The word "unwound" is often used to describe something that has been set free from tension or constraint. Its antonyms, on the other hand, refer to the opposite state where tension or constraint is introduced or maintained. These antonyms include words like "wound," "tense," "strict," "inflexible," and "rigid." Each of these words represents a state of being that opposes the freedom and relaxation associated with being "unwound." Whether it's a tightly wound-up spring or a strict set of rules, the antonyms underline the importance of maintaining control and discipline, even if it comes at the cost of relaxation and freedom.
