Do I think we are being exposed? Yes. Do I think it matters in the grand scheme? Not likely.
I live a fairly "clean" lifestyle; at least in the areas I can control. I eat clean as much as possible, never buy factory farmed meats/dairy/eggs, or processed foods, don't drink out of plastic water bottles unless I have no other option, don't store food in plastic, rarely use foil, etc.
I'm also extremely sensitive to things, and have been unable to use some of the bigger/heavier apple watches due to a burning feeling going up my arm (most likely the way they press on a particular nerve, but it's something I've posted about here), couldn't use the XS Max due to headaches, and, when I use my iPP sitting down and put it on my legs, I do sometimes have a burning sensation (and it's NOT because the iPad is warm). I also get pain in my ears when I use my Airpods (which, admittedly, I rarely wear because of that). I'm fairly sure I am just hyper-sensitive to certain things.
That being said, I wear my Apple watch most of the day every day, but I don't sleep with it on (I would if I needed to do sleep tracking or heart rate tracking or something, but as a rule, no - mainly because I just don't like sleeping with anything constrictive on me at all).
I've never carried my phone on me, and the watch actually makes it even easier to leave the phone farther away. I DO sleep with the phone fairly close by because I use the alarm on it.
I guess with all the things I try to be careful with, I just figure these are things I can't really avoid. Tech is here to stay, and in order to keep up with things, it's a bandwagon I'm gonna have to be on. No I probably don't need an AW to stay on top of things, but it's convenient for me in so many ways, and I'm so used to it that IDK if I'd want to NOT have it. I just try to keep a balance.
