EMF in Personal Devices & Wearables

  • -These are the devices that travel with you everywhere-in your pocket, on your wrist, in your ears, and on your lap.
  • -Personal devices and wearables represent your most intimate EMF exposure because they're designed to stay close to your body throughout the day.
  • -Your smartphone radiates radiofrequency energy just inches from your brain during calls, your laptop emits magnetic fields directly onto your lap, and your wireless earbuds transmit Bluetooth signals inside your ear canals.
