Scientific Research About French Kisses

Scientific Research in the Netherlands got 21 couples visiting a zoo in the Netherlands to participate in a study on French kisses. Saliva is collected before and after a timed ten-second French kiss.

What is interesting is that the bacteria in the saliva of couples are more similar than those of two strangers.

“Apparently, being with somebody for an extended amount of time and having a relationship leads to a similar collection of bacteria on the tongue.” – Professor Remco Kort, lead researcher, Netherlands Organisation for Applied Scientific Research.

To find see how similar the shared bacteria were, the researchers did one more test. One person in the couple drank a probiotic yogurt drink containing bacteria called Lactobacillus and Bifidobacteria and waited a bit and the couple shared 10-second, French kisses. Then they took a sample of the bacteria in the mouth of the partner who hadn’t drunk the yogurt. What the research found was that the amount of bacteria transferred to the other partner was on average full of 80 million healthy bacteria!

Quantity and Quality of French Kisses Make a Difference

The research team also found out through questionnaires that the more often a couple kisses, the more bacteria they share. A dry, prudent kiss only transfers 1,000 bacteria and a French kiss will give millions of bacteria! The study found that ten-second French kisses give 80 million healthy bacteria

Even though bacteria in the saliva changed quickly after a kiss, the bug populations on the tongue remained more stable.

“French kissing is a great example of exposure to a gigantic number of bacteria in a short time. While 80 million bacteria being transferred in just one kiss sounds scary, it is probably a good thing, acting as a form of immunization and building resistance from exposure to different microorganisms.” says Professor Remco Kort.

“If you look at it from this point of view, kissing is very healthy,” added Prof Kort.
