    Yes, I have that twisted nerve too - I sneeze when I shouldn't

    About Tommaso

    I am an experimental particle physicist working with the CMS experiment at CERN. In my spare time I play chess, abuse the piano, and aim my dobson...

    Okay, I am coming out for the interest of Science.

    I read today this article, which does not really say anything new to me, but for some reason triggered my wish to speak up about the condition. The article explains clearly that some people have a twisted connection in their nerves, sort of a short-circuit, which makes them sneeze when they think about sex (others have the same kind of problem making them sneeze when they are looking at bright light sources, e.g. the sun).

    I believe the condition is not as uncommon as it is alleged to be, and the main reason of this underestimate is the fact that people rarely like to speak about such a tale-telling "knee-jerk" reaction that can signal, to the alert observer, the most hidden thoughts in their mind.

    I must say I find the whole thing just amusing, and it does in no means impair my sexual life. Actually, women usually are quite amused when I explain the matter to them. Besides, I quite rarely sneeze during sex; it is more like a reaction to a sexual thought than to the real thing. Still, occasionally it does betray my thoughts to my partner. Not to worry - if you are a keen observer, many other signs will tell you just about as much if not more about the person you spend your time with.

    So why am I telling all this to you ? I guess I would like to say there is nothing really shameful in the matter. The fact that researchers believe this is a uncommon condition, and the dearth of patients who acknowledge it, have probably hindered a deeper study of the phenomenon. I believe it may have a genetic origin, and it would be actually interesting to know more of the topic. Writing about these things here has usually brought more knowledge to me, because the chance that a knowledgeable reader teaches me something is significant.

    None of my friends believe me about sneezing in bright light :(

    I've got the photic sneeze thing, too. You are not alone! :)

    This is way more common than people think. For me it's the same thing every day, go outside, sneeze. I do use it to my advantage too when a sneeze gets stuck I either look at the lights or walk outside. Presto!

    I have the same thing. Coming out of shadow into bright sunlight often makes me sneeze. It's so common I've never heard anyone doubt it.

    My sneezes are also related to sex ---but to that of plants; I only sneeze in the presence of ragweed pollen in the air... :)
    Here's a link to a research paper on the topic you are referring to.

    Hi Tommaso,
    I am far from a biologist, but it seems to me that sexual excitation increases fluid production in the body and that perhaps this may lead also to an increase in wetness in the nose and hence the sneezing--so it is just a symptom of these general factors that come into play?

    Incidentally, please check out the new book, "Higgs," by Jim Baggott. He quotes you there!--as being in the room on July 4 when the 5-sigma announcement was made, and says that he followed your blog on it (I suppose you blogged here, at Science 2.0?). Incidentally, I was in the CMS control room on March 10, 2009 (also other times) when there was a meeting of CMS physicists just as Guido was taking over as spokesman. I wonder if you were in the room then (the power of the LHC was just being upped that day to one of the local "records"--I forget how many TeV's); so we might have met?
    Ciao,
    Amir

    Dear Amir,

    fluids have their dynamics, but this syndrome has nothing to do with them - it is an instant reaction, and quite aptly described as a short-circuit.

    I haven't seen the book yet, thanks for the notice. And no, I was not at the CMS control room back then. But I am sure we'll meet some time, maybe at CERN.

    Cheers,
    T.
    I sneeze when I eat, especially a large or acidic meal. Possibly cross-talk of the H1 (sneezing) and H2 (gastric acid) histamine receptors?

    The light thing is because when you go into the sun, suddenly the temperature changes and the mucoses
    in the nose expand. This enhances the probability you sneeze.
    Never heard about the other sex related sneeze...but interesting.

    dorigo
    No. It is not about mucoses. As explained above, it is leakage current in nerves.
    Cheers,

    I have the bright light one too - and it isn't temperature: sunlight or a bright artificial light work equally well. Never realised it wasn't universal until I told someone and they were mystified.

    italians sneeze better!

    that would make a cool t-shirt.
    talking about the leakage currents, of course ;)

    We've got a lot in common then... not only both particle physicists, but also sex-sneezers :)
    Though I sneeze when I have sexual thoughts about another man :D

    another thing in common... I'm Italian as well :)

    dorigo
    Interesting similarities - but I am only into the other sex ! Anyway thanks for adding to the statistics.

    Cheers,
    T.
