The Earth’s magnetic field, a constant presence in our environment, has a subtle yet profound impact on human health. It operates at extremely low frequencies (around 7.83 Hz, known as the Schumann resonance) and low intensities (30−60 microTesla). Generated by electric currents in the conductive iron alloys in Earth’s core, this magnetic field protects us from a blast of solar particles (solar wind) that could literally obliterate life on Earth if allowed to enter our atmosphere (Figure 1). It also plays a crucial role in regulating our circadian rhythms and supporting overall cellular function. Our cells are used to living bathed in this interactive field of magnetism and electricity, and therapeutically, we can turn this into our advantage.
