Overview

The Schumann resonances (SR) are a set of spectrum peaks in the extremely low frequency (ELF) portion of the Earth’s electromagnetic field spectrum. Schumann resonances are global electromagnetic resonances, generated and excited by lightning discharges in the cavity formed by the Earth’s surface and the ionosphere. The Schumann Resonance is caused by lightning in the atmosphere and has a stable frequency of 7.83Hz frequency falls within the range of natural human alpha brainwaves which is the optimum state for well-being and healing. Beyond being mere frequency peaks, Schumann resonances represent a phenomenon that integrates various Earth systems, atmosphere, ionosphere, and the lithosphere. The electromagnetic waves trapped in the ionosphere cavity can circle the Earth multiple times, slowly losing energy to absorption by the Earth and the atmosphere. The dynamic interplay of these waves can provide insight into climatic conditions, lightning activity, and potentially even seismic activity, making it a multi-disciplinary subject of study involving geophysics, meteorology, and atmospheric sciences. Alpha brainwaves are strongly linked to states of relaxed wakefulness and readiness. Their alignment with the Schumann resonances suggests an area where evolutionary biology and atmospheric sciences intersect. This alignment is not coincidental and humans may have evolved in harmony with these resonant frequencies, research could redefine our understanding of human health and well-being. One proposed mechanism is "neural entrainment," where external frequencies synchronise with brainwave patterns. If Schumann resonances can entrain brainwaves, they could have broad implications ranging from mood regulation to cognitive performance, a hypothesis around the role of ion channels in cellular function. Exposure to specific electromagnetic frequencies could affect the movement of ions across cell membranes, thereby influencing cellular behaviour and even gene expression.
