Environmental Factors and Cognitive Health

Environmental Factors and Cognitive Health

Understanding the Impact of Environmental Factors

Our environment plays a significant role in shaping our cognitive health. Factors ranging from exposure to toxins to the quality of our living and working spaces can have profound effects on our brain function.

Toxins and Brain Health

Exposure to certain environmental toxins can have detrimental effects on cognitive health:


  • Heavy Metals: Lead, mercury, and other heavy metals can impair neurological functions and lead to cognitive decline.
  • Air Pollution: Studies have linked air pollution to an increased risk of neurodegenerative diseases like Alzheimer's and Parkinson's.
  • Chemical Exposure: Pesticides, industrial chemicals, and household cleaners can contain neurotoxic substances that affect brain health.​
  • ​Mold Exposure: Exposure to mold and mycotoxins can cause serious cognitive and neurological symptoms for some people.
  • Biological Toxins: Lyme disease and other tick-borne pathogens, viruses, and bacteria can have devastating impacts on brain health.

Dental Health and Cognition

Oral health is intricately connected to brain health, more than many realize:


  • Gum Disease: Chronic gum disease, or periodontitis, has been associated with an increased risk of cognitive decline. Inflammation in the gums and around the teeth can easily be transmitted to the brain, leading to brain dysfunction.
  • Oral Bacteria:  The mouth's microbiome is as important as the gut's. Common oral pathogens, such as P. gingivalis and S. mutans, can potentially lead to neurodegenerative diseases. These bacteria can easily enter the bloodstream and affect brain health.
  • Dental Imaging: Routine dental x-rays or cone beam CT scans can play a crucial role in identifying occult infections or cavitations, especially in teeth that have undergone root canal treatments. These hidden issues, if left unaddressed, can contribute to cognitive problems.
  • Impact of Dental Fillings: Old, broken-down dental fillings can harbor ‘silent’ infections, leading to periodontal disease and exacerbating inflammation in both the mouth and brain. Maintaining good dental hygiene and promptly addressing dental issues are essential steps in safeguarding cognitive health.

Home and Workplace Environment

The spaces where we live and work also influence our cognitive well-being:


  • Mold and Dampness: Exposure to mold and damp environments can lead to respiratory issues and potentially affect cognitive function.
  • Lighting and Air Quality: Adequate natural light and good air quality in living and working spaces can improve mood and cognitive function.

Electromagnetic Fields (EMFs)

While the impact of EMFs on brain health is still being studied, it's important to be aware of potential sources such as cell phones, Wi-Fi routers, and other electronic devices. Until the impact of these frequencies is better understood, it is probably best to avoid nighttime exposure by turning off wi-fi and leaving cell phones and other electronic devices a few feet away from your head or in another room.

Mitigating Environmental Risks

There are several steps you can take to minimize the impact of environmental factors on your brain health:


  • Reduce Exposure: Limit exposure to known toxins and chemicals in your environment.
  • Maintain Oral Health: Regular dental check-ups and good oral hygiene can contribute to overall health.
  • Improve Living Spaces: Ensure good ventilation, reduce mold exposure, and optimize lighting in your home and workplace.
  • Stay Informed: Keep abreast of new research and recommendations regarding environmental factors and brain health.

Detox and Biotransformation

Detoxification and biotransformation are critical components in understanding how environmental factors influence brain health. While many individuals rely on supplements for detox, a truly effective approach encompasses a comprehensive plan. This includes reducing ongoing exposures and assessing the biological burden of potential toxins such as heavy metals and chemicals. Laboratory assessments can provide baseline markers to support detox, including glutathione levels and MTHFR genetics.


  • The Process of Biotransformation: Carried out by the liver, biotransformation supports the modification of chemicals, toxins, or compounds in the body. This process enables these substances to be bound to a transport protein or antioxidant and excreted through the stool, urine, or skin. Successful biotransformation aligns the goals and efforts of the client with the guidance of a health coach.
  • Supplementation that Supports Detox: A supplement regimen for detox depends on the type of toxicity. Common supplements include MTHFR support, bitter herbs, selenium, glutathione, CoQ10, and binders. Personalization of this approach is recommended for optimal results.
  • NIR and Far-Infared Sauna Therapy: This therapy stimulates circulatory support and induces sweating, both essential for transporting toxins through the skin.
  • Air Purification: Toxins can enter our bodies through the air we breathe. Individuals living in highly polluted areas, near freeway systems, or in regions prone to wildfires should consider a plan to circulate and purify the air they breathe.
  • Clean Water: The body is predominantly water, and a clean, purified water source is crucial in supporting biotransformation.

Environmental factors play a crucial role in cognitive health. By being aware of potential risks and taking steps to mitigate them, we can create a healthier environment for our brains and bodies.
