decompression

/ˌdiːkəmˈprɛʃən/

Definition

The process of reducing the pressure surrounding a person or object, particularly the gradual release of atmospheric or water pressure to prevent physical harm.

Etymology

The word is formed from the Latin prefix 'de-' (down, away) combined with 'compression,' which derives from the Latin 'compressare' (to press together). It entered English in the 19th century to describe the reversal of applied physical pressure.
