There's no way to escape EMF in modern life. Anywhere you go, you'll be exposed multiple cell towers, multiple CCTV systems, public wifi, people with cell phones sitting next to you, other electronic devices such as TVs, game consoles, laptops, monitors, space radiation, solar winds, etc. There's probably a risk associated with it as well, but trying to avoid it is becoming more difficult every day.
There's no concrete scientific evidence that having a cell phone transmitting next to your head or in your pocket causes cancer or any other disease, but it may be, although science has not demonstrated that yet. It is also possible that we live in a terrarium managed by species of giant lizards, but science has not proven that either.
To make matters worse, everybody wants to have more wifi coverage without blind spots in their houses, so we are all buying more and more powerful wifi routers, this means that you can manage to turn off yours but you can't escape your neighbors's.
Finally, many of us now use apple watches, Fitbits, Oura rings, etc, and have them emit EMF as close to our bodies as possible sometimes 24 hours a day.
In addition to EMF, there's light and sound pollution that is affecting the health of many people that cannot sleep well, leading to anxiety, depression, sexual problems. We have given up health for convenience in our modern life. There's no such thing as a free lunch.
I think if you're too concerned about this, you'd better call Saul.
