About Laptops EMF

  • -Your laptop sits inches from your body for hours each day, emitting radiofrequency radiation from its WiFi antenna and extremely low frequency magnetic fields from its internal components.
  • -These emissions span a remarkably wide range, from 50 Hz power frequencies up to 5.8 GHz wireless signals, creating what researchers call a "mixed exposure environment" right on your lap or desk.
  • -What makes laptops particularly concerning from an EMF perspective is their proximity to your body combined with duration of use.
