Do you have habit of running while keeping earphone? Do you talk ample on phone?
Temperature of ear lobes increases by 1 C when cell phone is used for approx. 20 minutes. 1 C is huge difference for body. And if it is repeated multiple times daily, it affects severely…
Effects?
Warm sensation ->tinnitus -> irreversible heat loss -> Ear Tumor
I have observed heavy Bluetooth users losing hair above ears(no research..just personal anecdotal observations)
Take care. Airpod or any such Bluetooth device or even direct usage of phone for longer period – Avoid.
PS: I work in IT. I use speakers. No headphone …forget about Bluetooth.
