Atmospheric Aerosol Burden and Human Biological Resilience - A Translational Analysis of persistent Nanoparticulate stressors and the application of Ayurvedic protocol

ABSTRACT Background - The progressive intensification of global aviation traffic and the advancement of proposed Stratospheric Aerosol Injection (SAI) programs have raised legitimate scientific inquiry into the biological consequences of chronic human exposure to atmospheric particulate matter, metallic nanoparticulates, and engineered aerosol compounds. While SAI is primarily framed as a climate intervention strategy, its potential health implications — encompassing neuroendocrine disruption, neuroinflammation, respiratory immunotoxicity, and systemic oxidative burden — warrant systematic translational investigation. Methods - This narrative-translational review integrates peer-reviewed literature from environmental toxicology, neuroendocrinology, respiratory immunology, and classical Ayurvedic pharmacology (2000–2025). Key databases searched include PubMed, Scopus, and Web of Science. Ayurvedic textual sources (Charaka Samhita, Sushruta Samhita, Ashtanga Hridayam) were consulted for contextual integration of traditional frameworks. Results - Documented and modeled atmospheric aerosol components (aluminum oxide, barium titanate, sulfate aerosols, and ultrafine particulates) exhibit mechanistic pathways toward Hypothalamic-Pituitary-Adrenal (HPA) axis dysregulation, Blood-Brain Barrier (BBB) permeabilization, microglial neuroinflammation, and trained innate immune dysfunction. Concurrently, classical Ayurvedic Rasayana botanicals — including Withania somnifera (Ashwagandha), Bacopa monnieri, and Ocimum sanctum (Tulsi) — demonstrate evidence-supported neuroprotective, adaptogenic, and immunomodulatory profiles. Panchakarma biotherapeutic procedures, particularly Nasya (nasal oil administration) and Virechana (therapeutic purgation), offer mechanistic analogues to modern chelation and enterohepatic detoxification strategies. Conclusion: this paper proposes an integrative model in which validated Ayurvedic phytotherapeutic protocols may serve as biologically grounded interventions for the mitigation of environmental aerosol-induced physiological burden. Further rigorous clinical validation is required. The translational framework presented here establishes a scientifically defensible bridge between classical Ayurvedic toxicology (Garavisha) and modern environmental health challenges.
