Microplastics pose a danger to the heart. While there is enough evidence to show that they clog arteries and exacerbate the risk of stroke, recent research has found that these teeny particles of plastic can trigger cardiovascular diseases. It is estimated that chemicals in plastic were linked to nearly 350,000 heart disease deaths across the world in 2018. Adding to that, is this study published in the journal eBioMedicine, which estimated that roughly 13 per cent of cardiovascular deaths among 55- to 64-year-olds worldwide that year could be attributed to phthalates.Where Are Phthalates are esters of phthalic acids, which are added to plastics to increase their flexibility, transparency, durability, and longevity. They are found in personal care products like shampoos and lotions as well as in food containers and packaging. It is also possible to injest them through food, absorb them through skin from products containing them or breathe them from dust. Some studies have shown an association between phthalates and cardiovascular disease, but there isn’t strong evidence to show that the chemicals directly cause heart issues, said Sung Kyun Park, a professor of epidemiology and environmental sciences at the University of Michigan School of Public Health. However, there is enough evidence that states that phthalates increase the risk of metabolic disorders like obesity and Type 2 diabetes, which can cause cardiovascular disease. One way phthalates may do this is by increasing oxidative stress—cell and tissue damage that happens when there are too many unstable molecules in the body—and by promoting inflammation.Microplastics: Explained Microplastics are extremely small particles—often less than five millimetres in size—created when larger pieces of plastic break down. They can enter the human body in multiple ways: through the air we breathe, the food we eat, and even skin contact. An even smaller subset, known as nanoplastics, measures under 1,000 nanometers and is completely invisible to the naked eye. Because of their minuscule size, these particles can infiltrate tissues, organs, and potentially disrupt biological functions. One Simple Way To Mitigate Risk Of MicroplasticsAmid growing concerns about microplastic contamination, especially in drinking water, scientists have been working on practical ways to mitigate exposure. In 2024, a research team from Guangzhou Medical Centre made a breakthrough. They discovered that a common household activity—boiling water—can significantly reduce microplastic content in tap water.According to the team, combining boiling with basic filtration can remove up to 90% of nanoplastic and microplastic particles (NMPs) from household water. However, the method’s effectiveness varied depending on the type of water used. In areas where tap water contains higher mineral content, commonly referred to as "hard water," the technique proved especially efficient.The secret lies in limescale. As hard water is heated, it forms limescale—a chalky white substance—which appears to create a sticky layer that traps microplastic fragments. Researchers found this natural process enhanced the removal of plastic particles from water, offering a practical and affordable solution for most households.While more research is needed to fully understand the long-term health effects of microplastics, early evidence suggests they may be more dangerous than previously thought—especially for cardiovascular health.
