Sunrise and sunset mark dramatic changes in the electromagnetic environment of Earth. These transitions are known to influence circadian rhythms in both humans and nature. During these times, the angle of sunlight alters the photonic input to the atmosphere, resulting in changes in light wavelengths, electromagnetic fields, and ion concentrations.
Scientific studies confirm that the ionosphere is most active during these transitional times. The Earth’s ionosphere is a layer of the upper atmosphere filled with charged particles (ions) created by solar radiation. At sunrise, the ionosphere rapidly becomes charged; at sunset, the ionization rate decreases sharply. These shifts create natural windows where energy fields fluctuate more dynamically than at any other time of day.
