zone creating beneficial ROS
Yes, controlled, low-dose ozone exposure creates beneficial, transient levels of
reactive oxygen species (ROS) and lipid oxidation products (LOPs), which act as signaling molecules that stimulate the body's endogenous antioxidant and immune defense systems.
This process is known as hormesis, where a mild, temporary stressor triggers a protective and adaptive response that ultimately restores bodily homeostasis
Mechanism of Action
When medical-grade ozone is administered into biological fluids (like blood or water overlaying tissues), it immediately dissolves and reacts with biomolecules, primarily polyunsaturated fatty acids (PUFAs), antioxidants, and proteins. This reaction produces short-lived ROS, such as hydrogen peroxide
and more stable LOPs, such as 4-hydroxynonenal (4-HNE). These molecules then function as key messengers in several beneficial cellular pathways:
Nrf2 Pathway Activation:
The mild oxidative signal from
and LOPs activates the nuclear factor erythroid 2-related factor 2 (Nrf2) pathway, the body's master regulator of antioxidant defenses. Nrf2 translocates to the cell nucleus and induces the transcription of powerful antioxidant enzymes, including superoxide dismutase (SOD), catalase (CAT), and glutathione peroxidase (GPx). This process enhances the cell's long-term capacity to manage oxidative stress and counteracts chronic oxidative damage.
Anti-inflammatory Effects:
Therapeutic doses of ozone help suppress the pro-inflammatory nuclear factor kappa B (NF-κB) pathway, which is often chronically activated in disease states. By doing so, ozone reduces the production of pro-inflammatory cytokines (e.g., IL-1β, IL-6, TNF-α), shifting the balance towards an anti-inflammatory state.
Improved Oxygenation and Circulation:
Ozone stimulates an increase in 2,3-diphosphoglycerate (2,3-DPG) within red blood cells, which enhances oxygen release to tissues. It also improves blood flow (rheology) and promotes the expression of growth factors like VEGF, which is crucial for wound healing and tissue repair.
Immune System Modulation:
Ozone can stimulate or balance the immune system, depending on the condition. It can enhance the activity of immune cells like macrophages and T cells to fight infections, or calm an overactive immune response found in autoimmune conditions.
Dosage is Key
The beneficial effects are critically dependent on a precise, controlled dose of ozone. Low to moderate concentrations induce the hormetic effect, leading to a stronger antioxidant and anti-inflammatory shield. In contrast, high or uncontrolled concentrations of ozone act as strong oxidants that can cause significant, indiscriminate cellular damage and toxicit
