They are known to stimulate our cells, as mentioned in the video I posted on Baba. They suggest we need the ULF more, but I tend to believe we need both high and low. Maybe as we get closer to the third helix in our DNA we’ll need ULF more.
Extremely low frequency (ELF) is the ITU designation[1] for electromagnetic radiation (radio waves) with frequencies from 3 to 30 Hz, and corresponding wavelengths of 100,000 to 10,000 kilometers, respectively.[2][3] In atmospheric science, an alternative definition is usually given, from 3 Hz to 3 kHz.[4][5]
In the related magnetosphere science, the lower-frequency electromagnetic oscillations (pulsations occurring below ~3 Hz) are considered to lie in the ULF range, which is thus also defined differently from the ITU radio bands. Extremely low frequency Wavelength range 100,000 to 10,000 km, respectively
