Look at Lee Min Ho smiling and giving off happy and warm feels despite the snowy weather. Actually, scientists have now proved that love makes you feel happy and happiness makes you feel warm all over. Here's the image map that shows how different body regions are affected by different emotions.

Scientists have been wondering about the connection between physiological changes and our emotional state. According to the study conducted at the University of Turku in Finland, regardless of someone's education or cultural background, one's emotional state directly affects his or her physical well being. The result is a map showing the "heated" areas compared to the "cold" areas depending on someone's emotional state.

In the image map, yellow shows the regions of increased sensation while blue areas represent decreased feelings. It explains how love creates a glowing and pleasant sensation, and happiness makes one feel warm all over from head to toe. By contrast, anger can literally make someone feel hot-headed, and disgust is felt in the throat and digestive system. Someone who feels a heart-wrenching loss can actually feel physical pain in the heart, while sadness makes the body feel numb and weak.

While the study explains why we feel warm and happy when we're in love, it is also important to help understanding of the opposite of happiness. According to the researchers, "Unraveling the subjective bodily sensations associated with human emotions may help us better understand mood disorders such as depression and anxiety."

Is it any wonder then that we avid drama viewers want happy endings? As we empathize with the feelings felt by our beloved characters, our bodies experience the same reactions evoked by those feelings. No wonder we want happy endings, because we want to feel love's shining glow and the head-to-toe warmth from happiness. Do you remember at the end of Heirs, the happy Kim Tan (Lee Min Ho) is walking in the snow with Eun Sang, but he is not wearing one of those heavy and awful sweaters anymore because he is happy, in love, and full of a warm glow. And we feel happy too when we see him.
