Crying is a physical way of releasing the energy from emotions that you feel. And as emotions are ‘energy in motion’, it is very important to let these feelings out so that they don’t get trapped in the body. Children innately know to do this. It is only by adults telling them not to cry that we as adults forget how calm and clear your head can be when you’ve cried all the feelings away.
Of course we then talk about the situation that lead up to these emotions to understand better what just happened. All in the name of better emotional intelligence!
