Microplastics: The Invisible Threat in Our Bodies

Microplastics are now found in human blood, lungs, placentas, and even the brain, raising concerns about their impact on health. Studies suggest these tiny particles may disrupt gut microbes, potentially influencing conditions linked to depression, colorectal cancer, and neurological disorders. Rodent experiments indicate microplastics can accumulate in organs, alter behaviour, and affect key brain proteins associated with dementia and depression.

Humans are exposed to microplastics through food packaging, synthetic clothing, personal care products, and airborne particles. Although precise “safe” levels remain unknown, experts recommend minimizing exposure. Practical steps include avoiding heated plastics, using glass or stainless-steel containers, switching to wooden chopping boards, selecting natural fibres for bedding, and reducing products containing nano- or microplastics. Limiting contact with synthetic textiles and reducing plastic waste at home may also help.

While research is still emerging, cautious reduction of microplastic exposure offers a sensible strategy for protecting long-term health.
