Every week, the average person ingests the equivalent weight of a credit card in plastic.* While certain preventive measures can significantly reduce your intake of these harmful substances, it’s crucial to acknowledge a more daunting concern: the bioaccumulation of microplastics in the brain, potentially at ten times the rate of other organs. Microplastics and their associated chemicals are alarmingly ubiquitous — they permeate breast milk, sperm, the hippocampus, the prefrontal cortex, the air we breathe, medications, the water supply, and our bloodstream, accumulating in most major organ systems. During this episode, we’ll explore the unsettling realities of microplastics and their associated chemicals, diving into how they infiltrate nearly every facet of our environment and body, and discuss actionable strategies to reduce exposure.

Sweating modestly contributes to enhancing microplastic-associated chemical excretion. Get my free sauna report when you sign up for my newsletter: [ Ссылка ]

* Some sources suggest this figure may need to be revised downward due to disagreements over the underlying calculations. Nevertheless, despite the lack of consensus, human and animal consumption of microplastics remains substantial and widespread.
