The word **减压** (jiǎn yā) is a modern Chinese compound formed by combining the character **减** (jiǎn), meaning "to reduce" or "to decrease," with the character **压** (yā), meaning "pressure." It is a straightforward semantic combination where the first character modifies the second, creating the literal meaning "to reduce pressure." This term functions as both a verb ("to decompress" or "to relieve pressure") and a noun ("pressure relief"), and it is widely used in both technical contexts (e.g., engineering, physics) and, more commonly today, in psychological and social contexts to describe the act of alleviating mental stress or lifestyle pressure.
