Technology has become an integral part of our daily lives, as we rely on smartphones, computers, and wireless routers for work, communication, and entertainment. With the increasing use of these devices, concerns have emerged regarding the effects of electromagnetic radiation emitted by them on human health, both in the short and long term. To understand these effects scientifically, it is important to distinguish between different types of radiation. Mobile phones, routers, and computers emit non-ionizing electromagnetic radiation, which differs from ionizing radiation, such as X-rays, in its energy level. Non-ionizing radiation does not have sufficient energy to directly damage DNA through ionization. One recognized physical effect of radiofrequency radiation is its ability to cause limited heating of body tissues when energy is absorbed. The extent of this effect depends on the intensity and duration of exposure, as well as the surrounding conditions. Common symptoms such as headaches, eye strain, and sleep disturbances may be more closely associated with device-use habits than with the radiation itself. Exposure to light emitted by screens, particularly during the evening, may affect the secretion of melatonin, the hormone responsible for regulating sleep. Meanwhile, prolonged sitting in front of screens can contribute to neck and muscle pain, as well as tension headaches. Regarding the possible relationship between radiofrequency radiation and chronic diseases, including cancer, the issue remains under scientific investigation. The International Agency for Research on Cancer (IARC) has classified radiofrequency radiation as Group 2B, meaning “possibly carcinogenic to humans.” This classification reflects limited evidence and does not establish a definitive causal relationship. In conclusion, addressing concerns about technology requires reliance on credible scientific evidence while avoiding both exaggeration and underestimation of potential risks. Adopting healthy technology-use habits, such as reducing screen time before bedtime, maintaining proper sitting posture, and taking regular breaks, can help promote well-being and reduce the effects associated with excessive use of electronic devices.
