Reduced Nature Exposure Linked to Rising Immune-Mediated Inflammatory Diseases

Scientific research suggests that rapid urbanization and lifestyle shifts are disconnecting humans from natural microbial environments, contributing to a rise in immune-mediated inflammatory diseases (IMIDs).

Conditions such as Crohn’s disease, asthma, and type 1 diabetes are increasingly linked to a lack of early-life exposure to microbial diversity, which is essential for developing immune tolerance.

The 'Old Friends Hypothesis' posits that the immune system requires 'training data' from natural environments during the first five years of life to properly distinguish between threats and harmless antigens.
