About Bluetooth Devices EMF

  • -Your Bluetooth earbuds, wireless mouse, and smartphone are constantly communicating through radiofrequency (RF) electromagnetic fields in the 2.4 to 2.5 GHz range.
  • -While these devices have revolutionized how we connect and communicate, they also represent one of the most intimate sources of EMF exposure in our daily lives-often positioned directly against our heads, in our pockets, or on our bodies for hours at a time.
  • -Put simply, Bluetooth technology works by transmitting data through pulsed radiofrequency signals, and your body absorbs a portion of this energy whenever these devices are active.
