Abstract

Category: Neuroscience Tags: Wi-Fi radiation, neurobehavioral changes, oxidative stress, zebrafish, electromagnetic fields, non-ionizing radiation, public health DOI: 10.36948/ijfmr.2025.v07i04.52286 URL: ijfmr.com Overview The rapid development and use of wireless technologies have raised concerns about the possible harmful effects of long-term exposure to non-ionizing electromagnetic radiation (EMR). Wi-Fi routers are the most commonly used devices at households, offices, hotels, hospitals, airports, and train stations to provide wireless internet access to multiple devices. Therefore, prolonged exposure to EMR warrants thorough scientific investigation and risk assessment. Methods - Adult zebrafish were exposed to 2.45GHz Wi-Fi radiation for 4 hours daily over a consecutive 30-day period. - Neurobehavioral and brain oxidative stress parameters were evaluated post-exposure. Findings - Significant neurobehavioral impairments were observed in the exposed zebrafish. - Altered locomotion patterns were documented. - Decreased levels of the neurotransmitter acetylcholinesterase (AChE) were found. - There was a notable increase in oxidative stress in the brain tissue. Conclusion Further studies are needed to better understand the molecular mechanisms involved and to assess the broader implications for vertebrate neurobiology and public health. This study highlights a definitive connection between electromagnetic fields from Wi-Fi radiation and negative neurobehavioral as well as oxidative stress effects, signaling a safety risk that warrants additional research and precaution.

Main findings

Adult zebrafish exposed to 2.45 GHz Wi-Fi radiation (4 hours/day for 30 days) showed significant neurobehavioral impairments and altered locomotion. The study reports decreased acetylcholinesterase (AChE) levels and increased oxidative stress in brain tissue post-exposure.
