While I don’t think the paranoia around 5G is justified, this isn’t an appropriate comparison.
Humans have a barrier, known as the “skin”, that’s designed to block the electromagnetic radiation from the sun and repair the damage it causes. Many of us even have an extra protective compound in us known as “melanin”. Nevertheless, damage to this barrier from the sun is responsible for causing many cases of cancer and people often wear protective compounds, known as “sunscreen”, to reduce cancer risks by blocking out the most dangerous ionizing radiation.
