Why a few small changes in everyday life may be worth making
For most of my life, I never thought very much about plastic. It was simply part of the background of everyday life—the water bottle in my car, the containers holding leftovers, my workout clothes, the cutting board in the kitchen, the coffee cup I picked up on the way to work.
When I first heard people talking about reducing their exposure to plastic, I will admit that I didn’t completely understand the concern. Plastic was everywhere. Surely if it were really a problem, wouldn’t we all know about it?
Then I started reading the research, and I began to understand why this conversation has changed so much.
Scientists are now finding tiny plastic particles, known as microplastics and nanoplastics, in places we never expected them to be, including human blood and tissues. At the same time, researchers have spent years studying chemicals used in certain plastics, including phthalates and bisphenols, because some can interfere with the body’s hormone signaling. Studies have associated higher exposure to some of these chemicals with changes in reproductive hormones, fertility measures and other health outcomes.
There is still a great deal we don’t know. Finding a microplastic in the body does not automatically tell us what effect it will have, and it would be irresponsible to suggest that every interaction with plastic is dangerous. But for me, the research changed the question.
It was no longer, How do I avoid plastic?
It became, Where am I exposing myself to plastic unnecessarily, when there is an easy alternative?
Why Heat Caught My Attention
One of the first things I began noticing was how often we heat plastic and then put whatever has been touching it directly into or onto our bodies.
Research has shown that heat can increase the release of particles and chemicals from some plastics. Once you know that, you start seeing these little combinations everywhere.
Hot coffee is poured into what appears to be a paper cup, although many disposable cups have a thin plastic lining inside. Then we snap on a plastic lid and drink a very hot liquid through it.
At home, I take a different approach with food. I store and reheat leftovers in glass, and I use the air fryer rather than a microwave. It is a simple habit that keeps hot food away from plastic altogether.
None of this means one cup of coffee is going to harm you. I still get coffee to go. But now, if bringing a stainless-steel cup is easy, I bring one. If I’m staying somewhere to drink my coffee, I prefer a ceramic mug.
These are tiny changes, and after a while they don’t feel like changes at all.
Then I started thinking about heat in other parts of my life.
I looked at that little plastic mesh pouf hanging in my shower and realized that every morning I stood under hot water and scrubbed my skin with plastic. I had done it for years without ever thinking about what the thing was actually made of.
When it needed replacing, I bought a natural sea sponge instead.
And I love it. It exfoliates beautifully, but I also simply enjoy using it. There is something wonderful about bringing a little piece of the ocean into the shower rather than another manufactured plastic object.
Once You Notice It, You See Plastic Differently
Clothing was another surprise for me.
Polyester and nylon sound like fabrics, but they are synthetic polymers—in other words, forms of plastic. This is particularly relevant with athletic clothing because so much of what we wear to exercise is made from synthetic fibers.
We know these fabrics shed microscopic plastic fibers during wear and washing. What we don’t know well enough yet is how much microplastic may actually enter the body through the skin, even when the body is warm and perspiring, so I don’t think the science supports telling everyone to throw away their leggings.
It does make me think differently when I am buying something new.
If I’m choosing pajamas, a shirt, bedding or something that will sit against my skin for many hours, I find myself looking more often at cotton, linen, wool and other natural fibers. Not every item can or should be replaced with a natural material, and even natural textiles have their own environmental considerations. The goal isn’t purity. It is simply being more aware of what we’re choosing.
The kitchen offers the same opportunities. Plastic cutting boards can shed tiny particles as knives repeatedly cut into their surfaces. Plastic storage containers eventually become scratched and worn. Disposable water bottles spend hours sitting in cars, garages and warehouses where temperatures fluctuate.
There are perfectly practical alternatives—wood, glass, stainless steel—and I have gradually started choosing those when something needs replacing.
I Don’t Think We Need Another Thing to Be Afraid Of
The difficult part about learning any of this is that once you start looking around, plastic is almost impossible not to see.
It’s in our homes, cars, clothes, food packaging, medical supplies and electronics. Trying to create a completely plastic-free life would be unrealistic for most of us, and I’m not convinced that turning our homes upside down in pursuit of one more version of perfect health would be particularly healthy either.
What feels much more reasonable to me is making smart swaps as life gives us the opportunity.
Use the containers you already own. When they wear out, perhaps replace a few with glass.
When the old cutting board finally needs to go, consider wood.
When you’re buying another water bottle, look at stainless steel or glass.
When your shower pouf falls apart, maybe the next one comes from the sea instead of a factory.
Over time, those decisions begin to add up without requiring a dramatic overhaul of your life.
A Few Things to Think About
For the next week, don’t change anything. Just notice.
Notice where hot food or drinks regularly meet plastic.
Notice what you drink from throughout the day and where that bottle has been sitting.
Look at the things that spend hours against your skin.
Notice which plastic items in your home are scratched, worn or already nearing the end of their useful life.
And then, when one of those things eventually needs replacing, ask yourself a very simple question:
Is there another material that would work just as well?
That is really where I have landed with all of this.
We are still learning what lifelong exposure to micro- and nanoplastics means for human health, and science will undoubtedly give us much better answers in the years ahead. What we already know about plastic particles and some plastic-associated chemicals gives us a reasonable basis to reduce exposures when doing so is simple.
Not because we should be frightened of the world around us.
Because once we know a little more, we can make choices with a little more intention.
And sometimes taking better care of ourselves looks exactly like that—not changing everything, but quietly changing the things that are easy to change.
