Study Finds Faster Biological Aging in Millennials and Gen Z

An international study published in *Nature Medicine* analyzed health data from more than 160,000 adults in the United States and the United Kingdom. The researchers reported that people born after the mid‑1990s (or after 1965, according to a related press release) show signs of accelerated biological aging compared with earlier generations. The faster aging was linked to a higher risk of several cancers, including colon and lung tumours.

The authors stress that the findings describe statistical correlations, not a certainty that every individual will age faster or develop cancer. Potential contributors such as excess weight, sedentary lifestyles, poor diet and environmental factors were noted, though no definitive cause was identified. They also suggest that regular exercise, balanced nutrition, adequate sleep and strength training may help mitigate the risk.

The study’s authors hope the results will guide early‑risk detection and personalized preventive strategies, while acknowledging that long‑term follow‑up is required to fully understand the observed trends.
