A recent study by the scientists of Singapore’s Nanyang Technological University (NTU) found that the rural environment of the Amish community, a traditionalist Christian group largely living in the farming belts of Pennsylvania and Ohio, could be less conducive for the development of asthma. They also found that Amish farms had lower rates of asthma, as compared to children growing up in other farms. The researchers ascertained that this could be because the residents could be exposed to a diverse variety of allergens as they are growing up. 

The researchers also added that their further research also established the precise chemical compounds present in dust that are responsible for protection against asthma in children.
