Welcome to the world of hypersensitivity to wifi / bluetooth. Unfortunately, most will try and gaslight into thinking you're crazy and it's all in your head. But as you know, your symptoms are 100% real.
I've been sensitive to wifi/bluetooth for over a decade, but I find bluetooth to be a lot worse than regular wifi. If I put in some bluetooth headphones, I will feel like throwing up in under a minute. I also don't use wifi in my home because of this, I use ethernet cables.
Fitbit uses wifi and bluetooth, but it's going to be mainly the bluetooth imo which is causing the nausea.
Unfortunately science has a lot of catching up to do with recognising what's going on here, until they do, non-electrosensitive people (which is the vast majority of the population) will think you're crazy. imo some corporations probably know about this but they have too much at stake to make their findings public, and they can make enough money selling to people who aren't sensitive to the immediate effects. But the way I see it, we're like the canary in the coal-mines. People who aren't sensitive are probably having negative effects, it's just that their body doesn't alert them. So whatever damage the bluetooth is doing to them is going unrecognised and may manifest as a health concern down the line. So I suppose we can count ourselves lucky that our bodies reject it straight away through nausea etc.
Something you'll hear a lot is "we're being bombarded by radiation all the time, cosmic background radiation, radio signals etc.".... well yes, that is true. But would you put your dog or cat in the microwave and turn it on for 10 minutes? Hey, it's just "radiation" and radiation is around us all the time! No, of course you wouldn't. Of course the power levels aren't the same as a microwave, but this is all so new, like the early days of cigarette smoking, we don't have longterm studies to know what's going on. It could be something to do with frequency resonance.. like how an opera singer can break a wineglass with her voice at a particular frequency, perhaps at certain frequencies, low power radiation from bluetooth etc. disrupts an organisms internal biological state through principles of resonance. Who knows! All we know is that we wear a bluetooth device and we feel nausea within a few minutes... this is an undisputed fact. Eventually the science will have our backs, again we're the canaries in the coal mines, until then just know you're not crazy.
