Science of kissing: why a kiss is not just a kiss The evolutionary origins and physiology behind mouth to mouth kissing Tue, Feb 13, , Sylvia Thompson. What are the origins of kissing?

Is kissing unique to humans? Do people kiss in all cultures? Bryant Stamford, a professor at the University of Louisville, recommends the latter: "The process of being active — and that can include kissing, sex, and any other whole-body activities — that's what keeps you healthy," he told WebMD.

Got high cholesterol? Of course, you could consider the obvious route: eating healthier, whole foods, reducing your red meat intake, exercising with greater frequency, and maybe taking a doctor-prescribed medication, as recommended by the Mayo Clinic. Another potential option? Believe it or not: more kissing.

Yes, it turns out that affectionate canoodling and kissing can have a reductive effect on your blood lipids. A study published in the Western Journal of Communication followed 52 married adults for six weeks. Some were placed in an experimental group that was asked to kiss their partner more it's a tough gig, but someone's got to do it , while the control group was not given any specific instructions.

After the study was completed, those in the kissing group reported less stress, a factor that can contribute to higher cholesterol levels. What's even more impressive, however, is that blood tests showed that the kissing couples had improved their total serum cholesterol levels, in comparison to those in the non-smooching group. Of course, it goes without saying that kissing isn't an actual treatment plan for folks with high cholesterol.

But it certainly can't hurt, according to science! Need a little motivation to get your sexy time on? We have a weighty hint-hint consideration for you to ponder. Not only does kissing promote bonding, as well as reduce stress and anxiety, but it can also help you burn some major calories. Yes, you might just be able to skip a trip to the gym if you really prioritize mind over matter and, you know, put your mouth to work. So how many calories does kissing really burn? On average, kissing can burn two to three per minute, as noted by Healthline.

But a heavy duty make-out session that involves the whole body probably makes that number even higher. In fact, it's possible that a minute session could even burn up to calories.

That's equivalent to swimming laps in a pool for 20 minutes, or walking two miles in 30 minutes, according to Harvard University. So the next time you're deciding between hitting the treadmill or staying home, grab your partner and plant a long passionate one on their mouth.

You'll both be thankful, especially if you just ate a restaurant meal with more than one day's calories. Have you ever wondered why you close your eyes during an intense make-out session? It could be because you don't want to get too up close and personal with your partner's pores no one looks that good under extreme magnification.

Despite this unsightly prospect, it's more likely that you shut your eyes when kissing because your pupils have dilated, making you more sensitive to light, per Marie Claire. In this intimate instance, your pupils dilate as an autonomic nervous system response to your sudden arousal and situational enjoyment. Furthermore, pupil dilation is a sign of attraction, as noted by Healthline.

This is the body's subconscious way of allowing you to see something that's either exciting you — or worrying you — more clearly. So the next time you see your crush's pupils dilate in your face-to-face presence, it might be a sign that they think you're looking mighty good. When you kiss a potential partner, there's a whole lot of evaluation happening on a subconscious level. Beyond deciding if this person is a good kisser or not fingers crossed , you're also unknowingly deciding if they'll make a good life mate — or not.

According to Live Science , kissing is an "evolutionary screening tool" to determine if you and your sweetie can compatibly have healthy children. Additionally, your saliva and breath have chemical signals embedded within them that can clue you into whether they are the right reproductive match for you. Furthermore, the exchange of pheromones chemicals that feature important information about one's biology, as noted by Medical News Today further fuels this subconscious information swap.

Your salivary glands begin their own workout, pumping out extra spit. During a real tongue twist, about nine milliliters of your saliva finds its way into his mouth and vice versa. The gross news: That juice is teeming with as many as 1 billion bacteria. The better news: 95 percent of those are harmless.

Blood Flow If you're really into this dude, the kiss sends shock waves throughout your body that can increase blood flow to certain areas. Think stiffened nipples, fluttery stomach, tingling genitals. Adrenal Glands Sensing the hubbub, the adrenal glands unleash adrenaline. Cue a pounding heart, heavy breathing, or sweaty palms. Blame our differences not on Mars and Venus, but on evolutionary history, researchers say.

Women use kissing as pre-sex screening to determine whether their partner is healthy and sufficiently bonded to stick around for the long haul of child rearing. Men's biological imperative tells them to hit it and quit it, the better to share their DNA with more lucky ladies.

So females put a lot of emphasis on making judicious mate choices. Of course, college students aren't thinking about judicious mate choices when they grab someone cute to snog at last call. But evolutionary habits die hard, researchers say. She acknowledges that what's true for college students may not hold for older adults; but, she notes, college students are in their reproductive prime, from an evolutionary if not an emotional standpoint.

Women in the study rate kissing as more important than men do at all stages of a relationship. Men are much more likely to skip to the main event: 53 per cent said they would have sex with someone without kissing, compared with only 15 per cent of women. Men are also much more likely to have sex with someone who's a bad kisser.

Nice-looking teeth and lips figure strongly in women's decision whether to kiss someone, and their kissing partner's breath and mouth taste is important. Men, meanwhile, are more concerned with their potential partner's body shape and weight, and they say a good kiss includes their partner making moaning noises. Men may have an ulterior motive for preferring wetter kisses, Dr.
