Muscle spasms, also known as muscle cramps, are involuntary contractions that arise suddenly and can be very painful. The antonyms of muscle spasms are muscle coordination, muscle relaxation, and muscle ease. When muscles coordinate, they work together in a synchronized fashion without any sudden jerks or twitches. Muscle relaxation is the reduction of muscle tension and stiffness, promoting flexibility, reduced pain, and improved range of motion. Muscle ease is a state of being comfortable and without any physical discomfort. To avoid muscle spasms, it is recommended to stretch regularly, stay hydrated, and maintain a healthy diet with sufficient vitamins and minerals.
