Countering Chronic Asthma Inflammation With Red Light Therapy?

Another week with huge updates!

We consider a study on pulmonary inflammation in animals below. And we include new content such as our Science Tool that should lower the information overwhelm at this website, and there's an enormous sale going on right now with some companies, plus polls, and more.

Red Light Therapy For Pulmonary Inflammation In Chronic Asthma - Animal Study

So this new study just came out (April 2026) on using red light therapy for chronic inflammation in asthma. You can read the full text HERE.

The topic is interesting because respiratory conditions aren't a main avenue of research in the space. We see a lot more high-quality research on topics such as osteoarthritis, fibromyalgia, skin health and beauty, and so forth.

Arguably, in humans, the respiratory system is also harder to treat as much of it is located deep inside the torso. Although that's not necessarily limiting as people such as Tom Kerber have stated in interviews they've treated their COVID very well with red light therapy.

But I digress. Let's consider the current April 2026 study. Here's what researchers conclude:

"These findings demonstrate that [red light] therapy, particularly at intermediate radiant energy doses, effectively modulates immune responses, attenuates airway remodelling, and reduces chronic pulmonary inflammation in experimental asthma."

And, yes, as the study already mentions, there's different effects at different doses. Intermediate doses work best here, in the animals, but keep in mind, it's very easy to penetrate deeply into a rat or mouse becuase they've got such small bodyweights and dimensions.

For humans that dynamic is very different, as our diameter is a lot bigger. So, reaching internal organs such as the lungs, or even liver, is harder for us.

Here's the study setup described by the researchers:

"Chronic allergic pulmonary inflammation was established through subcutaneous sensitization with [ovalbumin] followed by repeated orotracheal challenges over 5 weeks. After each challenge, animals were treated with a 660 nm continuous-wave diode laser at irradiation times of 10, 30, 50, and 75 s, corresponding to radiant energies of 1, 3, 5, and 7.5 J, respectively. Twenty-four hours after the final challenge, pulmonary inflammation was assessed by cellular analysis of bronchoalveolar lavage fluid, cytokine quantification, histomorphometric evaluation of airway remodelling, and immunophenotyping of regulatory T cell populations."

So, different doses of 1, 3, 5 and 7.5 J were used here, at the 660 nm wavelength. The compound called "ovalbumin" (OVA) is used to provoke an asthmatic reaction in the mice. Then, 24 hours after the light therapy concludes with 660 nm, and different doses for different mice, the inflammatory results are measured.

The provocations with OVA and light therapy treatments lasted for several weeks, by the way. That way the exposure and buildup of asthma is more realistic in the study. See that display here:

On the treatment area, the researchers state:

"irradiation was applied to three specific regions: below the trachea and over each lung lobe."

Basically, that's both lungs and the airways going there. So that's quite helpful for translating this data into us humans - you could also treat these areas if you're affected! Likely you'll have to use more NIR for deeper penetration though.

The moral of the story? More evidence is showing benefits of light therapy for different lung conditions. Very very soon we'll come out with some articles on different topics here. The red light therapy course episode on COVID will also be released in the near future, where I (Bart) will dig deeper into light therapy for different viral infections.
