Nature Exposure Pathophysiology Theory: A Systems Model for Chronic Pain, Mobility, and Emotional Regulation

Chronic pain, mobility impairment, and emotional dysregulation are not three problems. They are one problem expressed across different biological scales. Modern medicine treats them separately: pain to rheumatology, movement to orthopedics, emotion to psychiatry. The result is predictable, polypharmacy, contradictory treatment plans, and persistent functional decline despite guideline-adherent care. The underlying biology tells a different story. Central sensitization, autonomic dysregulation, HPA axis disruption, and chronic inflammation share molecular circuitry, neural architecture, and regulatory feedback loops. They are not comorbidities. They are co-expressions of shared pathophysiology. Nature Exposure Pathophysiology Model advances a rigorous, multi-scale systems framework that maps this shared pathophysiology from molecular mechanism to clinical intervention. Drawing on psychoneuroimmunoendocrinology, systems biology, environmental physiology, and attachment neuroscience, the model specifies how structured nature exposure simultaneously engages neural, autonomic, endocrine, immune, metabolic, perfusion, structural, tissue, functional, behavioral, environmental, and relational domains, producing multi-target biological change that pharmacological monotherapy cannot replicate. This is not a theoretical exercise. The volume defines a twelve-domain biomarker operating system with measurement protocols, clinical interpretation thresholds, and decision algorithms. It specifies a three-phase, biomarker-guided treatment protocol regulation, movement, integration, operating as a closed-loop adaptive system. It delivers a complete randomized controlled trial design, IRB-ready protocol, dataset architecture, and statistical analysis plan. And it maps the clinical decision-support platform, data pipeline, and scalable SaaS infrastructure required to translate this science into operational healthcare delivery. A companion volume to the Value-Based Outdoor Healthcare℠ framework, this work establishes the mechanistic foundation for a new category of clinically integrated, reimbursable care, where the outdoor therapeutic environment is not an amenity but a measurable, biomarker-driven intervention.慢性疼痛、运动功能障碍与情绪失调并非三种独立病症，而是同一病理在不同生物尺度上的不同表现形式。 现代医学往往将三者割裂诊治：疼痛转诊至风湿科、运动障碍归属骨科、情绪问题交由精神科。其结果不难预见：多重用药、治疗方案自相矛盾，即便遵循指南规范诊疗，患者的功能仍持续衰退。而深层生物学机制揭示了截然不同的真相：中枢敏化、自主神经功能失调、下丘脑-垂体-肾上腺（HPA）轴紊乱与慢性炎症共享分子通路、神经架构及调节反馈环路。三者并非共病，而是共享病理生理学机制的协同表达。 自然暴露病理生理学模型（Nature Exposure Pathophysiology Model）提出了一套严谨的多尺度系统框架，将共享的病理生理学机制从分子层面映射至临床干预环节。该模型融合精神神经内分泌免疫学、系统生物学、环境生理学与依恋神经科学的理论，阐明了结构化自然暴露如何同时作用于神经、自主神经、内分泌、免疫、代谢、灌注、结构、组织、功能、行为、环境与关系等多个领域，产生药物单一疗法无法实现的多靶点生物学改变。 这并非一项纯理论研究。该专著构建了一套涵盖十二领域的生物标志物操作系统，配套测量方案、临床解读阈值与决策算法。其明确了以生物标志物为导向的三阶段治疗方案——调节、运动与整合，该方案可作为闭环自适应系统运行。同时，它提供了完整的随机对照试验（randomized controlled trial, RCT）设计、符合伦理审查委员会（Institutional Review Board, IRB）要求的方案、数据集架构与统计分析计划，并描绘了将该科学成果转化为临床运营服务所需的临床决策支持平台、数据管道与可扩展软件即服务（SaaS）基础设施蓝图。 作为《基于价值的户外医疗（Value-Based Outdoor Healthcare℠）》框架的配套专著，本研究为一类新型临床整合式可报销医疗服务奠定了机制基础。在此类服务中，户外治疗环境并非额外便利设施，而是一种可量化、以生物标志物为导向的干预手段。
