Schumann Resonator

A very important point to be aware of is that this resonated radio from lightning is a vanishingly small component of the electromagnetic spectrum to which we're all naturally exposed. The overwhelming source is the sun, blasting the Earth with infrared, visible light, and ultraviolet radiation. All natural sources from outer space, and even radioactive decay of naturally occuring elements on Earth, produce wide-spectrum radio noise. Those resonating in the Schumann cavity are only a tiny, tiny part of the spectrum.

Nevertheless, because the Schumann resonance frequencies are defined by the dimensions of the Earth, many New Age proponents and alternative medicine advocates have come to regard 7.83 Hz as some sort of Mother Earth frequency, asserting the belief that it's related to life on Earth, despite its being so tiny and lost among all the other, stronger parts of the electromagnetic spectrum. Often we find that New Age beliefs are often based more on what seems emotionally satisfying than on sound science.

The most pervasive of all the popular fictions surrounding the Schumann resonance is that it is correlated with the health of the human body. There are a huge number of products and services sold to enhance health or mood, citing the Schumann resonance as the foundational science. Before looking at some of these claims in detail, it's noteworthy that neither Schumann resonances, electromagnetic radiation, or the Earth's ionosphere are mentioned in any medical or anatomical textbooks. There is no detectable or theoretically predicted relationship between either ELF radio or the number 7.83 and the health of human body.
