Sorry but you missed the point...the definitions are NOT from the Dominican dictionary, but from the Royal Academy of the Spanish Language in Madrid...and they do not even mention it is a regionalism (which they do when appropriate)...the definitions starting with "Med" are MEDICAL definitions...so, obviously, Dominicans did NOT invent the word or notion of "pasmar(se)". In all likelihood the notion came from the same place from where the word came: Spain. In fact, considering that Southern Spain (and even Madrid) can get EXTREMELY HOT in summer time (over 40C/100F easily) it would not be surprising they developed a concern about the effect of sudden change of temperature, especially from hot to cold....
