Fortunately you don’t need to!

Upon sneeze initiation of non-voluntary inhalation and the iconic “Ah-” you can consciously react with a valsalva maneuver* of the airway by retracting your tongue up toward your nasopharynx - try it now while exhaling, and if done correctly your exhale should be fully blocked and you’ll feel a slight pressure increase in your head. Doing this after that inhalation portion of a sneeze will similarly block the “-choo!” half, keeping the air and slurry of snot and pathogens all internal, at the cost of making yourself subtable to the consequences listed in OP’s article.

 

*not to be confused with a valsalva maneuver of the GI tract, which can cause hernias and a vasovagal response that dips your blood pressure and can make you pass out
