Sneezing 'can be sign of arousal'
A simple sneeze may be a tell-tale sign of sexual arousal for a select few, research suggests.
Two British doctors investigated the phenomenon after reading of a middle-aged patient who had uncontrollable sneezing fits when he thought of sex.
They unearthed evidence, via internet chat rooms, of 17 others - of both sexes - with the same problem.
The Journal of the Royal Society of Medicine study suggests it may be down to a mix-up in brain circuitry.
The researchers, Dr Mahmood Bhutta and Dr Harold Maxwell, also uncovered three people who claimed to sneeze after orgasm.
Dr Bhutta, a specialist in ear, nose and throat medicine at Oxford's John Radcliffe Hospital, said the phenomenon could be more widespread than thought and might even be inherited.
