EMFs didn’t used to be a problem (electromagnetic fields) but they didn’t used to be so many or so powerful.

Our cellphones, microwaves, Wi-Fi routers, computers, and other appliances like Google minis and Alexas’ send out a stream of invisible energy waves that some experts are concerned about. Should we be concerned?

Since the beginning of the universe, the sun has sent out waves that create electric and magnetic fields (EMFs), or radiation. At the same time the sun sends out EMFs, we can see its energy radiating out. This is visible light.

At the turn of the 20th century, electric power lines and indoor lighting spread across the world. Scientists realized that the power lines supplying all that energy to the world’s population were sending off EMFs, just like the sun does naturally.

Over the years, scientists also learned that many appliances that use electricity also create EMFs like power lines do. X-rays, and some medical imaging procedures like MRIs, were also found to make EMFs. Please click link for more info then read photo beneath.
