Physical stressors produce mechanical stresses on skin, bones, ligaments, tendons, muscles and nerves that cause tissue deformation and (in extreme cases) tissue failure. Chemical stresses also produce biomechanical responses associated with metabolism and tissue repair. Physical stressors may produce pain and impair work performance.

The stress across a surface element (yellow disk) is the force that ...
Prolonged stress can disturb the immune, digestive, cardiovascular, sleep, and reproductive systems. [17] For example, it was found that: Chronic stress reduces resistance of infection and inflammation, and might even cause the immune system to attack itself. [27] Stress responses can cause atrophy of muscles and increases in blood pressure. [28]
