Can household chemical exposure speed up how fast your body ages?
Possibly. A 2025 machine learning study found that environmental chemical exposure is linked to accelerated biological aging in humans.
What's actually in it
Your body is exposed to hundreds of chemicals daily from food packaging, cleaning products, personal care items, and indoor air. These include PFAS, phthalates, heavy metals, and pesticide residues. The concept of "biological age" measures how worn out your cells are compared to your calendar age.
What the research says
A 2025 study in Arch Gerontol Geriatr used machine learning to identify which environmental chemicals are most strongly linked to accelerated biological aging. Certain chemicals, including PFAS, heavy metals, and phthalates, were identified as top contributors to faster aging.
Reduce exposure by choosing glass food storage, filtering water, and using fragrance-free cleaning and personal care products.
