Tahir E, Karadayı AA, Gürgen SG, Engiz BK, Turgut A · 2024

Researchers exposed pregnant rats and their newborns to WiFi radiation at 2.45 GHz during pregnancy and after birth, measuring hearing function and examining inner ear tissue. They found that exposure levels of 5 V/m and higher caused hearing loss, while 10-15 V/m triggered significant cell death in the cochlea. The study demonstrates that even relatively low WiFi radiation levels can damage the delicate structures of the inner ear.

Impact of specific electromagnetic radiation on wakefulness in mice

Deng H, Liu L, Tang X, Lu Y, Wang X, Zhao Y, Shi Y · 2024

Researchers exposed mice to 2.4 GHz electromagnetic radiation (like WiFi) with different pulsing patterns to see which characteristics disrupted sleep. They found that specific modulation frequencies, carrier frequencies, and pulse shapes all influence how much EMF exposure keeps mice awake. This helps explain why certain wireless devices may be more disruptive to sleep than others.
