What Are Microplastics and Why Should You Care?
Microplastics are tiny plastic particles that are typically less than 5 millimetres in size. They can be found everywhere – in our food and water sources, the air we breathe, and more recently within our bodies. Given how widespread they are, people naturally want to know how they may affect their health.
Most of us know that plastic negatively impacts our environment because of the time required to break down these materials. But what about their impact on human health? Scientists are now finding microplastics in humans – within our organs, bloodstream, brains, and even in unborn babies. While research is still ongoing, there is growing evidence that these particles may pose real health risks.
How Do Microplastics Enter the Body?
Since microplastics are so small, it is not possible to see them or avoid them entirely. Some of the common ways people are exposed to microplastics include:
- Drinking water – particles can be found in both bottled and tap water
- Eating seafood – fish and shellfish ingest microplastics from polluted waters, and these particles are passed on to those that consume them
- Breathing – microplastics are present in our air with synthetic fabrics and household dust being common sources
- Plastic containers – storage and heating containers are a primary source of plastic contamination in food and beverages
- Common household products – items such as like tea bags, plastic cutting boards, and personal care products can release microplastics
The Potential Health Risks of Microplastics
Researchers are still trying to fully understand the effects of microplastics on human health, but early findings suggest alarming risks:
1. Inflammation and Organ Damage
Once inside the body, microplastics do not break down easily. Instead, they may build up in organs, triggering inflammation and long-term damage. Studies on animals show that ingesting microplastics can cause digestive issues, gut inflammation, and liver damage.
2. Heart Health
A recent study found a link between microplastics and an increased risk of heart attack and stroke. Microplastics were found in the arteries of patients with heart disease, and those with higher levels were twice as likely to suffer a major cardiovascular event.
3. Hormone Disruption and Fertility Issues
Many plastics contain chemicals like Bisphenol A (BPA) and phthalates, which can act as endocrine disruptors. These chemicals interfere with hormone levels and have been linked to:
- Lower fertility in men and women
- Changes in testosterone and estrogen levels
- Increased risk of reproductive disorders
4. Pregnancy Risks
Scientists have now detected microplastics in unborn babies. raising serious concerns about their impact on fetal development. Early research suggests microplastics could lead to low birth weight, premature birth, and potential developmental problems.
5. Effects on the Immune System
Recent studies indicate that microplastics may also weaken the immune system, making it harder for the body to naturally fight infections. Some research suggests microplastics may also contribute to the development of autoimmune diseases by causing long-term inflammation.
Reducing Your Exposure to Microplastics
While it is nearly impossible to avoid microplastics completely, there are simple steps you can take to reduce your exposure:
- Drink filtered water – use a high-quality water filter that can remove microplastic particles
- Avoid plastic bottles and containers – opt for glass or stainless steel instead
- Use natural fabrics – choose clothing and household items made from cotton, wool, or other natural fibres rather than synthetic materials
- Limit processed foods – microplastics can be found in packaged and processed foods. Fresh, whole foods are a safer and healthier choice
- Choose tea carefully – some commercial tea bags release millions of microplastics into your tea. Switch to loose-leaf tea or brands that use plastic-free coverings
- Reduce plastic use – simple swaps like reusable shopping bags, glass food storage containers, and bamboo utensils might seem small but collectively, they can make a difference
More Research and Action
Governments around the world are beginning to take action against microplastic pollution, but more research is needed to fully understand their long-term health risks. Scientists are continuing to study how microplastics move through the body and what steps can be taken to minimize harm.
In the meantime, being aware of the health risks of microplastics and making small changes in your daily routine can help reduce your exposure.
