sneezing while flying helicopter

Hi, I am interested in helicopter flying and may book a lesson, etc.
I have a serious question that perhaps is slightly comical.
I have read lots of info, and it seems to me that a sneeze could be
fatal.
I mean, it's dodgy in a car - more dangerous than adjusting the stereo
perhaps.
To the experienced pilots: if you are flying a helicopter on your own,
how do you handle a sneeze without jolting the sensitive cyclic
control of which you must never let go (or so says some info I read on
the R-22).

Thanks,
Simon.
