>much higher radio frequencies (over 20 GHz, AKA millimeter wave or ‘mmWave’) Can anyone comment on whether this might have any effect on us? It makes me a bit anxious to see the huge list of wifi networks available where I am -- are we absolutely certain that all those signals don't have some sort of health impact?

Apparently the sun outputs radio waves in the THz-range, sub millimeter waves, so i dont think that this is anything to worry about. Also the strength of the radio waves comming from our devices is really weak, not at all in the suns level.

  Yeh but you see. The sun has existed for billions of years and we as humans have yet to adapt to it fully. There is a reason why we live in the shade and use sunscreen. Excuse me if I still feel skeptical about mmWaves..

  Light is 400,000 GHz to 800,000 GHz and has always existed on this earth. Man-made pulsed microwaves are 300 MHz to 600 GHz, and have never existed on this planet before. Both from a physics standpoint, as well as from a biological standpoint, they are not the same thing. Both are biologically active, but for one of them we have adapted (Vitamin D production and photosynthesis, for example), for the other we have not. From another perspective; the FCC limit for for microwave radiation is 10^18 times higher than natural background. That's a difference of a quintillion times. Backround levels (green), compared to current exposure: https://pbs.twimg.com/media/Dt2NMoJU4AE2oYY.jpg https://pbs.twimg.com/media/Dt2NMoJU4AE2oYY.jpg Therefore you can't really compare visible light exposure with microwave exposure. One has existed on the planet for billions of years, the other is completely artificial and man-made, and unlike visible light it penetrates tissues through the whole body, and there is no adaptation. https://www.thelancet.com/journals/lanplh/article/PIIS2542-5196(18)30221-3/fulltext https://www.thelancet.com/journals/lanplh/article/PIIS2542-5...

See for example https://www.ncbi.nlm.nih.gov/pubmed/25879308 https://www.ncbi.nlm.nih.gov/pubmed/25879308. I don't know why people are so care free about effects of nonionizing radiation. Current level of knowledge is in my opinion very primitive to even grasp the complex effects that may be happening. How many of us know anything about say voltage-gated calcium channels?
