A strain in one's body usually refers to an injury or overexertion of muscles or tendons, causing pain and discomfort. A strain in one's mind can refer to mental stress or tension, leading to feelings of overwhelm or exhaustion. Both physical and mental strains can benefit from rest, proper care, and in some cases, professional help.
