When a person experiences stress, the brain responds by initiating 1400 different responses including the dumping of a variety of chemicals to our blood stream. This gives a momentary boost to do whatever needs to be done to survive. If left unchecked, however, the person can have a heart attack or stroke. Many people start drinking alcohol. They get depressed, find it difficult to sleep, experience chest pain. The body runs out of the immunity to fight diseases. So, very often, these persons die of disease such as cancer, pneumonia, etc. The stress will never be identified as the cause of the death. I call the stress the proxy killer. Some other disease always takes the blame for it.

Doctors call the body’s reaction to stress as General Adaptation Syndrome (GAS). There are three stages to GAS.

In the first stage of GAS called alarm reaction, the body releases adrenaline and a variety of other psychological mechanisms to combat the stress and to stay in control. This is called fight or flight response. The muscles tense, the heart beats faster, the breathing and perspiration increases, the eyes dilate, the stomach may clench. Believe it or not, this is done by nature to protect you in case something bad happens. Once the cause of the stress is removed, the body will go back to normal.

If the cause for the stress is not removed, GAS goes to its second stage called resistance or adaptation. This is the body’s response to long term protection. It secretes further hormones that increase blood sugar levels to sustain energy and raise blood pressure. The adrenal cortex (outer covering) produces hormones called corticosteroids for this resistance reaction. Overuse by the body's defense mechanism in this phase eventually leads to disease. If this adaptation phase continues for a prolonged period of time without periods of relaxation and rest to counterbalance the stress response, sufferers become prone to fatigue, concentration lapses, irritability and lethargy as the effort to sustain arousal slides into negative stress.

The third stage of GAS is called exhaustion. In this stage, the body has run out of its reserve of body energy and immunity. Mental, physical and emotional resources suffer heavily. The body experiences "adrenal exhaustion". The blood sugar levels decrease as the adrenals become depleted, leading to decreased stress tolerance, progressive mental and physical exhaustion, illness and collapse.
