When a person becomes anxious, sad, scared, aroused or angry, the body immediately begins to go through changes to meet with the new situation. Of course, we needn't concentrate only on the negative emotions. Changes also occur when we are delighted, loving, excited, joyful, playful and full of laughter. We increase the amount of air we breathe by breathing faster and deeper. Our heart quickens it's pace, more blood flows through the arteries and veins, our senses become more acute, we become more alert.
Human beings are capable of a great range of many emotions and physical responses.
We can be placid like the waters of a gently flowing stream or raging like the ocean in a fierce storm. The change from placid to storming can happen in the twinkling of an eye. It's all part of being human, even necessary to being human. It is the connection between emotions and physical responses that concern us when we think about panic attacks. Recently I was watching a person whose breathing was being monitored as he was pretending to be angry with someone else.
