In this Valentine's Day, a panel discussion was held scientists. Quite interesting issues to be discussed, not far from the issue of compassion, which is when the heart adrift mystery embedded in the lips and the lips (kiss).
Said experts, the kiss of action to be followed by the release of chemicals that can reduce stress hormones. "Compounds chemicals in saliva may be a way to assess the couple, "saidWendy 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 college students that experienced changes in the levels of chemicals oxytocin and cortisol when they do kiss scene for 15 minutes while listening to music. Oxytocin, said Hill, affect the relationship partner, while cortisol associated with stress. Chemical compounds in the blood and salivary glands examined and compared before and after the kiss took place. Both men and women experience a decrease in cortisol levels after the kiss, indicating stress levels also decreased. For men, when the kiss, in increased levels of oxytocin mark a strong interest on their partner, while in women oksitosinnya is decreasing. "Of course this is shocking," said Hill.
In a test group that examined the effect of holding hands, chemical changes also occur in this action , but did not have much to say or the results are not much different. This experiment, said Hill, conducted at the student health center at the college. He plans to repeat the draft "in a more romantic atmosphere." Along with Helen Fisher of Rutgers University and Donald Lateiner of 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. The sex drive to encourage someone to assess and determine their partners, while romantic love causes them to focus on an individual; and attachment to a person, he said, makes someone let this private for long periods of raising children together.
Men, he said, tend to think that kissing is the start jamming sex or copulation. He affirmed, men tend to prefer any smell. However, the chemical compounds can be readily mixed male testosterone in saliva 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, classic science scholar, observed that kiss sometimes appear in Greek and Roman art, although widely implemented in addition to the activities kiss one's skin. Therefore, potentially harmful to one's life if the kiss was carried out on the wrong person and an inconvenient time. In general, the science of kissing-philematology-still continue to run. Thus knot Hill.
