Derived from the prefix 'de-' (meaning down, away, or reversing) combined with 'compress' (from Latin compressus, past participle of comprimere, meaning to press together). Initially used in physics and diving contexts regarding pressure reduction, the term evolved in the late 20th century to metaphorically describe the release of mental tension and stress.
