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.

Changes in Peripheral Blood Flow Produced by Short-Wave Diathermy

David I. Abramson et al. · 1957

This 1957 study by Abramson examined how short-wave diathermy (a medical heating treatment using radio frequencies) affects blood circulation in the arms and legs. The research used plethysmography to measure changes in blood flow after RF exposure. This represents early scientific documentation that radio frequency electromagnetic fields can produce measurable biological effects in humans.
