I believe there is no dispute that sleeping beside your cell phone is not great for the constant cellular signal being so close to you. Same as having your phone attatched in pocket or by head all day long. I’m not a conspiracy theorist but between the cellular or even just blue tooth or wifi on the non-cellular version isn’t there some heath concerns since it is touching you and therefore very close to body for 8-16 or longer hours per day. I have been an owners of the Apple Watch version 2 and 4 and love it-but I fear that in the future we may find out these devices emit signals so close and so long during day that theee may be implications which haven’t fully been explored since there hasn’t had time for long term studies yet. Any thoughts? Should we curtail our use of smart watches that are attatched to our person connected to wifi or Bluetooth or even cellular?? Should I be putting the watch on airplane nose some or most of the day? Any other concerns about years of wearing these all day??
