Anxiety can defined as a disorder where the physiological state of a human is characterized by somatic, cognitive, behavioral and emotional components. All these components come together and trigger feelings that are recognized as worry, fear, or apprehension. Anxiety has several symptoms and these are characterized heart palpitations, breath shortness, nausea, stomach ache, chest pain, or headache. The rate at which anxiety is occurred is different in different persons and this anxiety measurement can be performed with an anxiety scale. Anxiety scale is of different types.
Somatically, the human body prepares itself to deal with any kind of threat and as a result of this heart rate increases, there is an increase in blood pressure and one perspires excessively. In many cases paling of the skin, pupillary dilation, sweating and trembling can be noticed. Emotionally, anxiety can trigger a sense of panic and physically it may lead to chills, nausea and diarrhea. Both voluntary and involuntary behavioral patterns can be observed if the victim tries to avoid or escape from the anxiety source.
But one important point to remember is that that anxiety may not always be maladaptive or pathological and can faced as a common emotion during anger, fear, happiness and sadness.
