14 Things The Dirty Truth About kissing

Scent is used by the majority of animals to identify potential mates. According to the BBC, animals emit potent, odorous compounds known as pheromones that provide potential suitors with information about their general health.The evolution of kissing, a behavior “that places individuals in close proximity to each other in order to smell, taste, and assess other features that may contribute to making mate assessments,” may have also been influenced by scent, according to a study published in Evolutionary Psychology.

Researchers wanted to know how much breath and taste during a kiss affect a person’s assessment of a possible partner because a person’s breath can indicate signs of underlying health issues. They discovered that kissing was a crucial factor in determining whether or not women will have sex with males after polling 1,041 college students. Additionally, they discovered that a person’s breath quality was a significant consideration, with foul breath being a deal-breaker. In addition to the fact that foul breath is, well, disgusting, it also raises the possibility that the offender may have faulty genes that could harm their future progeny.

4. Millions of microorganisms enter your body by kissing.

Here’s a shocking image: a study that was published in the journal Microbiome found that a 10-second kiss can transfer up to 80 million bacteria from one person’s mouth to the other.After examining the kissing habits and bacterial levels in the bodies of 21 couples, researchers in the Netherlands came to the startling conclusion. Initially, the researchers conducted a survey to determine the frequency of kisses between the participants. They next compared the amounts of bacteria in their mouths after swabbing them. The findings showed that the amount of bacteria in the mouths of the couples increased with the frequency of their passionate kisses.

The researchers then gave one member of each couple the duty of consuming a probiotic shake that contained particular trackable bacteria in order to examine these findings further. The scientists assessed the amount of bacteria in the mouths of the couples after they had kissed for ten seconds. The lead author of the study, Remco Kort, told Science Daily, “We wanted to find out how much partners share their oral microbiota — and it turns out, the more a couple kisses, the more similar they are.”
