Question

How has modern lifestyle affected immunity and allergen sensitivity?

Options

• Modern lifestyle has enhanced immunity and decreased allergen sensitivity

• Modern lifestyle only affects bacterial infections, not allergies

• Modern lifestyle has lowered immunity and increased sensitivity to allergens

• Modern lifestyle has no effect on immunity or allergen sensitivity

Answer 1

Modern lifestyle has lowered immunity and increased sensitivity to allergens. This paradoxical effect occurs despite advances in hygiene and medicine. The extensive use of antibiotics, reduced exposure to diverse microorganisms in early life, and highly controlled indoor environments prevent normal immune system maturation and training. Additionally, environmental pollution, increased stress, and altered dietary patterns further compromise immune function, leading to increased allergic disease prevalence in developed nations.
