Interesting. I would like to see more research - especially with humans. That waves used in 4G cause harmful effects on humans was proved to be not true. But those mmWaves for 5G are much higher frequency, and they get absorbed by more materials. Perhaps by human body too? It wouldn’t be healthy to be constantly exposed to waves like that. I definitely would like to see more research in this.

Most, almost all animals are mostly water. About 2GHz you have a frequency that resonates with water, it's gets stopped by water, including rain. E.g. it's energy goes into the water, this is how the microwave operates. For this reason it's traditionally considers useless as radio transmission. And turned into a global free frequency span. Making this radio space used by all kinds of devices that you have at home. Wifi, Bluetooth, etc. There is tons of research of how radio and other waves effect the human body.

  Above 20GHz you mean.

    Nope, about 2ghz

      that was chosen to build smaller ovens, not because of a "resonating frequency".

    Microwave oven is about 2.45 GHz, and I agree it's not optimal for heating water. But the middle of the free 2.4GHz to 2.5GHz band.

      yes, but it has nothing to do with a resonance frequency.

  Seems like microwave energy going into water could be a problem if the water is in a gnat or moth or butterfly.

> But those mmWaves for 5G are much higher frequency, and they get absorbed by more materials 4G is on the order of 10^9 Hz (1 GHz), and 5G is on the order of 10^10 - 10^11 Hz. Both are non-ionizing radiation, and in the overall scheme of things, relatively close in frequency. Ionizing radiation causes cell mutation. It starts with UV radiation at 10^16 Hz. X-rays are around 10^18 Hz. We can't say with certainty that 5G can't possibly have some negative effects, but so far, we have no reason to believe it.

  You know the World Health Organization lists cell phones as "Possibly Causing Cancer in Humans" right? That's the world's leading authority on human health saying that. I don't care that technically speaking cell phones "can't" cause cancer because they are thought to be non-ionizing. That's just the same as all the other things in history that have been impossible until they've been done.

    WHO lists many many things as possibly being carcinogens. Remember that the world health organization had coffee listed as a possible carcinogen for 25 years before it was removed in 2016. https://www.wsj.com/articles/world-health-organization-to-drop-coffees-status-as-possible-carcinogen-1465946753 https://www.wsj.com/articles/world-health-organization-to-dr...

    From your perspective, I suppose everything is possibly carcinogenic since you don't care about whether technically speaking something "can't" cause cancer. I would give more credibility to the numerous scientific studies that have look at this than the words (that could be applied to literally anything) of some working group associated with The WHO. https://www.who.int/en/news-room/fact-sheets/detail/electromagnetic-fields-and-public-health-mobile-phones https://www.who.int/en/news-room/fact-sheets/detail/electrom...
