A study published in February 2026 found that midlife women who reported more anxiety about aging tended to show faster epigenetic aging. The finding is an association, not proof that worry causes aging; researchers also point to lifestyle, environmental exposures and social factors as possible influences.
A study of 726 midlife women published in the February 2026 issue of Psychoneuroendocrinology found that women who felt more anxious about getting older tended to show faster epigenetic aging. The finding adds to research into how psychological and lifestyle factors relate to biological aging, but it does not establish that anxiety causes the changes.
The research measured epigenetic aging, which refers to changes in how genes are switched on and off. The Seniors Guide report, citing Harvard Health editor Maureen Salamon, describes the women with greater anxiety about aging as showing signs of being older at a cellular level. The report does not provide the study’s methods, effect size or details about how participants were selected, limiting what can be concluded from the summary.
The report distinguishes chronological age, the number of years since birth, from biological age, an estimate of how the body is functioning. Measures such as physical fitness, blood pressure and cholesterol can inform estimates of biological age; epigenetic measures offer another way to study age-related changes. These measures are not interchangeable, and the article does not say that the study assessed participants’ overall health or future lifespan.
Other factors discussed include sun exposure, smoking, chronic stress, poor sleep, inactivity and obesity. The report also lists alcohol use, excess radiation, pollution, shift work, loneliness and gut microbiome imbalance. These factors vary in the kind and strength of evidence behind them; the article does not present them as findings from the study of 726 women.
How Aging Anxiety Fits the Evidence
The study draws attention to a possible link between how people feel about aging and biological measures associated with it. That may matter to researchers studying the relationship between mental health and physical health. For readers, the practical point is narrower: an association does not show cause and effect, and the report provides no evidence that worrying about age alone will speed a person’s aging.
The broader list of possible influences also shows why aging is difficult to reduce to one cause. Genes, health conditions, behavior and environmental exposures may all play a part. David Sinclair, a Harvard Medical School professor of genetics quoted in the report, argues that lifestyle affects biological aging. His framing is an expert interpretation, not a result established by the women’s study.
Healthy habits such as regular activity, good sleep, a plant-forward diet and social connection are discussed as ways to support health as people age. The report does not establish that any single habit will reverse epigenetic aging or produce a fixed number of added healthy years.
Biological Age Beyond Birthdays
Chronological age is straightforward to calculate, while biological age is estimated using indicators of bodily function and health. Researchers use epigenetic changes to examine one part of that picture. A finding on an epigenetic measure does not, by itself, show that someone will develop illness or age faster in every sense.
The report summarizes the Information Theory of Aging, a framework Sinclair developed to explain aging through declining ability to read genetic information accurately. He describes the body as a system whose biological information can become corrupted. This is a proposed explanation for aging, rather than a consensus proven by the study described here.
The article also reports Sinclair’s view that genes may account for up to half of differences in how people age, with lifestyle contributing to the rest. That estimate is attributed to Sinclair; the source summary does not give the underlying evidence or explain how the share was calculated.
“There’s a big difference between your birthdays and your biological age — and only the latter can be changed.”
— David Sinclair, Harvard Medical School professor of genetics, as quoted in the Seniors Guide report
What the Study Cannot Establish
The report does not say whether the study followed participants over time or whether researchers accounted for other factors that might affect both anxiety and epigenetic measures. It also omits the size of the observed association and how the researchers measured anxiety. Those details are needed to judge the finding’s scale and limits.
It remains unclear whether anxiety about aging contributes to epigenetic change, whether other circumstances influence both, or whether the association reflects a combination of factors. The result concerns the women studied and should not be treated as a prediction for every person. The report also gives no basis for diagnosing someone’s biological age from their feelings about aging.
Further Research on Aging Anxiety
Further studies would need to clarify how anxiety and epigenetic measures relate over time, account for other relevant influences, and test whether the observed association holds in different groups. The Seniors Guide report does not describe a planned follow-up study or a next research milestone.
For now, the finding is one piece of evidence in a wider area of research. The report points readers toward established health habits, including exercise, consistent sleep, a nutritious diet and strong social ties, while the study itself does not test these steps as treatments for anxiety-related epigenetic aging.
Key Questions
What did the study find?
It found that women reporting more anxiety about aging tended to show faster epigenetic aging, according to the report. It does not show that anxiety caused the changes.
How many people took part?
The report says the study involved 726 midlife women. It does not give further details about participant selection in the summary.
What is epigenetic aging?
It refers to age-related changes in how genes are switched on and off. It is one measure researchers use to study biological aging, not a direct measure of a person’s lifespan.
Can lifestyle changes slow aging?
The report cites research supporting habits such as regular exercise, quality sleep, a plant-forward diet and social connection. It does not promise that these steps will reverse epigenetic aging or produce a specific result.
