Exploring Red Light Therapy in the Context of COVID-19

Today we are sharing insights from a case study conducted last summer (2020).

  • Introduction
  • Results
  • Conclusion


As researchers worldwide continue to study COVID-19, there is a growing interest in understanding its effects on the body, particularly the hematopoietic system and hemostasis. These systems are known to be influenced by light, especially within the visible and infrared spectrum.


A study observed COVID-19 patients with a notable accumulation of iron in their bloodstream, which was associated with an inflammatory response, indicated by increased levels of C-reactive protein and albumin.

In this context, researchers explored the use of Red and Near-Infrared Radiation (R-NIR) combined with Vitamin D, obtained through Ultraviolet B (UVB) radiation, to potentially support the body's immune response.

The study explored how light absorption might influence the stability of the iron ion bond within the heme group, potentially impacting oxygen transport. Additionally, it was noted that light absorption by cytochrome c oxidase in the R-NIR region could lead to increased electron transport, potentially enhancing mitochondrial oxygen consumption and ATP production.


The study suggests that the R-NIR region, where cytochrome c oxidase and porphyrin have absorption peaks, could be of interest for further research. The hypothesis is that light therapy might play a role in supporting the body's response to COVID-19.
