““Anxiety is a fact of life! Everyone experiences it. It began in our cave-dweller days as a fight-or-flight response . Think of it this way: If you were walking through the woods and you ran into a bear, it would be normal for your body to activate the fight-or-flight response. Your heart would race, your muscles would tense up, your pupils would dilate, you would breathe more rapidly. The same thing would happen today if you were walking down the street and ran into a mugger. There is a simple, scientific explanation of this response: Your mind and body are preparing to protect you—whether you can feel it happening or not. Let us briefly examine this process. Your nervous system is divided into two basic parts: The voluntary nervous system controls actions that require thought, such as using the different parts of your body to drive a car; the autonomic nervous system , among its many functions, suspends all nonessential activity of the body and increases the physiological activity needed to confront the situation—either by fighting or by fleeing the external threat. Here is what it is responsible for: -increase muscle tension -accelerated heartbeat -rapid breathing -constriction of peripheral blood vessels (this is what causes cold hands) -dilation of the pupils -suspension of the digestive process -dry mouth -a voiding of bladder and bowels In addition, the fight-or-flight response causes a marked increase in the flow of adrenaline through the bloodstream and therefore added strength.””
