Some of the common antonyms of unstrain are "tense," "stressed," "anxious," "worried," and "uptight." When a person is experiencing tension, their muscles are usually contracted, and their mind is agitated. They may feel overwhelmed or pressured, leading to physical and mental unease.

By consciously choosing to relax and let go of tension, one can achieve an unstrained state and reap its benefits.
