This promotes relaxation and many other benefits related to pre-deep REM sleep.
Schumann resonances have been used to study the lower ionosphere on Earth.
Schumann resonance occurs between the surface of the Earth and the conductive ionosphere, and in our brain!
This is what it sounds like. Imagine PEMF pulses going through your body at that pulse rate also!
Our P4L-Home Clinic and PMT-500 have similar preset pulse rates. The PMT-120 and PMT-300 can be used on their lowest settings for similar pulse rates also.
