In the "previously on the Box" clip, one of the contestants develops hay sneeze from bales of hay. Actually, hay sneeze is an allergic reaction to pollen produced by flowering parts of living grass, whereas hay is a grass dead, dried and sometimes compacted. There should be no pollen in such hay as presented in the clip, unless the pollen was artificially added for the effect.
Some people suffer from dust allergies as well as pollen allergies. Hay, being a dead grass, contains a large amount of dust. It fills the air and irritates the nose. Enough to make anyone who suffers from such an allergy to have a strong reaction being enclosed with it in a confined space.
