I have been looking into 5G millimeter wavelength penetration of the skin and I kept reading that it is safe because not only penetrates to a depth of 1mm (maybe 2mm, it depends who you read).

I know that both Langerhans and T cells are prolific in this same layer of the skin. And these cells, when triggered, send immune signals to the whole body. (https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2950871/)

So have there been any studies on this effect? I have searched and cannot find anything. I know CD8 T Cells are effected by calcium ion channels and these channel might be opened by these EMFs triggering higher calcium entry into the T cell and stimulating an immune response.

T cell signaling is relevant to quite a few neurological disorders

So are we overlooking the fact that 5G can effect the immune system even though there is no heating?

I am open to factual critiques and maybe a study I have not seen. Specifically any studies that have measured T cell or immune changes in the epidermis upon expose to all the 5G wavelengths.
