Earth Resonances

A primary Earth field-line resonance is said to be around 0.1 Hz, matching coherent human heart rhythms. Schumann resonances are described as resonances in the cavity between Earth's surface and the ionosphere. Field-line resonances are described as vibrations of Earth's magnetic field lines caused by solar wind. Human physiology is said to be affected by disturbances in Earth's magnetic field, including those associated with solar flares. The article warns that popular Schumann resonance claims are often exaggerated or inaccurate. The first Schumann resonance is described as about 7.83 Hz, with additional resonances overlapping brainwave frequencies.
