In valentine day yesterday, a panel discussion held scientists. Self-interest issues discussed, not far from the problems of love, that is, the mystery at the heart terpaut embedded in the mouth and lips (kiss).
Experts said that, action will be followed by a smack release chemical substances-substances that can be muted stress hormones. “Chemical compound in the saliva could be a way to assess the pair,” said Wendy Hill, professor of Neuroscience expert Lafayette College during the event titled the American Association for the Advancement of Science held.
In an experiment, Hill explained, the pair heterosexual college students who are experiencing changes in the chemical compound Oxitocin degree cortisolnya and when they do kiss scenes for 15 minutes while listening to music.
Oxitocin, Hill said, affect the closeness relationship pair, while cortisol associated with stress. Chemical compound in the blood and salivary gland ago be examined before and after the kiss lasted.
Both men and women decreased after osculation cortisol degree, indicate degree stress also decreased.
For men, while osculation, increased of oksitosin level mark up for a strong partner, while the women okcitosinnya thus decreased. “Of this staggering,” said Hill.
In a pilot group that examine the effects hold hands, chemical changes also occur in this action, but not many that can be disclosed or results not far different. This experiment, Hill said, is done in the student health center at the college. He repeated the plan will be designed “in a more romantic atmosphere.”
Together with Helen Fisher of Rutgers University and Donald Lateiner from Ohio University, Hill spoke at a session entitled “The Science of Kissing.”
Fisher own records, more than 90 percent of the world do people kiss. This action belived has three components, among others, encouraged sex, romantic love, and bound with someone.
Encouragement sex encourage someone to assess and determine the pair each, while romantic love cause they focus on an individual, and being bound to someone, he said, to make someone leave this in the private long time raising a child together.
Men, he said, tend to think that smell is the initial of the sex activities or ovulation. He mentioned that men tend to prefer any smell. However, men testosterone consist chemical compound can be mixed in the saliva of women. Testosteron increase sexual encouragement for men and women.
“When you smell, in particular the brain active,” he added. Romantic love can take a long time, “If you kiss the right person.”
Lateiner, classical scientist, observation smell that sometimes appear in the Greek and Roman art, although it is widely done in addition to the smell of someone skin. Therefore, it is potentially dangerous for the life of someone if the kiss is done on the wrong people and less time doing it.
In general, the science of smell-philematology-still running. Likewise knot Hill.
