Explain the difference between acute and chronic stress


Acute stress. Acute stress helps us generate great strength, focus more clearly, increase our speed, and perform at a higher level when a threat is present, but for a very short time—probably little more than 30-90 seconds. Our bodies don't have the energy reserves to support maximal energy output for much longer than that. Occasionally we can use this source of immediate energy to help us when we do find ourselves, or others, in actual danger, facing potential pain or even death.

Chronic stress. If stressful situations pile up one after another, the body has no chance to recover. This state of continued sympathetic nervous system activation is called chronic stress. Instead of returning to homeostasis, the fight-or-flight response is activated for an extended time. This long-term activation of the stress-response system can disrupt nearly all body processes.
