Red Light Therapy shines light on Covid-19

Could Red light Therapy become an effective treatment for Covid-19 patients?

Today we are sharing another promising case study conducted last summer.

  • Introduction
  • Results
  • Conclusion

As researchers around the world slowly start to understand how Covid-19 affects and attacks the body, many agree that it causes a systematic infection that affects the hematopoietic system and hemostasis. Those two factors are extremely dependent on light, mainly in the spectrum of visible and infrared radiation. 

As a result of this discovery, the following study was conducted, with positive results and new promising data.



Researchers identified Covid-19 patients that were accumulating an extremely harmful amount of iron in their bloodstream. This accumulation of iron was inducing an intense inflammatory process in the body with a consequent increase in C-reactive protein and albumin.

As a treatment, they used Red and near-infrared radiation (R-NIR) and vitamin D using ultraviolet B (UVB) radiation, to increase the production of adenosine triphosphate (ATP).

These two compounds have the primary role of activating the defense mechanisms of the immune system, enabling greater resistance of the individual against the attack of the virus. 

But how does it work?

Firstly, after the photon absorption, there is an increase in the stability of the iron ion bond with the center of the pyrrole ring, preventing the losses of heme function oxygen transport (HbO2). 

Secondly, the light is also absorbed by cytochrome c oxidase in the R-NIR region, with a consequent increase in electron transport. This increase regulates enzyme activity and results in a significant increase of oxygen rate consumption by mitochondria, increasing ATP production.

Above all, the most favorable range of optical radiation is between the R-NIR region, in which cytochrome c oxidase and porphyrin present absorption peaks centered at Red Light and HbO2 with absorption peak centered at Near Infrared Light. 

In conclusion, based on the process described above, the researcher’s hypothesis is that light could reduce the lethality of COVID-19.
