The Growing Health Problem of Microplastics

Plastics have become an integral part of our modern lives, but they come with a hidden cost. Every year, hundreds of millions of tons of plastic waste are discarded, and over time, these plastics break down into tiny fragments known as microplastics.

What Are Microplastics?

Microplastics are plastic particles smaller than 5 millimeters—ranging in size from a pencil eraser to microscopic fragments. The smallest particles pose the greatest risk to human health because they are pervasive and nearly impossible to avoid.

Microplastics are in the air we breathe, the food we eat, and the water we drink. Alarming research shows they are now found in virtually every organ in our bodies—and their effects on our health are concerning.

The Extent of the Problem

Recycling has not been the solution we hoped for. Only about 9% of plastics are recycled. The rest continues to exist indefinitely in our environment, breaking down into microplastics that enter ecosystems—and eventually, our bodies.

Here are some shocking statistics:

• Washing a synthetic shirt releases 700,000 microplastic fibers into wastewater per cycle.

• When cigarettes burn, they release microplastics into the air, adding to the health hazards of smoking.

• Studies estimate that we ingest the equivalent of a credit card’s worth of plastic each week.

• Microplastics have even been found in the placentas of pregnant women, including every Hawaiian mother tested in a recent study.

And the risks don’t stop there.

The Health Impacts of Microplastics

Microplastics have been linked to serious health concerns:

• Heart Disease and Stroke: A March 2024 study in the New England Journal of Medicine revealed that heart patients with microplastics in their arterial plaque were 4.5 times more likely to suffer a heart attack or stroke than those without microplastics.

• Immune System Damage: Microplastics are toxic to macrophages—immune cells responsible for destroying harmful substances. The more microplastics present, the higher the rate of macrophage death, weakening the immune system.

What Can You Do to Lower Your Risk?

While eliminating microplastics entirely is not yet feasible, there are steps you can take to minimize your exposure:

1. Ditch Bottled Water: Bottled water is the leading source of dietary microplastics. Opt for filtered tap water instead.

2. Choose Glass Over Plastic: Microwave food in glass containers, and store leftovers in glass rather than plastic.

3. Upgrade Your Cutting Boards: Switch from plastic cutting boards to wood. Studies suggest plastic cutting boards expose users to up to 80 million microplastics annually.

4. Opt for Natural Fibers: Reduce your use of synthetic clothing. When you must wash synthetics, use the gentle cycle to minimize fiber shedding.

5. Avoid Single-Use Plastics: Say no to disposable plastics whenever possible. Small changes can add up.

A Call to Action

Until effective solutions for recycling or eliminating microplastics are developed, the best thing you can do is protect yourself and your loved ones. Every step you take toward reducing exposure makes a difference.

Let’s prioritize our health and the health of our planet. Together, we can take meaningful action against the microplastic crisis.
