When we feel anxious a chain of automatic events occurs in our bodies which prepares us for action. This reaction is called the Flight or Fight response i.e. either to run away from the danger or to stand and fight it.
The reaction consists of the brain sending a message to pump a hormone called adrenalin into the blood stream and muscles of the arms and legs. The heart beats faster as it works harder to pump the blood and adrenalin around the body and this can cause palpitations and increased blood pressure. We breathe more quickly as the lungs are having to work harder, we generate more heat so our skin looks red and we sweat more to cool down. Our muscles become more tense causing aching muscles and tiredness, our mouth becomes dry and there may be difficulty in swallowing. Our digestion slows down as the blood is diverted away from the stomach to the large muscles and this may cause sickness, indigestion, butterflies. The body needs to be as light as possible so it gets rid of waste products causing the need to go to the toilet. The release of adrenaline and increased blood pressure causes headaches and dizziness.
