Why are infants considered more vulnerable to mold exposure?

Infants are considered more vulnerable to mold exposure primarily due to their lower immunity and body weight. Their immune systems are still developing, which makes them less equipped to fend off infections and diseases caused by mold exposure, such as respiratory issues and allergic reactions. Additionally, because infants weigh significantly less than older children and adults, any potential exposure to mold can have a more pronounced impact on their health.

In contrast, the other aspects mentioned, such as activity levels or food consumption habits, are less relevant to their vulnerability to mold. While factors like higher activity levels in older children may influence their exposure to various environmental hazards, it is the combination of a developing immune system and lower body mass that primarily heightens the risk for infants.
