It's so normalised that you become an outlier if you don't use these things. The companies selling these products have an interest in ignoring any harms they pose.

I recently stopped using AirPods and got wired earbuds. One extra benefit: no more charging or connectivity issues!

People love their wireless headphones. In my job at the fiat mines, everybody has their headsets on when joining remote meetings, even if they’re at home. I’m the only one who just uses the laptop speakers and mic.

That's a rather ridiculous analogy, it's like claiming that if you drink a whole water tank you will die therefore water is dangerous and you should avoid it. Yeah, Bluetooth and microwave ovens use the same frequency (2.4 ghz), but the similarities end there, wireless devices use very low power, Bluetooth devices are mostly between 1 and 100 milliwatts, while microwave ovens go 700 ~ 1000 watts, meaning BT devices emit at most 0.001% of what an oven does. Dosages must always be taken into consideration.

I’ve gone wired headphones.. always used speakerphone. Solid advice.

This I agree with wholeheartedly. Sure, they can be dangerous if used too much, but I rarely do some of that stuff anyway.

Sounds to me like you've already got brain damage. How far do microwaves penetrate your food? How strong are they? How strong is the signal from wearables? How far will it penetrate your head? There's a disturbing lack of critical thinking out there these days, and way too much group think.

Water molecules have natural rotational and vibrational modes in the microwave frequency range. WiFi and Bluetooth use this range too. Microwaves heat food by matching the frequency of water molecule motion, causing them to rotate and heat up. This heating effect is a thermal effect, they cannot ionize atoms or molecules directly. Higher frequency electromagnetic waves carry more energy per photon, which can make them more dangerous in terms of ionizing radiation (like X-rays or UV light) that can damage DNA and cells. Lower-frequency microwaves require much higher intensities to cause harm, and only through heating.

At 100mW of transmit power, probably less than 20% getting absorbed due to the spread, you are only getting 20mW. A 1x1 cm area under the sun is receiving 5x the energy. Not to mention your body is also heating up itself, soo…

20ghz and 80ghz microwave frequencies do have ionising effects though. starlink uses both of these i believe, and generally they have been restricted to military uses. one ionises oxygen and the other ionises something else, i forget. also, microwaves do not only interact with water, they interact with all OH- and H+ ions as these are basically water that has temporarily divided into two parts with teh electron on the base side. so they additionally interact with and cause extra heating to all kinds of salts because not only are they flipping the water and hydronium/hydroxyl ions they are inducing current in the salts, potassium, sodium, magnesium, calcium. it's quite an interesting subject, actually, microwave chemistry. the combination of ion exchangers and salts enable inducing electrons to cause chemical reactions at much lower temperatures than normal. but that's not tinfoil hat stuff. and what do you think is in our skin all over the place, all throughout the volume of our bodies that microwaves penetrate (they pass straight through the fat layer of the skin and go usually an inch or so deeper except to bones where they tend to reflect), mostly, lower frequencies like used in wifi and ovens they penetrate bone quite well and bones are full of our immune system too, and lots of salt ions around. i dunno why this is never mentioned. microwaves aren't ionising so they aren't gonna probably cause cancer, at least not directly with a person whose body isn't full of mercury, lead, cadmium, and other heavy metals, in which case it will, because the electrons will induce oxide radicals more rapidly than if there was no heavy metals in the body. microwaves induce current in metals. you should also read about and maybe watch some cool experiments, like making ball lightning, or using iron to get heat to cast silver or other relatively soft metals like tin and lead, heated by the microwave. the effect here caused by resistance of current, rather than ions being induced to oscillate their electrostatic poles. anyway, i forgot all this stuff, it's been some years since i thought much about microwave chemistry and metallurgy. if you read about it you'll see what i mean. ionization of water, sure, it doesn't do that. but it definitely looses electrons in many kinds of metallic based materials including most of the salts that our bodies are full of. mostly yes, this is just heat induction but some organs and structures are just the right size and full of these ions to get tuned and induce current, like the metallurgy and ball lightning experiments you can do (those use iron, btw) and speaking of iron, there is an awful lot of that in our skin as well. especially in vessels that are around the same as the wavelengths of some bands of microwave radio. you probably also know that millimeter waves, which are used in 5g radios and wifi6 at higher voltages are used in directed energy weapons that cause acute pain that feels like you are burning when pointed at your skin. there was cases of birds, also, in early tests of 5g radios that caused internal ruptures in small birds that i read about happening in the netherlands. oof, now i remember why i have earthing mat under my desk and sheet on my bed, and why i try to avoid having microwave radios around. in my case, my health issues are more about allergies but i'm sure that extra electrons floating around isn't gonna help things either.

Thanks David. Will take a couple reads and some research to understand.

yeah, ionization is literally defined as adding or taking electrons from something. so although microwaves don't ionize water, they ionize metals, if the metallic particles have some level of conductivity between them and form a body of sufficient size to tune to the radiation, acting as a receiver, and the electrons are then absorbed into surrounding tissue, and other things like oxygen or heavy metal particles, reducing them and making them active. i personally don't see the value in most applications of microwave radios. i saw a great saying on an antique phone in Funchal that said that when phones were tied to the walls we were more free. i prefer desktop computers and when i walk out of the house i'm offline. offline time has become so scarce people don't realise how valuable it is. you can think.

also, it's pretty illogical talking about "ionizing water" because water IS ions. anything that dissolves in water is ionized by the water. i think people have a mixed up perception that there is some connection with nuclear decay radiation and microwaves. there is not. most of what comes out of radiactive decay is mostly fragments of nuclei, alpha and beta particles, protons, neutrons. these cause cancer because they readily break anything they hit, especially DNA and proteins.
