Prove where is the flaw first. A small or old study is not necessarily flawed. The burden of proving they are flawed falls on you. And no, I care less that they have not been replicated because the community lacks interest. Nobody said the effect is miraculous or similar, to compete with modern medical applications, but certainly they are cheap methods that complement with other general wellness effects of spas.

The burden of proof is on the person making claims that goes against the various world organizations that claim otherwise. I agree the current models that deal with exposure are probably not accurate but again nobody has proven the beneficial claims you have stated. I tend to believe in the markets being efficient in the long run, if these spas were beneficial surely someone would have captured the data after multiple decades.

What are the various world organisations you are talking about? Because the German ones (among others) certainly have not found it harmful and have not banned it.

I told you many times, unfortunately, no one will do studies on these things anymore because there is no money it and it cannot be patented. That spas generally are beneficial, though, for general wellbeing and especially if combined with known thermal stimuli (such as sauna) is well known and there are several Finnish studies to prove it.

Last but not least, I have come across to many Americans who are generally doutbful of the medical indication of spas because there is little to no tradition overseas.

No world organization accepts radiation hormesis. Full stop. I am glad you find benefit and I am not suggesting it’s dangerous but I am also not accepting that it is beneficial.

This is not an American vs European thing please don’t make it. I am simply saying no governing body has accepted it beyond a study. Your view of the world is skewed if you think studies are not happening.

People have been questioning LNT, which is the accepted policy by most of the world including Europe. There is nuance and suggestive evidence that low dose is ok, after all humans evolved with background radiation. What is unclear is how beneficial it is and at what doses it becomes harmful. There is no clear study that shows benefit hence LNT being the adopted approach.
