In one animal study, researchers looked at the numerous effects that
oxytocin can produce in lab rats -- lower blood pressure, lower levels of
stress hormones, and an overall calming effect.
Altruistic behavior may also trigger the brain's reward circuitry -- the
'feel-good' chemicals like dopamine and endorphins, and perhaps even a
morphine-like chemical the body naturally produces, Fricchione explains.
"If altruistic behavior plugs into that reward circuitry, it will have the
potential to reduce the stress response. And if the altruistic behavior
continues to be rewarding, it will be reinforced."
Again, Scrooge is a good example, says Post. "He comes alive because of
his benevolent affections and emotions. What's really happening is that he's
tapping into the whole neurology, endocrinology, and immunology of
"All the great spiritual traditions and the field of positive psychology
are emphatic on this point -- that the best way to get rid of bitterness,
anger, rage, jealousy is to do unto others in a positive way," Post tells
WebMD. "It's as though you somehow have to cast out negative emotions that
are clearly associated with stress -- cast them out with the help of positive
