Hmmm, wasn't there a study that showed that cognitive dissonance, or more specifically proving to someone that their own two beliefs are contradictory, caused visible stress in the brain? Obviously there are caveats, "increased activity in the brain" doesn't necessarily equal pain, and cognitive dissonance is not the same as just hearing an opposing viewpoint but it can be a consequence of that.
That said I'm definitely not advocating for sheltering people from opposing viewpoints. On the contrary, cognitive dissonance is a feeling and like any other feeling it can be gotten used to, and the more people talk about stuff the less jaded they'll be when they disagree. Going out of your comfort zone and discussing stuff is healthy, echochambers are not.
