Mapping Emotions On The Body: Love Makes Us Warm All Over

When a team of scientists in Finland asked people to map out where they felt different emotions on their bodies, they found that the results were surprisingly consistent, even across cultures.
People reported that happiness and love sparked activity across nearly the entire body, while depression had the opposite effect: It dampened feelings in the arms, legs and head. Danger and fear triggered strong sensations in the chest area, the volunteers said. And anger was one of the few emotions that activated the arms.

The team still doesn't know how these self-reported sensations match with the physiological responses that occur with emotion.

But previous studies have found marked changes in bodily sensations in mood disorders, Nummenmaa says. "For instance, with depression sometimes people have pain in their chest."

And there's even some evidence that when you change your own body language — like your posture or stance — you can alter your mind.
