Why do so many school kids get nosebleeds after they e exposed to mold?
This is a difficult question to answer, since noses bleed after many common events. If you watch people in a car, waiting at a stoplight, you’ll routinely see men pick their noses and women fluff their hair. Kids in a classroom are always at their noses. So nosebleeds, commonly caused by nasal irritation and nasal trauma, both from humidity and contact, are a common event. In a group of People Who Denied Nose-Picking, With Unusual Bleeding, including nosebleeds, after mold exposure, we have found hy- peracute changes in C3a affecting changes in clotting. We don’t have the number of kids studied before exposure to answer the question, “do physiologic responses to mold/mold toxins cause nosebleeds?” properly yet. But we’re working on it.
