That’s something to ponder! Altho, I have read tons when it comes to red light or near infared light therapy helping with immunity boosting. It may not cure coronavirus but it will help with strengthening the immune system.
Indirectly, I think near-infrared light can help people recover/ reduce the effect of infection since stronger immunity is also a product of infrared light therapy. One of the core reasons why the older populations are more prone to serious/critical states when infected is due to low immunity.
I guess that what most health practitioners all over the world is telling everybody to build a stronger immunity so if in any case the virus hits them it won’t affect them that much unlike those who have weaker immune system. And as per the comments above me, I agree. Indirectly, it helps reduce the infection in our bodies.
