decompression

Decompression is the process of decompressing—releasing or reducing pressure.

This literal meaning of decompression can be used in several contexts. Divers who’ve spent time in deep water decompress by coming up slowly. Divers and other underwater workers sometimes decompress by using a decompression chamber. The goal of decompression is to return the body to normal atmospheric pressure in order to avoid decompression sickness.

In a medical context, decompression is the process of releasing pressure in the body, such as from inside the skull, through surgery.

Decompression can also be used in a figurative way meaning the act of relaxing or unwinding. This sense of the word likens stress to pressure within the body that needs to be released. Close synonyms of the verb decompress are destress and blow off steam. 

In all senses of the word, the process of decompressing is called decompression.

Example: After a stressful day at work, my favorite form of decompression is a long bike ride.

The first records of the word decompression come from the early 1900s. Its root word, the verb compress, means “to press together.” The prefix de- means “removal” or “reversal.” So, to decompression is the removal of pressure.

For divers, decompression can be the difference between life and death. The figurative sense of decompression might not be quite as critical, but it’s still important. This kind of decompression can be done after any type of stressful situation, but it’s most often applied to what people do to switch off work mode. Sometimes, a day at work is like a day spent in deep water, with more and more pressure (stress) building up as the day goes on. Even after you finally resurface, you might still feel that pressure unless you find a way to release it. Different people decompress in different ways. For some people, their commute home is like a decompression chamber, where they can decompress by listening to music or a podcast. Other popular forms of decompression are exercise, meditation, reading, watching TV, playing video games, getting a massage, or spending time with friends. The best form of decompression is the one that works.

Here is a photo (by Tane Sinclair-Taylor) to give everyone a sense of scale of our dives. Our rebreather team is in decompression at about 15m depth, joined by one support diver. Our entire decompression after a deep dive can be 5-6 hours long. #HopeForReefs pic.twitter.com/khl0RXMcYc
