The Dangers of Mold and Mildew and How to Avoid Them?

Room with mold

Whether we like it or not, we need to breathe in order to stay alive. But we end up breathing

a lot of harmful things along with the air. Some of the nasty things always present in the air

are mold and mildew. Few types of mold and mildew have been found causing death in

extreme cases and according to a 2007 study, mold in households directly relates to the

level of depression of the household members. This post talks about what the whole

problem is about, drawing attention to the detrimental effects of mold and mildew on our

health and well being, followed by advice on how to avoid them.


Mold (or ‘mold’), is a type of fungus. They are eukaryotic micro-organisms that are too

small for us to see without a microscope. When a lot of mold starts growing on a surface, it

starts appearing in different colors, including green, blue, or black. Mold spreads by making

spores which are like very small seeds. While it is present everywhere and we are

continuously exposed to it; too much exposure is harmful. It may result in infections, allergic

reactions, or other breathing difficulties. Some types of molds produce mycotoxins which

contribute to a toxic breathing environment for us, our children, and our pets.


Mildew is also another type of fungus, which mostly shows up as a white powdery

substance. It can grow on organic matter, including wood, leather, clothing, and upholstery.

Warmer temperature with high relative humidity is the ideal environment for mildew to

flourish. It is not always harmful, but can trigger minor to serious symptoms in some people –

including respiratory problems and headaches. Some people can also suffer from skin

irritation and burning sensation in the eyes and lungs.


The worst affected are those of us with a compromised or lower immunity, e.g. elderly or

young children. Older people can end up inhaling the mold and the mold can continue to

grow in their lungs. Because their immune system might be weak, it would be difficult for the

body to take care of the invading harmful particles. Once the mold starts growing inside, the

problem gets worse and they start suffering from breathing disorders. In such cases, some

sort of medication is a necessity. Younger children can also suffer from a higher chance of

asthma when exposed to moldy environments. Children with a family history of asthma are

at more risk of developing asthma when exposed to mold. Because children cannot take

care of themselves, the other family members need to make sure such children are

protected from the risk of developing asthma.


The obvious question is then how to avoid something which is present everywhere. The

solution is fairly simple. Keep the home ventilated, warm, and dry. Mold and mildew cannot

grow in dry conditions. Warmer temperatures also avoid condensation from occurring.

Ventilation keeps the air replenished and dissipates the concentration of mildew and mold

growing indoors. We should never let the relative humidity rise above 60% and ideally keep

it under 35%. You can check out this article on how to keep your home dry.


Another consideration in avoiding Mold and Mildew is the temperature of the environment as the

temperature and humidity levels influence each other. Warmer air increases the maximum amount

of moisture that the air can contain and colder air decreases it. At the same time,  dry or less humid

air is easier to heat than air with high moisture levels. A healthy home environment is

based on maintaining a comfortable mix of temperature as well as humidity.
