Kissing is an exciting and intimate feeling. But did you know that kissing is not just a meeting of the lips with lip. Kissing also involves a variety of facial muscles, hormones and other body movements.
Researchers from Lafayette College, Pennsylvania said, kissing will increase certain hormones in the brain. Expenditures hormones is the result of a combination of feelings of love, passion, and feeling relaxed. Holding hands, eye contact and hugging while kissing is also known to reduce levels of stress hormone, cortisol.
The key there is kissing on the lips. But when you do kiss the warm and deep, there are 34 facial muscles involved moving. Meanwhile, a simple kiss that we do only have two facial muscles alone.
Kissing also involve saliva. But according to research found men were more "wet" than women. "There is evidence that in male saliva contains testosterone which will increase the sexual drive. Therefore when kissing, men tend to produce more saliva, one of its functions to transfer testosterone to improve sexual desire of women," says Helen Fisher, an anthropologist from Rutgers University .
Beyond these scientific matters, a perfect kiss should also have a rhythm, slowly but long, light and soft, then the faster, hot and exciting.
A survey also said 66 percent of women and 59 percent of men say the first kiss will affect the quality of relationship continuity. In other words, the way you kiss could make the sticky with your lover, or otherwise, thrown away.
