One Explanation for the Increased Incidence of Allergies Is the Hygiene

question 3

Essay

One explanation for the increased incidence of allergies is the hygiene hypothesis. It suggests that a lack of early childhood exposure to infectious agents and later a lack of exposure to helminthes as adults increases susceptibility to allergic diseases. How would you explain why people living in modern hygienic conditions have more allergies? Do you believe they are exposed to more allergens or that having less infectious agents makes one more likely to react to allergens? Explain your decision and describe what experiments or observations would be necessary to support your explanation.
