Our body is a well-set clock, which keeps good time, but if it be too much or indiscreetly tampered with, the alarm runs out before the hour.

Study confirms microplastics are getting into brain tissue
Microplastics in the Brain: An Unsettling Reality and How to Fight Back
Let’s start with a shocking number: Scientists in the U.S. have discovered around 7 grams of microplastics in the brains of deceased individuals.
That’s roughly the weight of a tablespoon of salt. Now, if you were to mix a tablespoon of salt into 1.4 kilograms of ground beef (the average weight of a human brain), your burger would be inedible.
Except, here’s the disturbing part: Microplastic particles are about 5,000 times smaller than a grain of salt.
So, 7 grams is far more than a mere tablespoon—it’s billions of plastic particles lodged inside our brains. If researchers found this much in just a few brains, how much is accumulating in mine? In yours?
How Did Plastic Get in My Brain?
The short answer: We’re constantly surrounded by microplastics.
They form as plastic waste breaks down, tire particles wear off on roads, and synthetic clothing sheds fibers. These tiny plastic particles enter our bodies through the air we breathe, the water we drink, and the food we eat.
More concerning are nanoparticles—so small they can breach the intestinal wall, enter the bloodstream, and travel directly to our organs, including the brain.
Scientists have found that the amount of microplastics in our environment is rising dramatically.
In a study comparing brains from 2016 to those from 2024, microplastic levels increased from 4.6 grams to 7 grams. That’s a nearly 50% increase in just eight years.
The longer we ignore this issue, the worse it gets.
Does Microplastic Make Us Sick?
Here’s where the debate gets heated. No one can say with certainty what microplastics do inside our bodies—but early findings aren’t comforting.
In lab experiments, microplastics kill cells. In fish, they alter DNA. In mice, they reduce fertility, damage the liver, and cause inflammation.
And in humans?
Scientists discovered that brains of dementia patients contained five times more microplastic than those of other individuals.
Other studies have linked microplastics in blood vessels to an increased risk of heart attacks and strokes.
Still, some argue that correlation doesn’t equal causation. Maybe microplastics are a symptom of modern pollution, not the root cause of these diseases.
But do we really want to wait for decades of studies to confirm what common sense already suggests?
How to Reduce Your Plastic Intake
While governments drag their feet on real action, we can take steps to protect ourselves:
Filter Your Water: Tap and bottled water contain microplastics. Install a high-quality water filter that removes particles down to the nanometer scale.
Ditch Plastic Packaging: Store food in glass or stainless steel containers instead of plastic.
Avoid Processed and Packaged Foods: Fresh, unprocessed foods contain fewer microplastics than prepackaged meals.
Choose Natural Fibers: Clothing made from polyester, nylon, or acrylic sheds microplastics in the wash. Opt for cotton, wool, or hemp instead.
Limit Seafood Consumption: Fish and shellfish ingest microplastics from the ocean, meaning they pass directly to you.
Ventilate Your Home: Indoor air contains microplastic particles from carpets, furniture, and dust. An air purifier with a HEPA filter can help.
Support Plastic Bans: Push for policies that limit plastic production and waste.
A Call for Change
Microplastic pollution is not just an environmental issue—it’s a direct threat to our health.
We are the first generation to live with plastic in our brains, and we may also be the last generation able to do something about it before the damage becomes irreversible.
If you don’t want your brain slowly filling with plastic, start making changes today.
Because while we wait for absolute proof that microplastics are harmful, they continue to accumulate in our bodies, unseen and unchecked.
And that’s a gamble we shouldn’t be willing to take.
