I don’t think there is clinical level evidence for it, but there’s this thing called Trauma Releasing Exercise which apparently some people swear by. The idea is that you do extremely taxing, high neuromuscular-recruitment static holds etc - til the point of total muscle control loss that turns into widespread trembling. I would speculate that if a big part of feeling bad is getting stuck in a state where tension becomes a problematic passive default state that is hard to get out of, that a short, hard ‘nudge’ in the form of overwhelming exertion might be enough to ‘reset’. All speculation until proven though.
What’s interesting about the origins of the technique is that the guy thought of the possibility that adults learn to suppress visible trauma reactions - uncontrolled shaking, etc - whereas children and animals wouldn’t, and for whatever reason they would also be able to return to normal more quickly. He wondered if maybe that there was a tangible benefit to the shaking itself, in that it could help perturb out of the traumatized state itself.
