“Part of the whole attraction process is strongly linked to physiological arousal as a whole,” said Timothy Loving (his real name), assistant professor of human ecology at the University of Texas, Austin. “Typically, that’s going to start with things like increased heart rate, sweatiness and so on,”
When you catch sight of your beloved and your heart starts racing, that’s because of an adrenaline rush, said Dr. Reginald Ho, a cardiac electrophysiologist associate professor of medicine at Thomas Jefferson University Hospital in Philadelphia, Pennsylvania.
Fisher’s research team did brain imaging of people who said they were “madly in love” and found activity in the area of the brain that produces the neurotransmitter dopamine. Dopamine and norepinephrine are closely related.
Love also has health benefits for people who have aged beyond their reproductive years, she said. Being in love makes people feel optimistic, energetic, focused and motivated.
