To Suppress Sneezing, Press Your Tongue Against the Roof of Your Mouth.
Suppressing sneezing can be the cleanest and simplest bodily hacking. We’ve already published a couple of methods (pulling the nose, sticking a finger under it, or biting the lip), but instead, I’ve always relied on pressing my tongue against the palate. (You can also tickle instead of pressing .)
This is mainly due to overloading the brain with benign sensory signals in order to dull more unpleasant signals. This is why the same tongue maneuver can help fight stagnant brains or stop crying over onions .
If you do want to sneeze, try staring at the sun. This will only work for a fifth to a third of the population , but this trick is as old as Aristotle .
