Which of the following symptoms can be caused by exposure to mold?

Exposure to mold can lead to a variety of health symptoms, particularly respiratory issues. Shortness of breath and sneezing are common reactions when an individual inhales mold spores or their by-products, which can irritate the airways and trigger allergic responses. Many people may be sensitive to mold and can experience symptoms ranging from mild irritation to more serious respiratory problems, especially those with pre-existing conditions such as asthma or allergies.

The other options do not accurately reflect symptoms associated with mold exposure. For instance, increased energy levels and improved digestion are not recognized reactions to mold; in fact, mold exposure typically leads to fatigue or digestive disturbances in sensitive individuals. The mention of headaches from too much fresh air is also misleading, as headaches related to mold are usually a response to indoor air quality issues, and not fresh air exposure. Understanding these implications is crucial for recognizing the health risks associated with mold in our environments.
