Everything – every phenomenon is explainable, but at some level (levels of explanations differ), some people do it skin-deep, the others essentially.
I can explain it my way, but I can’t vouch for its 100% correctness and for the level of explanation you’re asking for, because I’m not concentrated on this subject presently…
Briefly we can say that mentioned phenomenon belongs to adaptive mechanisms of living organisms, at least I think so, but what was the reason for formation of adaptive mechanisms within any kind of living organism generally, I don’t know. I know that mentioned adaptive mechanism itself frequently becomes stronger (more flexible) by training of it (I mean that adaptive capabilities can be increased and there are some techniques for that – e.g. we know that persons who are trained physically endure stress easier than untrained ones), also for forming of adaptation to some irritation (internal or external stimulant) the obligatory existence of latter (of irritation) is necessary. After several repetitions irritation looses its sharpness (strength) as irritant. Maybe because the answer from the organism at first was maximal mobilization (as in any case of self preservation), maybe because of inhibition, which becomes stronger gradually as organism recognizes the same irritation as not so destructive (as not incompatible) and that makes mentioned irritation habitual, usual, against which it has defending mechanism (let’s call this defending mechanism - “mechanism of quick rehabilitation”)..
Maybe my answer is trivial but that’s all I can do briefly…
