Children raised in overly sterile environments are more prone to allergies, as their immune systems lack the necessary challenges to develop properly. This phenomenon is highlighted by the "Farm Effect," which suggests that early exposure to diverse microbes, particularly through contact with livestock and unprocessed dairy, can protect against conditions like asthma and hay fever. Discussions emphasize the contrast between children raised in clean, controlled settings and those who grow up in rural areas with regular exposure to dirt and animals, with the latter group showing better health outcomes. Epidemiological studies support the idea that environments rich in microbial diversity, such as farms, enhance immune system development. The Helmholtz Institute Munich has conducted significant research on this topic, reinforcing the importance of microbial exposure in early life for long-term health.
