Black mold is made up of several species of mold, which belong to the fungus family. They appear as dark green, grey, or black mass. They are found almost everywhere in the environment, especially in dumps, humid and dark areas. They cause health problems to people when inhaled or ingested, especially people with allergic reactions.
The mold consumes organic substances and moisture. And it releases spores into the air which can be inhaled, ingested, or absorbed through the skin into your body. It is commonly found in wood, cotton, and any other surface that is mostly moist. For instance on dump walls, ceilings, insulation surfaces, carpets, and furniture among others. It is interesting to note that the mold does not grow on glass, metal, or plastic surfaces as they cannot retain moisture.
In homes, black mold is a common phenomenon. It is commonly found in air vents where the spores are circulated. They are found in the air vents because there is a good breeding ground for them, which is oxygen and moisture.
When you inhale or ingest black mold, there are health risks associated. This can manifest in different ways from simple allergic reactions say coughing, and itchy eyes to severe or long-term diseases like lung damage, asthma, brain inflammation, and neurological deterioration, among others. The impact of black mold on your health varies in terms of exposure and the number of spores inhaled. The reaction also varies from one person to another.
The most common effects of black mold on your health include but are not limited to:
- Sour throat
- Difficulty in breathing
