Radio's affects on health is my guess. I've heard this at least. Radio tech can affect health but bluetooth is so low wattage I have very little concern about it. Even if there are negative health affects to cell phone and bluetooth usage most people are doing so many other things we know have more impact on health that I chuckle at this issue.

There's something interesting about humans. We tend to focus on what is out of our control and instead focus on things we can't control. I'm sure there is a name for this but its so weird. We know sugar is bad for our bodies yet most people consume insane amounts of it. Just reducing or eliminating this would make a massive impact on the health of most people. But no, lets focus on things we don't understand, which are in high dispute from both research and experts in the technologies.

also please add smartwatches. Most of them have Bluetooth always one. So try to sleep at night wearing your smartwatch to track your sleep cylce and it's beaming frequency waves every so often that it destroy your body cells. In the long run people get cancer. After searching for a month, I bought the Garmin Instinct 2, where you can enable or disable bluetooth and sync when YOU decide it.

Personal experience: I wake up in the middle of the night wearing a Huawei Fit 2. My arm was really itchy, a bit electrical, it stung me. Next day, I returned it.

It's not an extreme at all. Manufacturers in order to sell rather than taking into account those small details. They add marketing to say that it's not harmful, when true scientist (the ones with values and ethics) prove it damage cells into the body. Same is true with microwaves. We leave in a corrupt world, what did you expect, should I remind you.

Man I need to find the example but probably won’t be able to, but yes something about Bluetooth putting radiation in ur brain

More so added that one for the sake of dramatics 😂
