In old houses or in which the insulation is not properly made, moldy dampness can appear on the wall. And although many people think that this is primarily a cosmetic problem, the truth is that it can have serious health consequences.
The main problem with mold on the walls is that it releases spores, which can enter our body by touching or inhaling them and causing various types of irritations and even infections.
A problem for the airways
This is why most of the negative consequences of mold on the walls affect the respiratory tract and not other body systems (although in special cases other organs, such as the eyes or the digestive system, may also be affected), according to the health information from the United States Government .
In addition, it must be taken into account that the presence of mold on the walls is especially dangerous for people who already suffer from certain conditions, such as immunosuppressed or those who suffer from asthma or allergies to fungi.
In these people, mold can cause nasal congestion, wheezing (wheezing in the chest when breathing), and red, itchy eyes or skin. Also, it is believed that it favors the development of asthma in children when they are exposed from an early age.
In the worst case, mold can lead to fungal infections , to which immunosuppressed people are especially sensitive. These types of diseases can have serious consequences and be fatal.
Can it be removed? And prevent?
Once mold appears, there is no way to completely remove all of the fungus or spores from inside a home. Fortunately, its growth can be controlled , according to the Environmental Protection Agency ( EPA ) of the United States Government.
This is achieved mainly by controlling environmental humidity , which is a determining factor in the development of the fungus. However, first it is necessary to clean the area in which the mold has appeared and, if there is it, fix the water leak that may be excessively wetting the wall.
Then the humidity in the room must be reduced to between 30% and 60% relative humidity , which can be achieved through ventilation, dehumidifiers and, if necessary, improving the insulation.
