This sounds like fear-mongering nonsense. Bluetooth uses extremely low-power radio waves - way weaker than your WiFi router or cell phone. The "studies" claiming thyroid links are typically small, poorly controlled, or misinterpreted.

The radiation from Bluetooth is non-ionizing, meaning it literally can't damage DNA or cause the cellular harm described. Your microwave puts out thousands of times more electromagnetic energy.

Show me peer-reviewed evidence from major medical journals, not some wellness blog cherry-picking data.
