What is the Origin of Low Frequency Power Increase?

This terminology is borrowed from signal processing and bioelectrical measurement, where power spectral density analysis quantifies rhythmic activity. The focus on "low frequency" specifically points toward the rhythms associated with deep physiological rest and autonomic regulation. It is a measurable proxy for systemic deceleration.

What is the Mechanism of Low Frequency Power Increase?

The increase in low-frequency power often correlates directly with enhanced vagal efferent output, which slows cardiac rhythm and promotes gastrointestinal motility. This slowing allows for greater resource partitioning toward anabolic repair and detoxification pathways, as the energetic demands of sympathetic vigilance are reduced. Optimized mitochondrial function supports the metabolic efficiency necessary to sustain these slower, high-amplitude rhythms during recovery periods.

Low Frequency Power Increase

Meaning

An increase in the magnitude or coherence of biological oscillations occurring within the very slow frequency spectrum, often associated with deep relaxation, restorative processes, or specific stages of sleep, such as delta wave activity in EEG. In the context of wellness, this reflects enhanced parasympathetic tone and improved recovery states, contrasting with high-frequency sympathetic arousal patterns. This power increase signifies efficient energy utilization during rest.
