What type of stress can be created from physical exertion, like lifting heavy objects?

Explanation:
Physical exertion places a direct load on the body, creating physical stress. This is the mechanical strain on muscles, bones, and connective tissues as you lift or carry heavy objects. The body's reactions to that load—like a faster heart rate or heavier breathing—are physiological responses, not the type of stress being described. Environmental stress comes from external conditions such as heat or noise, and psychological stress comes from mental or emotional factors. So the stress produced by lifting heavy objects is best described as physical stress.
