Definition of decompression

decompressionnoun

/ˌdiːkəmˈpreʃn//ˌdiːkəmˈpreʃn/

The word "decompression" originates from the Latin words "de-" meaning "down" or "away from", "compressio" meaning "a squeezing together", and the suffix "-ion" indicating a process or action. In medical and scientific contexts, decompression refers to the reversal of compression, or the release of pressure or tension that has been built up. In the early 19th century, the term "decompression" was first used in the medical field to describe the process of gradually releasing pressure on the body after a sudden change in ambient pressure, such as during scuba diving or altitude changes. This process helps to alleviate symptoms such as pain, swelling, and breathing difficulties associated with rapid changes in pressure. Over time, the term "decompression" expanded to other fields, including geology, psychology, and technology, where it refers to the release or relief of built-up pressure, tension, or stress.
