With the holidays in mind, I am sure that many of you must be very excited. But why exactly do we get so excited?Dopamine is a chemical messenger made in the brain which is released when expecting a reward. In other words, whenever experiencing an activity that is pleasurable, dopamine is released. When dopamine is released, you end up feeling more happy than you did in the moments prior. While you're opening your Christmas presents, the dopamine levels in your body increase in anticipation of getting the present inside. With that being said, enjoy the rest of your holidays!
