| STRESS RESPONSE |
| Slide 2 |
| STRESS x 2 |
| Acute Stress (Eustress) | ||
| alarm reaction | ||
| recovery follows quickly | ||
| may save your life | ||
| Chronic Stress (Distress) | ||
| constant/repeated stress | ||
| no recovery | ||
| impairs immune response/general health | ||
| Stages of Stress Response |
| 1. Behavioral | |
| -ascertain stimuli--visual, tactile, olfactory | |
| Stages cont. |
| 2. Autonomic | |
| -EPI release (adrenaline) | |
| -increase responses | |
| -inhibit unnecessary functions |
| Stages Cont. |
| 4. Endocrine | |
| - Aldosterone release | |
| *water retention for increase BP | |
| - Cortisol release | |
| *glucose production | |
| *protein catabolism | |
| *increase vessel sensitivity | |
| *reinforce autonomic response | |
| *decrease inflammation response | |
| Stages cont. |
| 5. Exhaustion | |||
| Body is at depleted state | |||
| Must rest in order to recover | |||
| If stress continues without recovery or exhaustion = | |||
| illness | |||
| perpetuation of illness | |||
| death | |||
| Slide 8 |
| What systems are working? |
| H-P-A-A | ||
| Hypothalamic-Pituitary Adrenal Axis | ||
| Stimulates release of hormones from adrenal cortex (medulla for nervous system rxn) | ||
| Secondary organs stimulated | ||
| Thyroid-increase metabolism | ||
| Liver-increase triglyceride catabolism | ||
| ***mobilize energy stores | ||
| Stress Paradox |
| stress can be the thing that pushes the body into overt disease | |
| stress resets homeostasis in body and must recover or exhaust to return to original homeostatic levels | |
| added stress of disease perpetuates the illness by further weakening the immune system |
