Umuhimu na Utamu wa Busu

Kumbe busu si busu tu, bali inakuambia mengi kuhusu mpenzi wako! Wanasayansi wamechunguza busu na ina maana gani kwa binadamu.

Nimekuwa nikijadiliana na marafiki hii suala. Wengine wanasema kuwa ukimpiga busu mtu halafu unasikia kama umeme unapita mwilini basi huyo anafaa kuoa/au kuolewa naye.

Wengine wankubali kuwa ukimbusu mtu na husikii raha hata kidogo basi hakufai. Wengine wanasema kuwa ufundi wa kupiga busu si kitu, muhimu ni wewe unavyojisikia baada ya busu.

Hebu someni wanasayansi wanavyosema halafu karibuni mtoe maoni yenu.

Pucker up: Scientists Study Kissing

CHICAGO, Illinois (CNN) -- When your lips gently brush against the mouth of your beloved this Valentine's Day, it may feel magically romantic, or sloppily slobbery, or blissfully gentle, or perhaps too rough and toothy.

The science of kissing even has a name: philematology. Researchers are investigating the mechanisms involved.

Regardless, the practice of kissing is nearly universal. It is practiced in at least 90 percent of cultures among sexual or romantic partners, experts say. Now, scientists are investigating the biological factors underlying that ubiquitous expression of love.

The science of kissing even has a name: philematology. Research on the subject was presented at the annual meeting of the American Academy for the Advancement of Science in Chicago on Friday.

"Kissing is not just kissing. It is a major escalation or de-escalation point in a powerful process of mate choice," said Helen Fisher, professor at Rutgers University and author of the book "Why Him, Why Her: Finding Real Love by Understanding Your Personality Type."

Research led by Wendy Hill, professor of neuroscience at Lafayette College, looked at how kissing affects the hormones oxytocin, related to social bonding, and cortisol, a measure of stress levels.

The first experiment, which took place in a student health center, looked at college students age 18 to 22, and examined hormone levels in 15 heterosexual couples. In the control group, participants held hands and talked with their partner while music played. In the experimental group, participants were told to open-mouth kiss their partner for the length of the music -- 16 minutes.

The results showed that oxytocin levels in the women decreased after the session, but increased in the men. Levels of cortisol decreased for everyone.

A second experiment in a more romantic setting -- a secluded room with jazz music, flowers and electric candles -- looked at nine heterosexual couples and three lesbian couples.

Researchers found that the longer the relationship of a couple, the more the cortisol levels declined in those people. The heterosexual women, moreover, said they felt greater intimacy with their partners than the heterosexual men or the homosexual women did, while all groups expressed equal satisfaction in kissing their partners.

A person receives information about the person he or she is smooching by locking lips, Fisher said. A kiss transmits smells, tastes, sound and tactile signals that all affect how the individuals perceive each other and, ultimately, whether they will want to kiss again.

Kissing "can really either escalate a relationship or really kill it," Fisher said.

Women tend to be attracted to male partners with a different immune system makeup from their own, Fisher said. They subconsciously detect information about a partner's immune system through smell, a sense involved in kissing, she said.

One study showed that more than 50 percent of men and women reported that after feeling attracted to another person initially, the attraction ended after the first kiss, Fisher said.

We feel such sensitivity to kissing partially because of the way our brain is structured, Fisher said. The somatosensory cortex, which extends from one side of the brain to the other, has a large portion devoted to picking up signals from the lips, tongue, nose and cheek areas around the mouth.

"You can really get poked in the back and not feel it very much, but just a feather around your lips and you really do feel it," she said.

As for the origins of kissing, one theory is that kissing evolved as an extension of the way mothers used to feed their children. Early humans, who lacked jars of manufactured baby food, probably chewed up food and directly transferred it from their mouths to the babies', said Gordon Gallup Jr., professor of psychology at the University of Albany, who did not present at this panel.

Looking at a sample of more than 1,000 college students, Gallup and colleagues found that women also tend to emphasize kissing more than men, and are much more likely to insist on kissing before a sexual encounter.

hao wazungu wameshaendelea sasa wapo katika starehe. sisi nchi masikini haya ya busu sasa si wakati wake. tuumize kichwa jinsi gani ya kuondokana na umasikini maradhi na ujinga. hatuna teknolojia waka miundombinu ya kisasa. tuna matatizo ya umeme, afya na ustawi wa jamii yetu.

tuache kuiga kila kitu hao wapo mbali sisi tufanye ya msingi kwanza starehe baadae

Yap! Nilijua nataka kumwoa nani kupitia njia ya busu. Nilisikia huo umeme kwenye busu la kwanza. Na mengine yakawa mazuri zaidi. Asante kwa mada.
