EM, while 55% reported no effect. Radiated electromagnetic energy (EM) at radio frequencies (RF-EM) may impact immature and fibroblast cells more. The use of electronic devices was linked to a diminished ability to concentrate, dizziness, and disturbed sleep. The use of social media is linked to the development of addiction in as many as 33% of users. Observed effects appear to be dose-dependent and more pronounced at younger ages. Sleep quality, mental health, and cognitive performance are all negatively impacted by excessive screen time. Seeking professional counseling, reducing time spent on social media, and eliminating its use in the hours leading up to bedtime have all been shown to lessen or prevent these consequences. Many EM’s effects are still up in the air, but researchers do know that RF-EM is on the WHO’s list of possible carcinogens.
