The crossword solution for the term 'Loses Tension' is SAGS, which is an acronym for 'Stress-Associated Gas Syndrome'. This syndrome is a type of physical stress that occurs when a person experiences a sudden decrease in pressure, such as when they are underwater or in a high-altitude environment. It is caused by the body's inability to adjust to the sudden change in pressure, resulting in a decrease in oxygen levels and an increase in carbon dioxide levels. This can lead to fatigue, dizziness, and other symptoms.
