Mold: What It Is, Why It Happens and How to Deal With It

Mold: What It Is, Why It Happens and How to Deal With It

Many people assume they are safe from mold if they follow the basic rules of cleanliness, but the truth is that mold is more pervasive than most of us realize. In fact, many troubling symptoms can be traced back to hidden sources of mold. The good news is that many natural remedies and easy preventative measures exist.

Why Is Mold Problematic?

Mold is a type of fungus that thrives in moist conditions, both outside and inside. It is essential to the environment – in the outdoors! – because it breaks down things like dead leaves. 

Mold is more problematic indoors, where it favours damp, dark places like basements or poorly ventilated bathrooms. It can also grow in wet carpet, on window sills, or in drywall. Even dishwashers and washing machines can harbor mold! And anyone who has ever forgotten to empty a lunchbox or thermos may have had an unpleasant encounter with mold.

When mold is growing indoors, its presence is not just limited to visible patches. Mold produces tiny spores and volatile organic compounds (VOCs) that spread through the air. In other words, a room may look clean, but if there is a small patch of mold growing in, for example, a corner of a window sill, people in the room may be breathing in mold spores and VOCs. Some people are sensitive to these spores, some preexisting conditions are exacerbated by it, and people have allergies to mold.

Mold exposure is a common unrecognized cause of hormonal imbalance. Mold toxins can either enter your body through your nose or gastrointestinal tract causing disruptions in hormonal mechanisms. Since hormonal systems work like a spider web, disruptions caused by these mycotoxins can upregulate or downregulate hormone production. The major systems affected by mycotoxins are the immune, neurologic, and gastrointestinal systems. In females, mold toxicity can cause imbalances in the production of estrogen, progesterone, DHEA, and testosterone that may lead to infertility, endometriosis, irregular menstrual cycles, depression, weight gain, breast enlargement, and Premenstrual Syndrome (PMS). For males, the production of testosterone is affected leading to low motivation or low libido, prostate issues, and diabetes. If you think this could be a problem for you, please contact your doctor to get tested.

Symptoms Of Mold Exposure

The effects of mold on the body are often cumulative, meaning that they build up over repeated exposure. Some common symptoms include:

  • Headaches
  • Fatigue
  • Nosebleeds
  • Unexplained muscle aches
  • A runny nose
  • Sore throat
  • Coughing
  • Eye sensitivity
  • Watery eyes
  • Nausea
  • Changes in appetite
  • Night sweats
  • Unexplained skin rashes
  • Hormone issues

These symptoms are more likely to appear in children, older people, or the immunocompromised though anyone can be affected by mold. Roughly 5% of the population has allergic responses to mold, which can trigger respiratory symptoms like wheezing and sneezing. Alarmingly, mold exposure may also be linked with a higher rate of depression, although more research needs to be done in this area.

Long-term exposure to mold can produce more serious effects in young people. One study found that children exposed to mold in their early years performed lower in cognitive assessments. Another linked mold exposure to an increased risk of asthma in children.

Mold In Our Food

Nobody likes to see mold on their food, and in some instances, the effects on your health can be serious, particularly for people with mold allergies. Some food molds produce poisonous and even carcinogenic substances called mycotoxins. Fruits, vegetables, bread, and cheese are foods particularly prone to mold. If a soft food, such as bread or berries has spots of mold, throw out the entire thing, as it’s possible invisible spores have permeated the rest of it. Don’t sniff the mold before you toss it, since you could inhale mold spores. Just assume it doesn’t smell very good!

Tips For Preventing Mold Exposure

Keep an eye out for moisture

Mold needs moisture to grow, so the first step to keeping mold at bay is to identify any sources of water or moisture.

  • If you see mold in a room, look for water leaks immediately.
  • Always use the bathroom fan when showering or bathing.
  • Maintaining HVAC systems is essential.
  • Use a dehumidifier if moisture is a problem in an area where it’s hard to address, such as damp crawl spaces.
  • When in doubt, throw out. Mold grows rapidly and is often hard to see initially. If a household item like a damp rug has a bit of mold, replace the whole thing.

Non toxic cleaning solutions

Although household bleach can effectively kill mold, it carries health risks of its own and should be avoided. Here are some alternatives you can try:

  • Tea tree oil is an excellent alternative. Just mix two teaspoons with two cups of water, and spray on affected surfaces. Let it sit for at least an hour before wiping clean with a scrub brush.
  • Baking soda is another good, non-toxic choice – just add some to water and spray.
  • Undiluted white vinegar can also kill mold. It’s cost effective, non-toxic and don’t worry about the smell – eventually the vinegary smell fades.

Natural remedies for mold exposure

If you’ve been exposed to mold and are experiencing reactions, the obvious first step is to remove the mold, as outlined above. As your body restores itself, you can take some steps to help detoxify.

  • Raw garlic has natural antifungal properties. You can include fresh raw garlic or tablets, however speak with a practitioner about any specific dosage for you.
  • Activated charcoal binds itself to toxins in mold to slow or stop its spread. Taken internally, activated charcoal tablets can help rid your body of mold trapped inside. Again, speak with a qualified practitioner to see if this supplement is right for you.
  • Chlorophyll not only has antifungal properties, it also protects our DNA from damage from toxins. Green leafy vegetables are an excellent source of chlorophyll, as are phytoplankton and
  • A sugar-free diet inhibits the growth of fungus.

Mold is not the most pleasant topic. It can be disturbing to find some in your own home and even worse it can negatively affect your health without you knowing it if you can’t pinpoint the source.

Taking a proactive approach and doing all you can to prevent mold exposure can lessen the impact of mold on your health. If you have any questions, give us a call and let’s talk!
