I read the following quote in a paper:
When you sneeze, all your body functions temporarily stop working. That also includes you heart beat.
There is of course no explanation, reason, source, or reference of any sort.
Is this really true? I don't have a heart rate monitor at my hands fast enough when the urge to sneeze comes up, so I can't test for myself.
If it is really true, I would also like to understand why.
