Researchers investigating pain responses found that when women are able to view a picture of their partner, as opposed to photos of an object or a stranger, they experienced a lower perception of pain. The longer the women had been in the loving relationship, the stronger the brain activity where they sensed feelings of safety -- an area that can inhibit signals of fear and anxiety. Also, brain activity was lowered in the area responsible for a stress response.
