What health issue can mold exposure exacerbate in sensitive individuals?

Mold exposure is especially known to impact individuals who have existing sensitivities, such as those with allergies or asthma. In sensitive individuals, mold can trigger allergic reactions, leading to symptoms such as sneezing, runny or stuffy nose, itchy eyes, skin rashes, and respiratory distress. Asthma sufferers may experience worsened symptoms, including increased frequency and severity of asthma attacks, due to mold spores acting as allergens that irritate the airways.

The biological mechanisms involve the immune system reacting to mold spores as foreign invaders, which can lead to inflammation in the respiratory system, making it more difficult for affected individuals to breathe. Thus, the relationship between mold exposure and the exacerbation of allergies and asthma is well-documented, and it's crucial for sensitive individuals to minimize their exposure to mold to maintain their health.

Given this well-established link, it's clear why this particular answer is the most accurate choice when discussing the health issues that mold exposure can worsen.
