Microplastics are tiny plastic particles—typically less than 5 millimetres in size—that originate from the breakdown of larger plastic items or from manufactured sources such as synthetic clothing fibres, cosmetics, and packaging. These particles are now found almost everywhere, including in water, soil, air, and even within the human body. Emerging research suggests that microplastics may contribute to inflammation, oxidative stress, and potential disruption of hormonal systems, although long-term health effects are still being investigated. For individuals focused on long-term wellness, reducing exposure—by limiting plastic food storage, avoiding heating food in plastic, and choosing filtered water—can be a practical step toward lowering overall toxic load.
