科学家发现接吻让人愉快源于荷尔蒙的分泌

The reason that kissing feels so pleasurable is that it sparks a surge of hormones in our brains, according to new research.心理学空间Q ?!x*P nHE6nv

l4k?Yu|:F5W0Couples who share a passionate kiss this Valentine's Day will enjoy sensations of relaxation and excitement because of a complex series of chemical processes, as well as their love for their partners.

The study showed that women need more than just a kiss to experience the same chemical high as men - with additional features such as a romantic atmosphere of dimmed lights and mood music also required.

Wendy Hill, professor of psychology at Lafayette College, Pennsylvania began the research to find out why the mundane physical activity of rubbing lips can elicit such a gratifying emotional response.

|%v;d |5h"N0They found that kissing reduced the levels of cortisol, a stress hormone, in both sexes. But levels of oxytocin, a hormone linked to social bonding that they expected to be boosted by kissing, only rose among the men.

It is not clear how kissing provokes such hormonal reactions, but some scientists believe they are triggered by the exchange of pheromones – chemicals our bodies release to attract sexual partners – in the saliva.心理学空间7Z{;O+k9\/@"f5x

Rn`\"C%_S v0This interaction may also have health benefits. Helen Fisher of Rutgers University, New Jersey, said: "If you share your germs with somebody, you're boosting your internal defence system."心理学空间 YZI ez~5y

-q {+JZ/o"j0This is not the first research to analyse the physical effects of kissing. In 2007 British scientists measured the brain and heart activity sparked by passionate kissing, but found it was less intense that the stimulation produced by eating chocolate.

Romantic love has also been shown to have a close link to neurological activity, with scans showing that it has similar effect to cocaine on our brains.心理学空间$M.N#Ep6~

研究表明女性要达到和男性同样高的化学反应,一个吻是不够的--还需要例如昏暗夜里一个浪漫的气氛和曼妙音乐.

他们发现接吻在两性中都会产生皮质醇--一种压力荷尔蒙.但是催产素,这种和社会结合密不可分的荷尔蒙,只有男性在接吻时才会产生.

科学家在更亲密的环境中重复试验,来验证当初在大学健康中心测试得出的不浪漫的环境会阻碍女性荷尔蒙分泌的结论是否成立.
