5 Interesting Facts About Smooching for International Kissing Day
Because July 6 is the celebration of the kiss

July 6 is International Kissing Day, which was founded in 2006 to celebrate kissing and the important role it plays in our relationships. And why shouldn’t kissing have its own special day? Whether it’s a peck on the cheek or a passionate tongue dance, kissing is extremely enjoyable — if it leads to sex or is just done on its own. However, there’s a lot more to kissing than you may realize. The following are five interesting facts about kissing that you may not know.
Tongued and Toned
When you kiss your partner, you’re not only getting pleasure, you’re getting a workout. That’s because kissing uses 146 muscles — 34 facial and 112 postural muscles. The orbicularis oris, which is the muscle around the mouth, does the most work during a kissing session, thus becoming even stronger for the next tongue lashing.
Lengthy Lip Locks
Some people have really taken advantage of the strong mouth muscles they build up when kissing. In 1926, the stars of Don Juan, John Barrymore and Mary Astor, used their mouth muscles to kiss 127 times throughout the movie. In real life, it wasn’t a series of kisses that got attention for Thai couple Ekkachai and Laksana Tiranarat, but rather one long kiss. How long? The Tiranarats set the Guinness World Record for the longest kiss after locking lips for 58 hours, 35 minutes, and 58 seconds.
Most of us aren’t going to use our face muscles nearly this much in one kissing session, but we will use them quite a bit. In fact, people tend to kiss for 336 hours on average in their lifetime, though they don’t come close to breaking the Tiranarats’ single kiss record. Chances are, we may not even kiss as long as the lengthiest screen kiss — between Necar Zadegan and Traci Dinwiddie in 2010’s Elena Undone — which lasted 3 minutes and 23 seconds.

The Study of the Smooch
If you want to learn more about kissing — for purely academic reasons, of course — you may want to pursue a career as an osculologist, which is someone who studies kissing. This discipline, known as philematology, will allow you to do things like look at couples kissing through an MRI scanner, which is how researchers discovered how many muscles we use when we smooch.
Fearful Lips
It’s hardly uncommon for people to occasionally feel nervous when smooching someone, especially during the first kiss. However, for some, this uncomfortable feeling is much more serious. That’s because these people suffer from philemaphobia, a fear of kissing, which may be linked to lack of kissing experience or being afraid of transferring germs with someone when locking lips. If the fear of makeout sessions is intense, it may take some therapy sessions for someone to get over their philemaphobia.
X Marks the Spot
Signing XOXO to signify hugs and kisses may be a cute way to sign a message to someone, but the origins of this practice were born out of necessity rather than beauty. It is believed that in the Middle Ages, people would sign their names with an X if they were illiterate and had no other way of creating signatures. In order to certify that they were being honest, people would then kiss the X made on the document, which over time caused the X to be associated with the act of kissing.
