Why pollen did not make hay fever look like a farm disease

Hay fever is an allergic reaction: after the immune system becomes sensitive to pollen, it can treat otherwise harmless particles as a threat. On later exposure, the body releases chemicals such as histamine, which can cause sneezing, a runny nose, and itchy eyes. The symptoms depend on immune sensitivity, not simply on how many hours someone spends near plants. Regular exposure alone does not guarantee protection, and the historical reports do not establish that agricultural workers were immune.

Who had the time—and standing—to be noticed

In the 1800s, wealthy people were more likely to describe their symptoms as a distinct condition and have them recorded. Their indoor routines also made the seasonal contrast conspicuous: someone who spent much of the year away from fields might notice a sudden bout of symptoms during time outdoors. For a farmworker, discomfort amid the ordinary demands of outdoor work could be less likely to become a fashionable medical complaint—or to enter the same written record.

That imbalance shaped the condition’s social meaning. When accounts associated it with people of leisure rather than laborers, hay fever could seem like evidence of refinement or a delicate constitution. The pattern tells us as much about who reported illness and whose experiences were documented as it does about who encountered pollen.
