According to an article published in Science Magazine, researchers say that kissing each other's lips may lead to oral diseases and acne in the mouth. According to research, throughout history, people kissed each other in a friendly and family manner, and this was a common behavior depending on the time and geographical location. But romantic, gender, and sex-based kissing was unexpectable as a very global and universal lexicon.

According to research and evidence from ancient Mesopotamia, people kissed each other 4500 years ago and this existed as a culture, and even more than expected, this has become a global subject.

 Scientists have found that kissing existed in Mesopotamian societies and is still ignored, but recorded in writings dating back to 2500 BC.

According to an article published in Science Magazine, researchers say that kissing each other's lips may lead to oral diseases and acne in the mouth. According to research, throughout history, people kissed each other in a friendly and family manner, and this was a common behavior depending on the time and geographical location. But romantic, gender, and sex-based kissing was unexpectable as a very global and universal lexicon.

According to the evidence obtained, however, kissing was an “unusual romantic approach” in many cultures and was not as localized as previous research had predicted.

That is, according to previous theses and statements, the oldest kissing began in India, 1500 years ago. However, Mesopotamian writings and inscriptions reverse all predictions and prove that kissing has always existed between couples (men and women), but when an unmarried person fell in love, kissing was considered part of their love.

"In ancient Mesopotamia, present-day Iraq, and Syria, people wrote on clay tablets with cuneiform writing. Those tablets arrived thousands of years later and kissed each other," says Dr. Trolez Punk Arbol, an expert on Mesopotamian medical history at the University of Copenhagen, "As a relationship between friends and family, there has always been a romantic approach in the past and it has been accepted."

"That's why kissing shouldn't be seen as a tradition just because it appeared in one area and spread from there. It existed thousands of years ago in many ancient cultures," Dr. Arbol said.

 Some researchers say that kissing causes acne, or in other words, causes a bacterial pus called HSV-1, and kissing may play a role in the transmission of the virus.

Dr. Arbol said, "In some Mesopotamian writings, some symptoms of the virus (HSV-1) have been seen and they describe a similar disease."

On the other hand, researchers say the texts were influenced by different dialects, eras, cultures, and religions, so they cannot be read as they appear.
