the case for building resilience against modern toxins through sauna

Stay with me through this one.

We will loop back around to why sauna use matters, but first we need to talk about something that affects all of us living in the modern world: modern chemical exposure.

Many of the materials that make modern life convenient – plastics, synthetic fabrics, food packaging, nonstick cookware, personal care products, and building materials – introduce compounds that the human body did not evolve alongside.

This is not about fear. It is about awareness.

Because awareness allows us to support the body’s natural ability to maintain balance.

And that is what we are here for – to support balance.

Maintaining a strong immune system and resilient cellular function is increasingly important in our modern environment where exposure to synthetic compounds is unavoidable. Supporting the body’s natural defense systems helps sustain energy, recovery capacity, and long-term vitality.

Practices that help support circulation, metabolic health, and cellular resilience may play an increasingly important role in how we care for our health

Plastic-Associated Chemicals in Modern Life

Certain compounds associated with plastics – including bisphenol A (BPA) and phthalates — are categorized as endocrine-disrupting chemicals, meaning they may interact with hormone signaling pathways.

Environmental epidemiologist Shanna H. Swan has contributed extensive research examining how long-term exposure to endocrine-disrupting chemicals may influence reproductive and developmental health patterns.

Studies measuring human exposure have detected BPA and phthalate metabolites in blood, urine, and tissue samples, indicating that exposure is common in modern environments.

Because these compounds are so widespread, researchers are increasingly interested in understanding how the body processes and eliminates them.

What Research Shows About Sweat and Environmental Compounds

A peer-reviewed study published in the Journal of Environmental and Public Health evaluated the presence of environmental chemicals in blood, urine, and sweat samples.

Researchers observed that BPA was detectable in sweat, sometimes even when it was not detected in blood serum. Similar findings have been observed with certain phthalate metabolites.

Heat exposure and sweating have been shown to support elimination of certain environmental chemicals associated with plastics, such as BPA and phthalates.

Research on direct removal of microplastic particles themselves is still emerging.

Microplastics differ from BPA and phthalates because they are physical particles rather than dissolved compounds, and scientists are still working to understand how these particles interact with human tissues and elimination pathways.

The body’s primary detoxification systems remain the liver, kidneys, digestive tract, and lymphatic system. Sweat appears to function as one supportive pathway among many.

Heat Exposure and Human Adaptation

Research frequently cited by Rhonda Patrick has explored the relationship between sauna use and cardiovascular health, metabolic function, and longevity.

Large Finnish population studies have associated regular sauna use with:

• improved cardiovascular outcomes
• reduced inflammatory markers
• improved circulation
• reduced all-cause mortality risk

Heat exposure stimulates heat shock proteins, which play an important role in cellular repair and stress adaptation.

Andrew Huberman has also discussed deliberate heat exposure as a form of controlled environmental stress that may support resilience within the nervous system.

Short periods of manageable stress – including heat and cold exposure – may help the body maintain adaptive capacity over time.

Mushrooms and Environmental Resilience

In nature, fungi play an essential role in breaking down complex materials that would otherwise persist in ecosystems.

Research in the field of mycoremediation has demonstrated that certain mushroom species are capable of degrading petroleum products, pesticides, and industrial pollutants through specialized enzymatic processes.

Mycologist Paul Stamets has studied how fungal networks interact with environmental contaminants, demonstrating the remarkable biochemical capabilities of fungi to transform complex compounds.

While mycoremediation occurs in ecosystems rather than inside the human body, compounds found in medicinal mushrooms have been studied for their ability to support immune function and antioxidant activity.

Mushrooms contain bioactive compounds including:

• beta-glucans
• ergothioneine
• polyphenols
• triterpenes

These compounds are associated with supporting cellular defense mechanisms and helping protect against oxidative stress.

Oxidative stress is one of the biological processes involved in how the body responds to environmental exposures.

Eating mushrooms does not remove microplastics directly, but nutrient-dense foods may support the body’s ability to maintain resilience.

A Full Systems Approach to Modern Wellness

Supporting long-term health is rarely about a single intervention.

It is about consistent supportive inputs.

Movement supports circulation.
Sleep supports repair.
Heat supports metabolic activity.
Cold exposure supports nervous system regulation.
Nutrient-dense foods support cellular resilience.

Sauna use is one component of a broader lifestyle approach that encourages the body to maintain balance in an increasingly complex environment.

While research on microplastics continues to evolve, existing evidence suggests that heat exposure supports physiological systems involved in recovery, circulation, and stress adaptation.

So yes – eat the mushrooms. I sell Cymbiotika Longevity Mushroom blend in store.

Support your body’s natural systems. Like eating whole foods, and taking vitamins and supplements.

Use the sauna. Get some vitamin D.

Return to the ritual. Live your best life.
