Plain English Summary
Turkish researchers exposed rats to Wi-Fi radiation (2.45 GHz) for one hour daily over 30 days and found it caused oxidative stress in the eye lens, similar to cellular damage from aging or toxins. When rats were given melatonin supplements, the antioxidant significantly reduced this Wi-Fi-induced damage. This suggests that common Wi-Fi exposure may harm delicate eye tissues, but natural protective compounds could help defend against such effects.
Why This Matters
This study adds to growing evidence that Wi-Fi radiation can trigger oxidative stress in sensitive tissues like the eye lens. The 2.45 GHz frequency used is identical to standard home Wi-Fi routers, making these findings directly relevant to daily exposure. What's particularly significant is that melatonin supplementation provided measurable protection against the Wi-Fi-induced damage. The eye lens is especially vulnerable to oxidative stress because it lacks blood vessels to clear away damaged proteins, making any protective effect noteworthy. While the researchers described the effects as 'poor' (meaning mild), even subtle oxidative damage can accumulate over time in tissues that don't regenerate.
Exposure Information
Specific exposure levels were not quantified in this study. The study examined exposure from: 2.45 GHz Duration: 60 min/day for 30 days
Study Details
The present study was designed to determine the effects of Wi-Fi exposure on the lens oxidant, antioxidant redox systems, as well as the possible protective effects of melatonin on the lens injury induced by electromagnetic radiation (EMR).
Thirty-two rats were used in the current study and they were randomly divided into four equal groups...
Lipid peroxidation levels in the lens were slightly higher in third (Wi-Fi) group than in cage and s...
There are poor oxidative toxic effects of one hour of Wi-Fi exposure on the lens in the animals. However, melatonin supplementation in the lens seems to have protective effects on the oxidant system by modulation of GSH-Px activity.
