All stress is not the same. Some is good. Some is bad. But stress is always with us in one form or another. There’s no escaping it.

Acute stress - also known as fight-or-flight response, is an anxiety disorder. It occurs when we experience either a real or perceived threat to us. The perceived threat can be physical in nature, such as a speeding car 100 feet away bearing down on us or a black bear 100 yards away from our camping tent. Or the threat can be emotional as a mother might feel as she’s waiting for the hospital to call regarding the fate of her husband or child that is lying on a hospital operating table.

The theory of acute stress response has been around since the 1920’s. When this response occurs, the body goes through a host of changes. The blood vessels narrow causing blood to drain away from the skin, hence the expression “he was white as a ghost” to describe someone who has just experienced a frightening event. The drained blood, and oxygen, flows into the muscles, lungs, and large muscles - strengthening them all. The heart rate increases enabling blood to be pumped to the various body organs faster. And the pupils of the eye becomes dilated allowing for sharper vision.

In addition to the above symptoms, the adrenal glands secrete the “stress hormone” cortisol which floods through the body. Cortisol has an immediate and dramatic effect on the body. Reflexes are heightened, immunity is increased, sensitivity to pain is decreased, and the body is suddenly filled with energy and ready to run or fight.

According to traumatic stress treatment centres, prime candidates for acute stress are soldiers returning from war. Many of the troops coming home from Iraq have experienced high levels of acute stress. Many people in the medical field, such as doctors and nurses, experience this as well.

Acute stress disorder is something a bit more serious. It is something that develops after the initial traumatic event that may have caused acute stress in the person. It’s triggered by the person merely remembering the event. Only a licensed therapist or psychologist can diagnose acute stress disorder, but some symptoms are:

1) Trouble focusing - the person may have difficulty concentrating or maintaining a train of thought and may appear as though he’s in a stupor or fog.

2) Disengagement and a diminishing of emotional responsiveness - the person may seem to be aloof emotionally, almost as if they’ve separated themselves from their feelings in order to avoid further pain.

3) Recurring Short term memory loss - the individual may enter a room to retrieve something and suddenly can’t recall what it was she needed. Or, she may start to ask you an important question, but can’t remember what she wanted to ask.

In order for symptoms to be classified as acute stress disorder, they must take place within 1 month subsequent to the initial traumatic event. This disorder is very intimately associated with PTSD or post traumatic stress disorder. PTSD is essentially a longer lasting type of acute stress disorder.

Generally stress is considered bad for us. And usually it is. But acute stress or short term stress is a centuries old survival mechanism that helps us to cope with wrenching events in our lives.
