A new study indicates that middle-aged men may experience faster biological aging due to exposure to "forever chemicals." These synthetic compounds, known as PFAS, are prevalent in many consumer products and resist breakdown, leading to accumulation in the environment and the human body.
Researchers analyzed blood samples and used DNA-based "epigenetic clocks" to estimate biological age. They found that higher concentrations of two specific PFAS compounds, PFNA and PFOSA, were associated with accelerated aging in men aged 50 to 64, but not in women. The study notes that midlife may be a more sensitive biological period, making individuals more vulnerable to age-related stressors and environmental pollutants.
While the findings suggest a link, they do not prove causality. Experts recommend reducing exposure by checking water reports, using certified filters, and limiting the use of stain- or grease-resistant products. Broader regulatory action and environmental cleanup are considered crucial for significant reductions in PFAS exposure.
