Question

Quizplus · Accepted Answer

The hygiene hypothesis suggests that exposure to microbes, especially during childhood, is important for the development of a strong immune system. This exposure can come from farm animals, other children, and unclean environments. Too much cleanliness and lack of exposure to microbes can lead to an overly sensitive immune system and an increased risk of allergies and autoimmune diseases. The hypothesis does not state that the immune system needs to be protected through very hygienic conditions or that farm animals are more hygienic than household pets. Smoking is also not directly related to the hygiene hypothesis.
