French kissing – French kissing increases resistance

French kissing (it is also called French kissing) is not only tasty, it is also healthy. It is of course healthy because of the mental side. Anyone who kisses a lot with their sweetheart feels loved and that is good for body and mind. Now the bacteria exchange that takes place during kissing also appears to be good for the system. Why don’t animals kiss and people kiss? This was discovered after kiss research. It is clear what the evolutionary necessity is for the saliva exchange that takes place during kissing: French kissing increases your resistance.

French kissing

French kissing, or French kissing, is a step in courting a sweetheart. It’s exciting and delicious. Now it also turns out to be healthy and that is due to the bacteria exchange that takes place during a heavy kissing session.

Bacteria

Bacteria are not all bad for us and the exchange of bacteria is not always disastrous for our health. On the contrary. Researchers from TNO Zeist discovered that French kissing is good for people. With French kissing, a lot of saliva is exchanged and with that saliva also bacteria. The researchers discovered that kissing causes the collection of bacteria in the saliva of the two kissers to resemble each other, which has its advantages.

Professor Short

Prof.dr.ir. Remco Kort, microbiologist and principle scientist at TNO and professor of Microbial Genomics at the VU, made the discovery after thorough kissing and saliva research. The research took place as a collaboration project between TNO and Micropia. The results of the research were incorporated into the exhibition setup of the Kiss-o-meter in Micropia. The research forms the scientific basis for the kiss meter in the world’s first microbe museum.

Kiss research

Remco Kort conducted a kissing study together with employees from Micropia and Microbiology and Systems Biology researchers from TNO Zeist. They investigated how many bacteria two kissing people exchange during a nice kiss.
Kissing actually exposes you to a huge amount of bacteria in a short period of time.

80 million microbes

To put a nice figure on it: 80 million microbes pass back and forth between the two kissing partners in 10 seconds. Some settle on the tongue, but not all those millions. They spread in the body. The study wanted to determine to what extent the oral microbiota matches the microorganisms in the mouths of partners. The oral flora of the kissing partners was mapped for this purpose.

Oral flora

The study in which 21 couples were allowed to kiss casually shows that the oral microbiota of people who have kissed each other vigorously is more similar than the oral flora of people who have only shook hands. For the similarities on the tongue, it does not matter whether the kissing partners lap at each other all day long or whether they kiss each other a few times a year. More factors play a role in similar oral flora, such as using the same toothpaste and following the same diet. Frequency does matter for similarities in saliva. The more often people kiss, the more similar the saliva becomes in terms of the collection of bacteria. The same types of bacteria do not linger in the mouth, but spread throughout the body. There are more similarities to be discovered in people who kiss.

Immune system

The mouth is a breeding ground for bacteria and that is why we initially think that kissing is not healthy. We quickly think that it is not hygienic and therefore not fresh and therefore unhealthy. The researchers actually discovered that kissing is healthy. It gives the immune systems of both kissers a huge boost. Anyone who regularly French kisses for at least ten seconds will not only come away with a pleasant feeling, but will also be healthier.

Evolutionary necessity

It is not without reason that we have adhered to the habit of kissing since time immemorial. Professor Kort’s research discovered the evolutionary necessity of saliva exchange. About 90 percent of people on earth enjoy kissing and practice this form of intimate contact where tongues play with each other and saliva passes from one to the other. It was not clear why people – it is not seen in animals – did this, but the results of Kort and his colleagues’ research provide a logical explanation.

Digestion and allergy

People who have become more similar on the inside through kissing are more resistant to similar infections and can both digest the same food better. It also has a positive effect on the development or absence of allergies. It is not at all healthy to live a very clean life. Kissing and saliva exchange brings this back into a healthy balance.

TNO

Remco Kort is one of the scientists who works at TNO. TNO is the Dutch Organization for applied scientific research. The organization addresses social issues by conducting research within the Technical Sciences expertise area. Within the expertise area Earth, Life and Social Sciences, research is conducted into earth, environment and life issues. TNO has various locations and knowledge centers at home and abroad from which the experts work. The central core house is in Zeist.

Kissing increases resistance

In addition to that important microbe exchange that is good for your resistance, there are a number of benefits to French kissing. All in all, French kissing is good for:

• your resistance
• reducing stress
• the feeling of romance, love and lust
• the stimulation of fantasy
• the physical pleasure
• the communication
• getting to know your kissing partner.
