The World Health Organization (WHO), states there are no adverse health effects which have been linked with exposure to wireless technologies. Limited studies have been carried out using the 5G frequency, hence there is not enough evidence that there are major health effects due to 5G radiation.
As of now tissue heating poses a health effect, however as long as the overall exposure remains below international guidelines, there should be nothing to worry about. WHO is conducting a health risk assessment covering the entire radiofrequency range, including 5G. This assessment will be published in 2022
, so if you’re interested in that do stay updated with WHO.
