Hypothesis
HBOT at 1.5 ATA for 60 min induces hormetic response via Nrf2 activation, enhancing endogenous antioxidant capacity without causing oxidative damage
This hypothesis posits that mild hyperbaric oxidative stress activates Nrf2-ARE transcriptional programs, upregulating SOD1, catalase, GPx1, and HO-1 without causing cumulative oxidative injury.

🧪 Overview
This hypothesis posits that mild hyperbaric oxidative stress activates Nrf2-ARE transcriptional programs, upregulating SOD1, catalase, GPx1, and HO-1 without causing cumulative oxidative injury. It provides the most direct framework for parameter optimization via dose-response mapping and represents the strongest balance of mechanistic plausibility and parameter tractability. The hormetic dose-window concept directly addresses the knowledge gap about optimal HBOT parameters.
