What is Mold?

Mold is a fungus and comes in many different forms. Most people worry about so-called "black mold," which may refer to the mold known as Stachybotrys chartarum (S. chartarum). There is some concern that this mold releases toxic substances known as mycotoxins. However, thereā€™s no evidence that this mold is any more dangerous than any other type.

If youā€™re otherwise healthy and your immune system is strong, you shouldnā€™t have any problems with mold in low quantities. Itā€™s only when thereā€™s a lot of mold that it becomes dangerous to almost everyone.

However, if your immune system is weak or youā€™re sensitive to this fungus, then you may experience a range of mold exposure symptoms or health problems to even small quantities.

Common Mold Exposure Symptoms

The mycotoxins that some molds produce can cause mycotoxicosis, often called mold poisoning, in large quantities. Some of the symptoms associated with this issue include:

  • Nosebleeds
  • Coughing
  • Memory loss
  • Headaches
  • Mood changes
  • Sore throat
  • Aches and pains
  • Wheeziness

However, at this stage, thereā€™s no evidence that mold spores cause these symptoms. There is also no evidence that it causes cancer or lung disease or any rare health conditions at all.

People at Higher Risk of Mold Sensitivities

However, if youā€™re sensitive or exposed to high quantities, you are more likely to experience mold exposure symptoms. People who may be sensitive to mold include:

  • People with other allergies
  • The elderly
  • Infants and children
  • People with chronic lung disease
  • People with asthma
  • People who have conditions that compromise their immune systems

Mold Allergies

If your body has developed an allergy to mold, you are more likely to experience more severe symptoms. Some of the signs that youā€™re allergic to mold include:

  • Runny nose
  • Red eyes
  • Sneezing
  • Wheezing
  • Skin rash
  • Sore throat
  • Sinusitis
  • Shortness of breath in severe cases
  • Asthma attacks in people with asthma

If you have an allergy, talk to your doctor about the issue. You can also help to reduce your symptoms by:

  • Wearing a dust mask while gardening.
  • Closing doors and windows at night when mold spores are likely to be around.
  • Avoiding the outdoors after rain or in damp weather.

What To Do if You Have Mold Symptoms

Thereā€™s no test that can show youā€™ve been exposed to mold. However, if you experience mold exposure symptoms, then you should still see your doctor first. This is particularly true if youā€™re experiencing problems with your breathing.

However, your doctor will be able to review your symptoms and test for mold allergies. This allergy can get worse over time, so itā€™s important that itā€™s identified so you can take action.

To test for allergies, your doctor can perform a blood test to test for certain antibodies to mold. They may also do a skin prick test and apply a tiny piece of mold to your skin. If youā€™re allergic, then the patch of skin will break out with a rash, bump, or hives.

The Medical Approach to Mold Exposure Symptoms

The best way to get rid of mold exposure symptoms is to remove the mold from your home and anywhere else you find it. However, there are some strategies that can help alleviate your symptoms, particularly if theyā€™re severe. These strategies may include:

  • Over-the-counter medications to counter any allergic reactions such as antihistamines.
  • Nasal sprays or rinses that remove mold from your nasal passages and help calm congestion.
  • Medications to reduce mucus and allergy symptoms.
  • Allergy shots or low dose immunotherapy.
  • Binders to take out biotoxins in your body from the mold.
  • Lab test monitoring to track Chronic Inflammatory Response Syndrome (CIRS).

How to Control Mold

An image of a person in protective gear removing mold from a wallYou may not be able to completely rid your home of mold and its spores to avoid mold exposure symptoms. However, you can kill mold on surfaces and avoid creating the dark, damp places mold needs to grow. Hiring a professional is probably the best way to find and remove hidden pockets of mold. However, you can do the following yourself:

Find the Mold

Make sure that you protect yourself from further mold exposure symptoms by wearing a mask and gloves when youā€™re looking for or removing mold. You can also wear rubber boots, goggles, or a mold-resistant suit.

Look in dark, warm, moist places for clusters of mold. You should also look for issues that cause dampness in your home such as leaks, water damage, old food, or papers where mold can grow.

Remove the Mold

Once youā€™ve found any clusters of mold in your home, make sure you fix the water leak, humidity, or other problem that caused them. You should also throw away any soft and porous material that the mold is growing on.

Once thatā€™s done, you can use a commercial mold removal product to remove mold from hard surfaces that canā€™t be thrown away. A solution of 10% bleach and 90% water can be used in some cases. Afterward, make sure the area is well ventilated.

Prevent Further Infestations

Once youā€™ve removed any mold that you can see, itā€™s time to work on prevention. There are lots of things you can do to prevent or minimize mold growth in your house. These include:

  • Monitor the humidity in your home using a hygrometer, which can be bought at hardware stores. Aim to keep indoor humidity below 50%.
  • Clean problem areas often such as kitchens or bathrooms.
  • Use a dehumidifier to reduce moisture in the air.
  • Make sure you fix any leaks or seepage as quickly as possible.
  • Keep your house warm in cold weather to prevent condensation.
  • Keep your air conditioning drip pans and drain lines clean.
  • Make sure your air conditioners and heater are working properly at all times.
  • Keep the air circulating in your home with fans or by keeping doors and windows open when possible.
  • Add insulation to exterior floors, windows, and walls to reduce condensation.
  • Use exhaust fans in the kitchen and bathrooms.
  • Regularly inspect spaces for mold.
  • Clean up any mold you find as soon as possible.
  • Avoid using carpet in kitchens and bathrooms and dispose of carpets that are flood-damaged.
  • Donā€™t keep old books or other paper products around moisture sources.
  • Make sure that your rain gutters are clear and are directing water away from your house.

Mold and Adrenal Fatigue

Any mold exposure symptoms that you experience may cause or worsen adrenal fatigue. Adrenal fatigue is a common complaint because of chronic stress. Many people in the world are constantly stressed these days because of our lifestyles, environmental problems, relationships, and work. The human body just isnā€™t designed to cope with constant stress, and this can result in Adrenal Fatigue Syndrome (AFS).

When stress is temporary, the NeuroEndoMetabolic (NEM) stress response activates during stressful periods. It helps resolve the stress and gives you the energy and the focus to cope with the cause of the stress. However, when stress becomes chronic, this system is overused and becomes unbalanced.

Cortisol is an essential part of the NEM stress response. Itā€™s released by the adrenal glands and affects every circuit in your body, preparing you to cope with stress. But if your stress isnā€™t alleviated, the body continues to demand cortisol on an ongoing basis. The adrenals become fatigued from the high workload and can start to fail. This can lead to a whole range of problems and health concerns as the bodyā€™s circuits become unbalanced and malfunction.

Detoxification and Mold Exposure Symptoms

An image showing the position of the liver in the bodyThe Detoxification circuit is the set of organs and systems responsible for eliminating harmful and nonharmful substances from your body. It consists of the immune system, the liver, and the extracellular matrix (ECM, or the spaces between cells).

The most important duty of this circuit is to remove metabolites from the body. These are substances that are produced by your metabolism in the normal process of operations. When youā€™re healthy, these metabolites are deactivated and expelled in the background and youā€™re not aware of them.

But malfunctions in the Detoxification Circuit and the excessive build-up of metabolites can impede this process and have serious health effects.

Here's how mold exposure could affect the Detoxification Circuit and AFS as a whole:

Immune Overreaction

When you have AFS, allergies, or autoimmune issues, your immune system is often overactive. This contributes to inflammation and increased susceptibility to infection and illness. Mold exposure symptoms will only worsen immune system overactivation, creating a constant threat, and can thus worsen Detoxification issues, AFS, and other conditions as well.

Constant stress also increases your chances of developing mold allergies or other reactions to the mold spores. When the immune system is overactive, allergies become more common and frequent, putting additional stress on the body.

Malfunctions in the immune system also make you more susceptible to developing fungal infections as a result of exposure to mold spores.

ECM Congestion

The ECM is the fluid-filled spaces between the cell walls. This is where chemical messages travel between the cells. These spaces can become clogged with metabolites, impeding the communication between the cells. If this situation isnā€™t alleviated, the ECM can become completely congested with metabolites.

Mold exposure symptoms or allergies will cause more stress and the production of more metabolites. This will add to the congestion in the ECM, causing more inflammation and more stress.

The Liver

The liver is responsible for deactivating and expelling harmful metabolites. But as metabolite numbers build because of stress and malfunctions with the immune system as well as adrenal fatigue, liver function can start to slow down. Metabolites then build up in the liver and are released back into the bloodstream and the ECM without being deactivated. This can result in greater numbers of toxic metabolites in the ECM, worsening immune system overactivation and dysfunction.

When this occurs, you will be more likely to react badly to mold spores. You will also be more likely to develop an infection from them.

The Takeaway

Mold is generally harmless in small amounts, but itā€™s still important that you remove it from your home. If youā€™re unwell or the mold spreads, then you may experience a range of mold exposure symptoms that will not only impact your immediate health, but that could have long-term consequences. Hereā€™s what you need to know about mold exposure:
