In recent years, microplastics—tiny plastic particles less than 5 millimeters in size—have become a growing concern as they’ve been detected in the air we breathe, the water we drink, and the food we eat. For parents, it’s especially concerning to think that microplastics may be impacting our children’s health and well-being in ways we’re only beginning to understand.
What Are Microplastics and Where Do They Come From?
Microplastics originate from larger plastic products that degrade over time due to exposure to sunlight, water, and other environmental factors. They are also intentionally added to products like cosmetics and certain cleaning products. These tiny particles end up in our water, soil, and even the air, making it nearly impossible to avoid exposure entirely.
Children may be especially vulnerable to microplastic exposure because of their unique behaviors, such as playing on the floor and putting objects in their mouths. Additionally, children breathe faster than adults, meaning they may inhale more airborne microplastics. Since their bodies are still developing, they could be more susceptible to any potential harmful effects of these particles.
Potential Health Risks of Microplastics
Research into the effects of microplastics on human health is still in its early stages, but preliminary studies indicate that microplastics could pose risks to children’s health in several ways:
Chemical Exposure: Microplastics often contain harmful chemicals like phthalates, bisphenols (like BPA), and heavy metals. These chemicals have been linked to endocrine disruption, which may interfere with hormones and potentially affect growth, development, and behavior in children.
Inflammatory Responses: When inhaled or ingested, microplastics can trigger inflammatory responses in the body, which could potentially lead to respiratory issues, digestive problems, or other chronic health conditions over time.
Long-Term Health Effects: Since microplastics are new to the environment, the long-term impact of consistent exposure is unknown. However, scientists are increasingly concerned that ongoing exposure to plastics may have cumulative effects on children’s health that could manifest later in life.
Practical Tips for Reducing Microplastic Exposure
While it’s difficult to eliminate all exposure to microplastics, there are some practical steps you can take to reduce your child’s risk:
Limit Plastic Use in Food and Drink: Avoid plastic food containers, especially when heating food. Instead, use glass, stainless steel, or ceramic containers. For school lunches and snacks, consider using reusable silicone bags instead of single-use plastic bags.
Encourage Filtered Water: Tap water and bottled water can both contain microplastics. Consider using a high-quality water filter at home that’s designed to reduce microplastics, or choose glass or stainless steel water bottles over plastic bottles.
Reduce Processed Foods: Packaged foods are often wrapped in plastic, which can lead to indirect ingestion of microplastics. Focusing on fresh, whole foods can help reduce exposure.
Be Mindful of Dust and Clean Regularly: Microplastics can accumulate in household dust. Regular vacuuming with a HEPA filter and wet dusting can help reduce airborne particles. Ensure play areas are kept clean to minimize exposure for children, especially infants who may be crawling or playing on the floor.
Choose Natural Fibers: Many synthetic fibers like polyester and nylon release microplastics when they break down. Opt for clothing and household fabrics made from natural materials, like cotton or linen, when possible. Washing synthetic clothes in a microfiber-catching laundry bag can also help capture microplastics before they enter the water supply.
Avoid Plastics in Personal Care Products: Some exfoliating scrubs and toothpaste contain microbeads, which are a type of microplastic. Look for products labeled “microbead-free” and opt for natural ingredients.
By taking small, mindful steps, we can help reduce exposure and promote healthier choices. Pick something to start with and go from there. When it comes to buying a replacement product, be mindful of what you are choosing. Although it’s impossible to remove every source of microplastics, creating a less plastic-reliant lifestyle can set a positive example and support our children’s long-term health.
Be well,
