Electromagnetic radiation can have various effects on human health, depending on the frequency and duration of exposure. Lower frequencies, such as those from radio waves, typically have minimal effects, while higher frequencies—like ultraviolet (UV) light—can cause skin damage and increase the risk of skin cancer. Ionizing radiation from x-rays and gamma rays can harm cellular structures, potentially leading to mutations and cancer. Prolonged or intense exposure to electromagnetic fields, such as from mobile phones, is still under research regarding its potential links to health issues like sleep disturbances and neurological effects. Understanding these effects is essential for establishing safety guidelines.
