Earthing, also known as grounding, is a practice that involves making direct contact with the Earth’s surface, usually by walking barefoot on grass, sand, or soil, or by using conductive mats or blankets that are connected to the Earth through a wire.

The scientific theory behind earthing is based on the fact that the Earth has a natural electrical charge, and that the human body can absorb and utilize this charge when in direct contact with the Earth’s surface. The Earth’s electrical charge is beneficial to the body’s natural electrical balance, which can become disrupted by exposure to electromagnetic fields, which our homes and environments are polluted with, and other environmental factors.

Studies have suggested that earthing may have a variety of potential health benefits, including:

  1. Reducing inflammation
  2. Improving sleep
  3. Reducing pain
  4. Improving circulation

What’s of particular interest is that geomagnetic fields are not simply “beneficial” for our health, but are in fact actually essential. NASA was able to determine that much of the deterioration of the health of their astronauts was because, in space, they were beyond the influence of the geomagnetic field. 

The electromagnetic field (EMF) of the Earth, the geomagnetic field that is, has a frequency range of extremely low frequency (ELF) waves, which are typically in the range of 0 to 100 Hertz (Hz). The most dominant frequency of the Earth’s EMF is – you guessed it – the Schumann resonance at roughly 7.83 Hz.

These are the ranges through which PEMF works, stimulating cellular health like we’ve evolved in nature, but with a stronger signal for therapeutic effect.
