Stress – Part 5

The Alarm Stage is responsible for our “fight or flight” instincts. To meet the increased biological demands, the brain waves change, blood flow increases to the muscles, and adrenalin is released more quickly. These changes are known as the sympathetic nervous system response.

In the Resistance Stage, the body’s systems are mobilized to meet the threat of the stressor. This stage can last for a long time or a short time, depending on the intensity of the threat. The longer it continues, the more vital nutrients will be depleted in sustaining the resistance.

The body rarely gets to the exhaustion stage of GAS. But when it does, the weakest systems break down, and chronic fatigue and illness follow. The exhaustion stage seldom continues, except in cases of extreme shock or old age.
