Red Light Therapy and Oxygen Therapy: Where They Overlap, and Where They Do Not
By Dr. Chris Cormier, DC The most common question I get after an EBOO consultation is not about EBOO. It is some version of: what else should I be doing alongside it? And more often than not, the thing people have already read about is light. Red light therapy has gone from obscure to everywhere in about five years, and anyone researching oxygen-based therapy runs into it within about ten minutes. So it is worth answering properly. Red light therapy and oxygen therapy are aimed at the same part of the cell by genuinely different routes — which is more interesting than it sounds, and which has some practical consequences for what to do first, what to expect, and what nobody can honestly promise you about combining them. They Converge on the Same Enzyme Inside every cell, mitochondria run an electron transport chain that produces energy. The last enzyme in that chain is called cytochrome c oxidase, and it is the point at which the whole process hands its electrons to oxygen. Two things are true about that enzyme at once. It is the main absorber of red and near-infrared light in human tissue. And oxygen is its substrate — the thing it needs in order to work at all. Which means light-based and oxygen-based approaches are not working on separate parts of the body that happen to both sound energising. They are arriving at the same enzyme from two directions: one delivering photons it can absorb, the other delivering more of the molecule it consumes. One of the better-supported proposed mechanisms for photobiomodulation makes that overlap explicit. Nitric oxide can bind to cytochrome c oxidase and sit where oxygen should be, slowing the enzyme down. Red and near-infrared light appear to displace it, freeing the site for oxygen again. If that is what is happening, then light is partly working by improving how well the cell uses oxygen it already has. But They Get There by Different Routes The difference matters more than the overlap when you are deciding what to actually do. Light is a local, surface-in intervention. Red light at around 660 nanometres works close to the surface; near-infrared at around 850 penetrates further. Either way, you are treating the tissue the light reaches. Depth is limited, and it falls away quickly with distance from the device. Oxygen-based therapy is a systemic, inside-out intervention. EBOO circulates your blood through filtration and oxygenation stages before returning it, so what changes is the circulating supply rather than one patch of tissue. Hyperbaric oxygen and exercise-with-oxygen approaches work on the same principle from different angles. So they are not substitutes and they are not really competitors. A panel will not do anything meaningful for circulating oxygen supply. A session of oxygenation will not deliver photons to the enzyme. They answer different questions. Does Combining Them Actually Do More? Here is where I have to be straight with you, on a page that could very easily be an argument for buying both. There is no meaningful trial evidence that combining red light therapy and oxygen therapy produces a greater effect than either on its own. The mechanistic rationale is reasonable — you can see from the section above why someone would expect the two to complement each other. But a plausible mechanism is not a demonstrated outcome, and nobody has run the studies that would settle it. What does exist is a reasonable literature on each separately, and it is uneven in both cases. Photobiomodulation has decent support for skin and wound healing, temporary musculoskeletal pain relief and exercise recovery, and much thinner support for systemic and cognitive applications. EBOO has a small, largely European body of work on ozone therapy generally and no high-quality trials on the specific applications people usually ask us about — something we set out in more detail in our articles on EBOO and detox and oxygen therapy for concussion recovery. Ozone therapy is also not FDA-approved for the treatment of any medical condition in the United States, and red light devices that hold FDA clearance are cleared for narrow indications such as temporary minor pain relief — clearance is not approval. If a clinic tells you the combination is proven to be more than the sum of its parts, ask them for the trial. There is not one. What Order Makes Sense in Practice Given all that, here is how I actually sequence it — as clinical reasoning, which is what it is, rather than as evidence. Foundations first, always. Sleep, hydration, breathing, daylight and movement within your capacity. These decide how much benefit anything else can produce, and they cost nothing. Someone sleeping five broken hours will get less from every intervention on this page than someone sleeping seven solid ones. Then light, because it is cheap and low-risk. A decent home panel used consistently is accessible to almost everyone, and it carries fewer suitability hurdles than any circuit-based therapy. There is a buying and dosing guide on BodyChargers, and the short version is that irradiance at a stated distance is the only spec that matters. Then the heavier interventions, with screening. EBOO sits here — not because it is a last resort, but because it requires bloodwork, suitability screening and a conversation about timing, which the first two do not. People who arrive wanting to start at step three usually get less out of it than people who arrive having done steps one and two for a month. That is consistently true and it has nothing to do with the therapy itself. Where Each One Is the Better Tool Light is the better answer for localised work — a specific joint, an area of skin, recovery after training, something you want to treat daily without an appointment. It is also the better answer when cost and convenience are deciding factors, because it is a one-off purchase you control. Oxygen-based work is the better answer when the question is systemic rather than local
