Taking regular breaks from your work and doing stretching exercises may reduce the risk of repetitive motion injuries.

True
False

Correct Answer

A. True

Explanation

Regular breaks from work and stretching exercises can help reduce the risk of repetitive motion injuries. Repetitive motion injuries occur when the same movements are repeated frequently, leading to strain and damage to muscles, tendons, and joints. Taking breaks allows the body to rest and recover, preventing excessive strain. Stretching exercises help improve flexibility, increase blood flow to the muscles, and reduce muscle tension, which can further decrease the risk of injuries. Therefore, it is true that taking regular breaks and doing stretching exercises can help reduce the risk of repetitive motion injuries.
