EMF Home Safety: This AIRES Tech post is such a clear explanation of the difference between polarized man-made electro-magnetic fields (wifi, bluetooth, mobiles etc) and non-polarized natural electromagnetic fields (sunlight, cosmic background radiation etc), and why the distinction matters when we're considering how these fields may interact with biological systems.
This is based on the work of Panagopoulos, Johansson and Carlo, whose 2015 paper in Scientific Reports examined the role of polarization in the biological activity of electromagnetic fields.

Excerpt :
"All electromagnetic waves have a property called polarization. Essentially, the direction in which the wave's electric field oscillates.
Natural electromagnetic fields, like sunlight or cosmic background radiation, are unpolarized. Their electric fields oscillate randomly in every direction at once. There's no fixed pattern.
Man-made electromagnetic fields, from your WiFi router, your phone, your laptop, power lines, are polarized. They oscillate in a specific, fixed, organized direction. This is a direct result of how they're produced: by electrical circuits and antennas with defined geometry.
That difference sounds technical. But its consequences for biology are significant."
Natural EMF and man-made EMF aren't the same thing. The difference comes down to polarization — and it's why wireless devices affect biology differently.
