ضرر الـ«Wi-Fi» على الدماغ.. حقيقة أم مبالغة ؟

The President of the Marengo Asia Institute of Neurosciences and Spine in India, Dr. Praveen Gupta, revealed that most studies warning about the negative effects of Wi-Fi were conducted on animals, not humans, making their results non-generalizable. He explained that some experiments on mice indicated a potential impact on fertility, but human studies have not confirmed this. Experts pointed out that Wi-Fi signals rely on non-ionizing waves, which are much weaker than X-rays or CT scans, and do not have the ability to damage brain cells or alter DNA. According to scientific studies, no direct relationship has been proven between Wi-Fi exposure and the occurrence of brain tumors, memory loss, or neurodegenerative diseases. Although some research has recorded slight effects on brain waves during deep sleep, these changes are considered limited and clinically insignificant. Researchers believe that the deterioration in sleep quality is often linked to factors such as stress and device usage before bedtime, rather than the wireless signals themselves. Experts confirmed that modern medical devices like pacemakers and hearing aids are designed to operate safely in an environment filled with wireless signals, and leaving Wi-Fi connected at night does not harm the brain scientifically, but may indirectly help improve sleep by reducing late-night browsing.
