Secret Behind The kiss

On the day of Valentine, a panel discussion held by the scientists. Quite interesting problems discussed, not far from the question of compassion, which is the mystery at the heart adrift embedded in the mouth and lips (kiss). The word experts, the action of a kiss will be followed by the release of chemicals that can reduce stress hormones. "The chemicals in saliva can be a way to assess a partner," said Wendy Hill, professor of Neuroscience from Lafayette College during the event titled the American Association for the Advancement of Science took place. In an experiment, Hill explained, the heterosexual couples who are students college it undergoes a chemical change in levels of oxytocin and kortisolnya when they do the kissing scene for 15 minutes while listening to music. Oxytocin, said Hill, affecting the closeness of the couple's relationship, while cortisol associated with stress. Chemical compounds in the blood and salivary glands examined and compared before and after the kiss lasted. Both men and women have decreased levels of cortisol after the kiss, indicating levels of stress also decreased. For men, when a kiss, oxytocin levels menaiknya marks a strong interest on their partner, while in women oksitosinnya is decreasing."Sure is shocking," said Hill. In a test group that examined the effects of hand-holding, chemical changes also occur in this action, but not much can be disclosed or the results are not much different. This experiment, says Hill, performed at the student health center at the college is. He plans to repeat it with the draft "in a more romantic atmosphere." Together with Helen Fisher of Rutgers University and Donald Lateiner from Ohio University, Hill spoke at a session titled "The Science of Kissing." Fisher himself noted, more than 90 percent of the world do kiss. This action is believed to have three components, among others, sex drive, romantic love and attachment to someone. sex drive is encouraging someone to evaluate and determine each partner, while romantic love causes them to focus on an individual, and attachment to someone, he says, get someone to let this person in a long time raising a child together.Men, he says, tend to think that the kiss was the beginning nge -sex or copulation. He stressed, men tend to prefer any kiss. Even so, the chemical can be readily mixed male testosterone in the saliva of women.Testosterone increases sex drive for men and women. "When you kiss, certain parts of the brain active," he added. Romantic love can last a long time, "If you kiss the right person." Lateiner, classical science scholar, observed that the kiss sometimes appear in Greek and Roman art, although widely performed in addition to activities of kissing one's skin. Therefore, potentially dangerous to one's life if the kiss was performed on the wrong person and an awkward time. In general, the science of kissing-philematology-still continue to run. Similarly node Hill.
