A Phase-Based Framework for Respiration: Linking Biological Oscillators and Environmental Variability

Abstract

Respiration and gas exchange are fundamental physiological processes that regulate metabolic homeostasis and autonomic function in living systems. Beyond their established biochemical roles, increasing evidence suggests that respiratory dynamics may also interact with environmental variability, including atmospheric and geophysical conditions, although the mechanisms and extent of such interactions remain under investigation.

In this study, we propose a theoretical framework that interprets respiration as a phase-modulated interface linking internal biological oscillators with external environmental dynamics. Within this formulation, respiratory activity is described in terms of phase relationships (Δφ), effective coupling strength (κ), and information-related variability (∇I), which can be approximated using measurable physiological and environmental proxies such as heart rate variability (HRV), respiratory rate, and environmental fluctuations.

Rather than asserting direct causality, this study integrates cross-domain observational evidence—including physiological synchronization patterns, behavioral responses in magnetosensitive species, and environmental variability—to examine potential associations between respiration and system-level coherence. Within this context, the circulation of key biogenic elements (carbon, hydrogen, oxygen, and nitrogen) is interpreted in terms of their roles in structural organization, energetic processes, and signal-related dynamics across biological and environmental systems.

Collectively, this framework provides a descriptive and hypothesis-generating model for analyzing respiration within a coupled organism–environment system. By situating respiratory dynamics within a broader phase-based context, the proposed approach offers a complementary perspective to existing physiological models and may support future investigations across biophysics, neurophysiology, and environmental health.
