#Asthma

Despite rising rates of allergies worldwide, a new wave of scientific research highlights a surprising exception: Amish children living in traditional farming communities display some of the lowest rates of allergies and asthma ever recorded. This remarkable immunity is now inspiring scientists to unravel the mysteries of the so-called “farm effect” and explore whether its protective elements can be replicated for broader society—a development with important implications for Thai families battling rising allergic diseases.

A growing body of evidence from farming communities suggests that early, regular exposure to natural environments can influence immune development and reduce allergy risk. While Amish children in the United States show notably lower rates of allergic sensitization and asthma, researchers warn that practical, safe adaptations are needed before any broad recommendations can be made for Thailand.

Across the world, urban living and sanitized indoor environments correlate with rising allergies. By contrast, studies indicate Amish children have a skin-prick test allergy rate well below that of most American children. Other farming communities do not reach the same protection, highlighting that the Amish environment may offer unique protective factors worth understanding.
