What are differences and historical developments for teaching these ideas to breathing students?
The NormalBreathing became the first Buteyko course or breathing retraining course that introduced Grounding (Earthing) as a part of breathing retraining starting from about 2013.
In the 1960-70s, Dr. Buteyko and his colleagues discovered that barefoot walking is beneficial for breathing retraining. One of the written sources that mentions barefoot walking is in the article by Soulyagin S. S. Here is the reference:
Physical factors in DVBM treatment, published in Buteyko method. Its application in medical practice, ed. by K.P. Buteyko, 2nd ed., 1991, Titul, Odessa, pages 47-53.
However, their explanation of positive effects was based on the idea of nerve stimulation on the surface of the feet as the crucial or main effect of grounding. The idea of grounding the human body (physically or using electrical conductors, with Earth) appeared decades later when Clint Ober discovered and started to investigate effects of electrical grounding of the human body for health benefits (e.g., to reduce insomnia). Later, positive effects of nerve and muscle cells due to Grounding were found in clinical studies.
Teachers and students of the NormalBreathing course use a unique DIY Earthing (Grounding) method at night (or during sleep) that has these great advantages and benefits:
1) This DIY Earthing method is cheaper and simpler than any commercial (Amazon, etc.) grounding product
2) This device provides better grounding than any commercial product. It works as well as methods used for best clinical trials on Earthing.
