Lice and flea infestations
Today we sleep very comfortably in our beds. But in the Old West, the situation was very different. Since the mattresses we know today had not yet been developed, people used hay and straw.
It was a rustic type of mattress that served its purpose, even if it was not the most hygienic option. The problem was that this type of material attracted insects and caused lice and flea infestations among people.
Flies and mosquitoes
It was very common to hear flies buzzing around food. Since there were no refrigerators in the Old West, food could not be stored properly, so everything was exposed.
This meant that mosquitoes and other insects were always contaminating food consumed by humans. As a result, there were more diseases associated with eating contaminated food. There were also no adequate treatments for these problems, and repellents were not yet in use.
