Molds can grow in different situations. It can cultivate either in cold, damp winter or a warm, humid summer, activities. You might not be aware of it, but mold can possibly be lurking in your home already and is slowly affecting your health. 

But are molds really dangerous? What are the health effects of mold on a person’s body?

It turns out that molds don’t just make your house look ugly, but they are dangerous to your health too. Mold exposure, especially black molds, post a lot of health issues that can become serious when left untreated. Molds are even more dangerous to people who have existing health conditions, including allergy, an existing respiratory problem, or a weakened immune system.


Health Problems Caused By Molds

Breathing Problems

Mold will release spores, cells, fragments, and unstable organic compounds into the air as it develops. Allergens, irritants, and mycotoxins can all be produced by them. Some of these can be harmful, particularly to people who are allergic to them.

Furthermore, moisture causes objects to degrade, resulting in an increase in the amount of molecules, or dust, in the air.

These molecules can cause irritation in the lungs, throat, and nose, particularly in people who have existing breathing disorder, asthma, or a chronic lung disease.



Any individual who has a susceptibility or allergy to mold-related substances may have an allergic reaction.

Mold allergies have indications that are close to those of hay fever or seasonal allergies. Airborne contaminants can also damage the upper respiratory tract in these situations.

Among the signs and symptoms are:

  • stuffy nose
  • runny nose
  • sore throat
  • sneezing
  • watery eyes 

If there is mold in the air, individuals with mold allergies and asthma are more likely to experience an asthma attack.

Dust mites can be attracted to higher levels of dust, which can cause allergic reactions in certain individuals.



Some molds types, including Aspergillus, can develop aspergillosis, a severe health condition in some individuals.

Most individuals are unaffected by inhaling the spores of this fungus, although those with a compromised immune system or who already have a lung disease may have a serious reaction.

There are various Aspergillosis:

  • ABPA (allergic bronchopulmonary aspergillosis) is a form of allergic bronchopulmonary aspergillosis. This has an effect on the lungs which can lead to breathing difficulties.
  • Aspergillus sinusitis is an allergic reaction that involves the nose and can cause a migraine.
  • Aspergilloma, also known as fungus ball, causes coughing that can contain blood, as well as other respiratory problems.

Other Conditions

Mold can also cultivate the growth of bacteria and other pathogens.  According to the World Health Organization, exposure to these bacteria can cause an inflammatory response in some people.

Mold and the bacterial agents it creates, according to the WHO, will increase the chance of bronchial and viral diseases, including pneumonia, bronchitis, allergic alveolitis, and so much more. 


Mold Protection and Prevention

Mold cannot thrive indoors unless moisture levels are regulated. It is also essential to maintain a clean, dry, and well-ventilated house.

Humidity in the home can be caused by a variety of factors, including:

  • people and pets’ breathe
  • water consumption for washing and cooking
  • moisture in the air
  • leaks
  • living in a structure of airtight doors and windows

People should strive for a humidity level of less than 60%, according to the Environmental Protection Agency (EPA) to be able to prevent mold from growing indoors.


Cleaning Mold

  • Wipe down rough surfaces with soap and water, or a bleach solution that has been extensively diluted. To avoid mold recurrence, dry the surfaces after each use.
  • Mold will penetrate porous surfaces, so wash or wipe them down periodically to see if mold has grown again. If the mold keeps reappearing, it’s time to get rid of these things.
  • Antifungal paints and other materials that can help avoid mold growth can be found at your nearest hardware store.
  • To deal with vast areas of mold, hire a specialist.


To Sum It Up…

Mold spores are present across all indoor conditions, but most people are unaffected. People with a weakened immune system, on the other hand, may be at greater risk of illness, especially lung issues, if mold spores and mold are present in air. Other people may have allergic reactions. The easiest way to avoid mold growth is to maintain the indoor area clean, dry, and well ventilated.
