act of suppressing the emotion produced increased activation in the ‘sympathetic nervous system’ (SNS). The SNS is the part of our nervous system that sets off the ‘fight or flight’ response and gets us ready for action. Along with the release of stress hormones, it increases our heart rate, blood pressure and breathing in order to tackle the task at hand. If this type of activity is prolonged it takes us into a state of chronic stress. So if we suppress either positive or negative emotions this has an effect on our body similar to that that occurs when we are dealing with something stressful.
