There aren't any common waves that could hurt your brain.
BUT
If you want to know about something invisible, that most people don't know about that can impact your health in persistent mild but still bad ways? Look up "infrasound" --
@futurebird @oldclumsy_nowmad@mastodon.social @muddle@infosec.exchange
it depends on the strength and type of signal, and how close you are to the source. an unshielded magnetron from a microwave oven will definitely cook you, including your brain. that's why there are warning signs to not stand in front of microwave radio dishes.

I wonder if one could channel the feeling many people have that "the world is slowly killing me somehow" into things like insisting that new highways don't send horrible rumbling sounds into surrounding neighborhoods?
But CO2 is also invisible and no one wants to care about that...

Sadly, between COVID and aging, there's probably going to be a wave of scam products in the future for brain fog. Nutropics, supplements, silver embedded clothing, just like copper was the woo-woo for arthritis.There are already hundreds of "brain fog" and "shortness of breath" and "fatigue" snake oils bc of the combination of widespread and surging LC and official/bipartisan minimizing of LC.

If I was just a skosh more evil I'd be selling all kinds of geegaws and doodads to the superstitious New-age Dark Age dipshits.
@GGMcBG @futurebird It is immoral to let stupid people keep their money.

@burnitdown @futurebird Its also interesting that different parts of the body are affected differently by microwaves. One of the more vulnerable parts are the eyes. So don't watch the food cook...

@clayfoot @futurebird Do they sell chaps to go with their chafes?

@adrake @futurebird @oldclumsy_nowmad I was thinking about that, and the fact that microwave ovens and wifi both use 2.4GHz. I did a quick search to try to find out the relative power levels. Ovens are easy: they're going to be around 800W~2kW. Unfortunately, the search results were suggesting WiFi pumps out 100--200W. Scary, if true. In fact, the actual power output is in the 20-100mW (*milli-*Watt) range.
I didn't really want to go there because it could play into the hands of those people that want to convince us that Wi-Fi (or 5G or whatever) is making us sick, but the 99.7% shielding figure is good to know. It would mean, roughly, that a 1KW microwave oven with proper shielding is pumping out around 10 times as much radiation as a local Wi-Fi router (1W compared to 100mW).
People pushing conspiracy theories about this is bad enough, but when search engines are promoting figures that are 3 orders of magnitude off, well... that's also very worrying. (and that's before we even get into LLMs...)
@muddle @futurebird @oldclumsy_nowmad the FCC limit on 2.4GHz transmitters is 1W for sufficiently spread-spectrum devices (including WiFi). The maximum emissions in any particular direction are capped at a level equivalent to a 4W omnidirectional antenna (this equivalent measurement is called EIRP). Most wifi devices operate well below that level since it's rough on battery life.
Microwave ovens are limited by FDA to leaking a max of 5mW/cm^2 from any point on the oven's surface (measured 2in away). That works out to be a little below the power density you get from a worst-case WiFi transmitter at 3 inches away.
The 99.7 number is the claimed shielding performance of the hat, not any regulations.

@oldclumsy_nowmad @futurebird I was going to look it up myself but realised the futility of it. IEEE is not a military organisation and real military standards tend to start with MIL, I think. Even if not, that whole line at the bottom screams fake.
@muddle @oldclumsy_nowmad @futurebird IEEE 299 is about standard measurement practice

@futurebird @oldclumsy_nowmad @muddle RF *can* hurt you if its high enough power, but that’s generally limited to labs and microwave ovens, not what’s emitted by cell phones
…or anywhere outdoors. you might get a sunburn
@cinebox @futurebird @oldclumsy_nowmad @muddle or worse...

@adrake @futurebird @oldclumsy_nowmad ah, I misread what you said about 99.7% initially. I didn't realise you were talking about the hat. So I guess I overestimated the effectiveness of the shielding and, hence, also overestimated the leakage
I also did look up some more reputable info on max wireless tx power and was surprised to find that in some countries it can even go up to 4W (which tallies with what you said):
Taken together, wifi and ovens seem to be roughly comparable rather than there being the orders-of-magnitude differences that I expected (with ovens emitting more radiation).
Thanks for the correction. I guess I'll have to retire my "but microwaves leak more energy" argument when dealing with (literal) tinfoil hatters...

Now, I'm not in favor of spam / scam callers...
But, I somehow feel less bad about the idea of someone selling snake oil brand snake oil clearly labeling the contents as snake oil (even if there are some outlandish claims) and letting fools and their money be parted?

I'm interested in noise pollution and light pollution. Light pollution is horrible for insects. (and birds) Noise pollution is bad for people.
We could have less loud, dark at night (but still safe) cities and towns.
@futurebird @oldclumsy_nowmad @Anke @muddle
Light pollution is bad for plants as well. Let’s see if I can find that link.

@SamanthaJaneSmith @futurebird the shielding is there so you don't cook yourself at all. without it, you would need to stand dozens of metres away to operate the microwave.

Do you think the people selling this are laughing at their customers or are they into it?
It's like a damn joke.
@futurebird They're selling it for $88? If they're not laughing, they're seig heiling at trump rallies.

@muddle @futurebird @oldclumsy_nowmad I think it's not accidental that they're comparable. Both are expected to be used by the general population with no safety training, so both should have limits that are safe under most circumstances.
Licensed users have different rules. Amateur radio operators are licensed to transmit at up to 1500W (!) on most of the 2.4GHz band, but they take on the legal burden of ensuring that whatever they do doesn't expose others to unsafe levels of emissions.
