Are Plastic Water Bottles Safe for Children? What You Need to Know
As temperatures rise, keeping your family hydrated becomes more important than ever. You may have already gotten your child into the habit of carrying a reusable water bottle to school, camp, or extracurricular activities, but sometimes, the convenience of plastic water bottles wins out. You walk into a coffee shop, your child suddenly feels parched, and you end up buying a plastic bottle. We understand the temptation. However, before you make a habit of using plastic water bottles, it’s important to understand the potential risks, especially during warmer weather.
Understanding the Risks of Plastic Water Bottles for Your Health
Plastic water bottles are ubiquitous in our daily lives. We’ve all seen them littering parks, beaches, and streets alongside other plastic bags, food containers, and single-use plastic bottles. According to Statistics Canada, in 2019, nearly 6,000 tons of plastic bottles ended up in the environment as part of the 43,000 tons of plastic waste that was released.
What’s not as visible is the potential harm the water inside single-use plastic bottles can cause. Research has shown that over time, plastics break down into smaller particles, known as microplastics, which can further degrade into even smaller particles called nanoparticles—less than 1 micrometer in size. These particles are small enough to penetrate human cells and tissues. Microplastics have been found in human blood, lungs, and reproductive organs.
Another invisible issue with single-use plastic bottles is the presence of harmful chemicals. According to the Health and Environment Alliance (HEAL), the production of plastics often involves dangerous chemicals like heavy metals and Bisphenol A (BPA), both of which pose health risks.
What Happens to Plastic Water Bottles When They Heat Up?
Whether it’s leaving a plastic water bottle in the car on a hot day, sitting it on a sunny picnic table at the park, or simply carrying it around during a summer walk, higher temperatures can cause the chemicals in the plastic to leach into the water more rapidly than at room temperature or cooler conditions.
Dr. Jenna Wheeler, a pediatric ICU physician at the Arnold Palmer Hospital for Children in Orlando, warns that plastic water bottles should be discarded after 12 hours of sun exposure. She also emphasizes that single-use bottles should not be reused. “Single-use water bottles should be filled with water, used, and then either thrown away or recycled,” she explains.
Health Risks of Drinking from Plastic Bottles
Drinking from plastic bottles, especially after they’ve been exposed to heat, can pose several health risks. Studies suggest that heavy metals present in single-use plastic bottles are endocrine disruptors, meaning they interfere with the body’s hormone systems. Endocrine disruption can increase the risk of cancer and reproductive issues.
Wheeler stresses that exposure to plastic chemicals can impact children’s development. “It’s hard to pinpoint exactly what effect these chemicals will have on each child, but we do know that globally, these chemicals affect the development of all organs,” she says.
While research on the effects of consuming microplastics is still limited, existing studies suggest that they may disrupt reproductive health in a manner similar to heavy metals and other chemicals.
Stay Hydrated, But Choose Reusable Water Bottles
We understand that carrying a reusable water bottle isn’t always practical. However, Wheeler emphasizes the importance of staying hydrated, even if it means using a plastic bottle, especially in hot summer weather. “I’d rather see someone drinking from a plastic water bottle in the sun than not hydrating because they don’t have a stainless steel bottle,” she says.
Ultimately, while using plastic water bottles occasionally may be unavoidable, it’s important to prioritize long-term health by choosing safer, reusable alternatives like stainless steel or glass bottles when possible. Encouraging your family to make this switch will not only reduce exposure to harmful chemicals but also help in reducing environmental waste.
Stay hydrated, but make mindful choices to protect your family’s health.
