Mold is a type of fungus that can grow indoors and outdoors. Mold typically thrives in damp, humid environments and can spread quickly through buildings or homes. Some people are more susceptible to the health effects of mold than others, including those with allergies, asthma, or other respiratory conditions.
Mold exposure can cause sneezing, runny nose, congestion, coughing, and watery eyes. In more severe cases, mold exposure can lead to difficulty breathing, wheezing, and fever. Mold exposure can be treated with medication and should be monitored closely by a medical professional.
Here are four health hazards associated with mold exposure and how Bio-One's micro-certified remediation technicians can help you:
1. Allergic reactions
One of the most common health issues caused by mold exposure is an allergic reaction. Mold spores can become airborne and easily inhaled, triggering symptoms in individuals who are sensitive or allergic to them. Common allergic responses include sneezing, runny or stuffy nose, itchy or watery eyes, coughing, and skin rashes. In more severe cases, people may experience wheezing or difficulty breathing—especially those with pre-existing allergies or asthma. If you have any of these symptoms, you must see a doctor as soon as possible.
It’s important to note that even individuals who have never had allergies before can develop sensitivity after prolonged exposure to mold. Children, the elderly, and those with compromised immune systems are particularly at risk. Ignoring these symptoms can lead to chronic respiratory issues and ongoing discomfort.
At Bio-One Oceanside, we understand how serious mold-related allergies can be. Our team uses professional-grade equipment to identify and eliminate mold at the source, ensuring your home or business is safe and breathable once again.
2. Asthma attacks
For individuals with asthma, exposure to mold can be particularly dangerous. Mold spores act as potent respiratory irritants, and when inhaled, they can trigger inflammation in the airways. This often leads to more frequent and severe asthma attacks, which may include wheezing, shortness of breath, chest tightness, and coughing. These symptoms can be severe and can lead to hospitalization. If you have asthma and are exposed to mold, you should see your doctor immediately.
Even low levels of mold in the environment can worsen asthma symptoms, especially in humid or poorly ventilated areas where mold tends to thrive. Children with asthma are especially vulnerable, and prolonged exposure can contribute to long-term respiratory complications.
Controlling mold is a key step in managing asthma and protecting the health of everyone in your home. At Bio-One Oceanside, we don’t just clean visible mold—we locate hidden sources and address moisture issues that allow mold to grow. Our goal is to create a healthier, asthma-safe environment for you and your family.
3. Infections
While most healthy individuals may only experience mild symptoms from mold exposure, for people with weakened immune systems, mold can pose a much more serious risk—leading to invasive infections. Certain types of mold, such as Aspergillus, can cause a condition called aspergillosis, a fungal infection that affects the lungs and can spread to other parts of the body if left untreated.
Those at greatest risk include individuals undergoing chemotherapy, organ transplant recipients, people with HIV/AIDS, or anyone with a compromised immune response. Symptoms of mold-related infections can include persistent coughing, fever, fatigue, and chest pain. In severe cases, these infections can become life-threatening.
That’s why professional mold remediation is critical—not just for comfort, but for safety. At Bio-One Oceanside, we approach every job with health and prevention in mind. Our team identifies hazardous mold species and safely eliminates them to reduce the risk of infections and restore a clean, healthy living space.
4. Skin reactions
Some people may experience skin reactions after coming into contact with mold. These reactions can range from mild to severe, including itchiness, redness, and swelling. Bio-One can help by providing you with the resources and information you need to avoid mold exposure and stay safe if you are exposed. We can also help restore any area impacted by mold.
Preventing Mold Exposure in Your Home or Business
Mold spores are everywhere in the air, and when they find their way into your home or business, they can cause various health problems. Here are some tips to help you prevent mold exposure in your indoor environment:
- Keep things clean and dry: Mold loves damp, dark places. To prevent mold growth, keep your indoor spaces clean and dry. Wipe up spills immediately, fix leaks, and use a dehumidifier to reduce indoor humidity levels.
- Use mold-resistant materials: Use mold-resistant materials whenever possible when building or renovating your home or business. These include mold-resistant drywall, paints, and flooring.
- Get rid of moldy items: If you have any moldy items in your home or business, get rid of them. This includes books, furniture, carpeting, and anything else that has visible mold growth.
- Monitor indoor humidity levels: Use a hygrometer to monitor indoor humidity levels. Aim for relative humidity levels below 60%.
- Use an air purifier: Air purifiers can help remove mold spores from the air, preventing them from causing health problems.
Following these tips can help prevent mold exposure in your indoor environment and protect your health!
