What is DOMS? What causes it and how should it be treated?

Please answer in a paragraph.

DOMS stands for Delayed Onset Muscle Soreness. It is a type of muscle soreness that occurs after a workout or physical activity. It is caused by microscopic tears in the muscle fibers due to the strain of the activity. DOMS usually occurs 12-24 hours after the activity and can last up to 72 hours. To treat DOMS, it is important to rest the affected muscle and apply ice or heat to reduce inflammation. Gentle stretching and light exercise can also help to reduce the soreness. It is important to stay hydrated and eat a balanced diet to help the body recover.
