> Has either not been proved to work

There's an awful lot of stuff that works, that nobody has run a large enough controlled study to prove it works. The organizations which fund medical research have specific priorities that exclude an awful lot. And a lot of things are just inherently difficult to objectively measure or control. There's no blood test for chronic muscle tension, for example.

So unfortunately, by restricting yourself to things that have been proven to work, you are possibly eliminating a lot of things that work.

But of course, trying to figure out, on your own, which stuff actually does work despite not being proven, is a long hard frustrating slog that tends to involve a lot of personal trial and error. Exactly what GP said:
