Japan has had a pretty good track record with the annual Ig Nobel Prize. Scientists from all over the country have been awarded for nine years straight for their contributions to wacky and humorous research. Last year, Professor Kiyoshi Mabuchi recieved the Ig Nobel Prize in Physics for determining exactly how slippery a banana peel on the floor is.
Now, Dr. Hajime Kimata of the Osaka Prefecture Neyagawa Allergy Clinic has been given the Ig Nobel Prize in Medicine. However, rather than investigating a silly topic, Dr. Kimata’s findings were actually rather sweet: Kissing can reduce a person’s allergic reactions.
In a 2003 study, Kimata examined a group of 60 subjects with either hay fever or allergic eczema as well as a control group of 30 people with no allergic problems. The subjects all claimed to not kiss on a regular basis.
Kimata then provided them with a private room in which they were instructed to make out for 30 minutes straight with their significant other. Because he’s an old softy, Kimata arranged soft music to be piped into the room as well.
▼ I don’t think this was where the music came from…but I’m not 100 percent sure of that.
Interestingly the allergy sufferers showed a decrease in skin reactions to dust mites and Japanese ceder pollen after their make-out session. There was also a decrease in certain neurotrophins and growth factors (proteins) found in their blood plasma. On the other hand, no change in these proteins was observed in the subjects who did not suffer from allergies after kissing.
In 2004 Kimata took things to the next level and tested the effects of sex on allergic skin rashes. The results were similar to kissing in that “sexual intercourse significantly reduced skin weal responses induced by Japanese cedar pollen or house dust mites.”
▼ The Ig Nobel Prize in Medicine was shared with a team from Slovakia who determined that you can extract the DNA of a man from a woman’s saliva up to an hour after they kissed.
Finally, in a 2006 study, Kimata observed that kissing also triggers a reduction in immunoglobin E (IgE) production which is associated with all kinds of allergies from hay fever to asthma.
Dr. Kimata was unable to attend the awards ceremony on September 17 due to a scheduling conflict, but he sent a video message from the clinic where he works as director.
There you have it folks. You now know how to beat atopic dermatitis in certain reactions, so get out there and start sucking face. Even if you don’t have anyone to kiss at the moment, some people have developed work-arounds.
