FIR Radiant Heat dangers

Hi,
My yoga studio uses this heat in their studio and I am only just starting to find out about it.
There is a lot of information saying that there are possible benefits to this heat, but the mention of long range rays is very concerning to me.
I had previously though UVA was the most damaging ray from the sun you could get (I had heard that UVB causes change of colour/ tanning which is damaging but that UVA was worse in that it was what causes wrinkles) and that this was the longer/ deeper penetrating ray.
Is there any similarity between UVA and Far Infra R R heat?
I always wear sunscreen during day time and avoid being in the sun where possible. I am worried that I may be getting damage from my yoga studio now, where I remove sunscreen.
(I take vitamin D supplements and get sun on my arms and legs just not face as I know I need vit D)
Please let me know if I could get any damage at all from the FIR Radiant Heat.
Thank-you

Hello,
Far-infrared radiant (FIR) heat is a form of naturally occurring energy that heats objects by direct light conversion (DLC). It warms only the object and does not raise the temperature of the surrounding free air.

It has nothing to do with UV rays and hence it does not cause any of its side effects. It has no long terms side effects.

It is very difficult to precisely confirm a diagnosis without examination and investigations and the answer is based on the medical information provided. For exact diagnosis, you are requested to consult your doctor. I sincerely hope that helps. Take care and please do keep me posted on how you are doing.
