Tskaltubo and the Future of Structured Spa-Based Therapeutic Systems: Integrating Radon Balneotherapy, Rehabilitation, and Preventive Health in Evidence-Based Care

Abstract

The global rise in chronic non-communicable diseases, population ageing, and healthcare system fragmentation has intensified the need for integrated, non-pharmacological approaches to rehabilitation, recovery, and preventive health. Among these, spa medicine and balneotherapy have re-emerged as potentially valuable yet under-theorized and insufficiently standardized components of modern healthcare systems.

This commentary introduces the concept of structured spa-based therapeutic systems (SSTS) as a framework for understanding spa medicine as a coordinated, multimodal intervention rather than a collection of isolated treatments. SSTS combine natural therapeutic resources, standardized exposure conditions, environmental design, and behavioral structuring within a unified system of care. Using the Tskaltubo spa system in Georgia as a case example, this paper examines how such models can be critically evaluated and positioned within contemporary evidence-based healthcare.

Radon balneotherapy, a defining component of several spa systems, presents a unique clinical and regulatory challenge. While low-dose exposure has been associated with anti-inflammatory, analgesic, and immunomodulatory effects, radon remains a recognized carcinogen, raising important questions regarding dose–response relationships, cumulative exposure, and long-term safety. Current clinical evidence suggests meaningful benefits in selected conditions—particularly musculoskeletal disorders and rehabilitation contexts—but remains heterogeneous, methodologically limited, and insufficient for clinical standardization.

This paper argues that SSTS represent an underutilized, structured intervention platform with potential relevance for modern healthcare, particularly in rehabilitation, chronic disease management, and preventive health. However, their integration requires rigorous clinical validation, mechanistic clarification, and the development of dedicated regulatory frameworks, including standardized exposure protocols, patient selection criteria, and long-term monitoring systems. By bridging traditional spa medicine with contemporary scientific and health system perspectives, this work provides a foundation for the systematic and responsible integration of spa-based therapeutic environments into evidence-based care.
