Anxiety is a feeling of fear, apprehension and discomfort over a situation. This is actually a good and healthy feeling since the body is able to recognize something that it needs to address. This “flight or fight” response enables the body to get that much needed boost of energy to react to the specific situation. In this case, anxiety is helpful. However, if it gets intense, recurring and exaggerated, it may already be considered as an anxiety attack.
The exact cause of an anxiety attack is not fully understood, but research suggests that genetics, life experiences and brain chemistry contribute to the onset of the attack. What is known is that during the attack, a person shows signs and changes in the body.
The immediate sign of anxiety attack is increased heartbeat or palpitation. This is the most distressing among anxiety symptoms. But this is generally a good thing since the heart works harder to pump more blood to your body, especially to your legs and your arms, enabling you to have a surge of energy to respond quicker than normal to any emergency. The chest feels tight as if it refuses to expand to accommodate air the body needs. Sometimes, the feeling is like someone is pushing a pillow into your face.
The additional oxygen requirement of the body must be compensated by breathing. Thus, during an anxiety attack, you breathe faster. As your arms and legs receive more oxygen and energy, your muscles tend to get tensed, which is important when abrupt movement is needed.
