Wi-Fi radiation is harmful to human health
While some experimental and small-scale clinical studies report potential biological effects and health concerns associated with Wi-Fi and radiofrequency radiation, comprehensive reviews and regulatory evaluations emphasize that the current evidence remains ambiguous, often lacking definitive consensus on direct harm.
The provided literature presents a split picture. Several experimental studies and reviews report potential adverse biological effects of Wi-Fi and radiofrequency radiation on sleep, reproduction, and cellular parameters. Conversely, broad reviews and critical analyses highlight that human exposures remain within legal limits, findings are often ambiguous or inconclusive, and psychological factors or lack of direct clinical consensus challenge the hypothesis of widespread harm. Consequently, the evidence is best classified as contested.
Some experimental, animal, and in-vitro studies report potential biological effects associated with Wi-Fi radiation, while reviews note that current evidence remains ambiguous.

This study found that exposure to a 2.45 GHz radiofrequency device significantly reduced subjective sleep quality and altered EEG power density in healthy adults.

This review notes that most studies do not find exceedances of legal radiation limits and that existing research on Wi-Fi remains ambiguous regarding definitive negative health effects.

This commentary argues that electromagnetic hypersensitivity is largely unfounded from a purely electromagnetic standpoint and is better explained by psychological and cognitive hypotheses.
