Mold is a type of fungus that can grow both indoors and outdoors. It can enter your home through open doors, windows, vents, and heating and air conditioning systems. Mold grows best in warm, damp, and humid environments, and can spread quickly through your home.
Mold spores are tiny and can be carried through the air. When they land on a wet or damp surface, they can start to grow. Some people are allergic to mold spores and can have difficulty breathing, a runny nose, itchy eyes, and coughing when they are exposed to mold. People with asthma may have more severe reactions and may have an asthma attack when they are exposed to mold.
If you think you may have mold in your home, you should contact a professional to have it removed. In the meantime, you can try to control mold growth by keeping your home clean and dry, and by using a dehumidifier.
If you or someone in your family has asthma, it’s important to be aware of the potential dangers of mold and take steps to avoid exposure.
