Bio freck Posted March 17, 2012 Author Share Posted March 17, 2012 This depends on the autonomic nervous system how it is able to dilate or constrict with respect to emotions. Link to comment Share on other sites More sharing options...
HGrimston Posted June 5, 2012 Share Posted June 5, 2012 When you undergo arousal, or any kind of stressor in general, your body is releasing glucocorticoids. One of the reactions to glucocorticoids is iris dilation, because this lets your eye receive more light, and thus you see more, and can react to the situation at hand. It doesn't matter if it's a dangerous situation or not - your body reacts to glucocorticoids by preparing for a stressful event, and glucocorticoids get released when you become emotionally aroused or stressed.
