A groundbreaking study has revealed that the plastic we use daily could disrupt our sleep, just like caffeine.
Researchers from the Norwegian University of Science and Technology (NTNU) recently published their findings in Environment International. They discovered that certain chemicals released from plastics can interfere with the body’s internal clock, also known as the circadian rhythm. This disruption doesn’t just affect sleep quality—it could also raise the risk of long-term health issues like diabetes and immune system disorders.
In their lab experiments, the researchers exposed human cells to chemicals extracted from two common plastics: PVC (polyvinyl chloride) and PU (polyurethane).
These materials were sourced from everyday items such as medical feeding tubes, hydration pouches, flooring, raincoats, toys, spandex leggings, swimwear, and underwear.
The results were eye-opening. The chemicals were found to interfere with adenosine receptors in our cells. These receptors play a crucial role in regulating sleep-wake cycles. Think of adenosine as your body’s natural signal telling you when to wind down and sleep.
But the plastic chemicals act like that friend who keeps hitting the snooze button—they confuse your body’s natural rhythm and throw your internal clock off balance.
As caffeine blocks adenosine’s “time to sleep” signal to keep us awake, these plastic chemicals may have a similar effect. The difference? We’re exposed to them constantly, so that the impact could last much longer.
Dr. Martin Wagner, who led the study, promptly warned about the potential dangers of certain chemicals found in plastics. He emphasized that these substances can impact human cells more rapidly than natural hormones, suggesting that the issue extends far beyond plastic waste. Wagner underscored the importance of recognizing how environmental chemicals may disrupt the body’s finely tuned 24-hour biological clock, calling it a serious public health concern.
Sleep isn’t just about beauty rest. It’s when your body repairs itself, strengthens the immune system, and maintains mental health. A disrupted body clock can lead to chronic illnesses, inflammation, and metabolic problems. If you’re already living with conditions like diabetes or depression, the effects could be even more serious.
Before you panic and toss every piece of plastic in your home, remember this research is still in the early stages. More studies are needed to understand how much plastic exposure impacts our bodies in daily life. Still, this isn’t the first time science has raised concerns about the hidden dangers of plastic.
Experts recommend being more mindful of your products, especially those that come into close contact with your skin or food. Try to choose items made with safer materials, and avoid microwaving or reusing plastic containers unless they’re microwave-safe.
Plastic is everywhere, and we’re exposed to it more than we realize. But just like cutting back on coffee can help you sleep better, reducing your exposure to plastic, especially certain types, might make a big difference in the long run.
