A study published in February 2026 found that midlife women reporting more anxiety about aging tended to show faster epigenetic aging. The finding is an association, and the report also describes lifestyle and environmental factors linked to aging; it does not establish that worry causes faster aging or that any single change can reverse it.
A study of 726 midlife women, published in the February 2026 issue of Psychoneuroendocrinology, found that participants who felt more anxious about getting older tended to show faster epigenetic aging. The finding adds to research on how psychological and lifestyle factors relate to biological aging, but it does not establish that anxiety causes those cellular changes.
The research measured epigenetic aging, which concerns changes in how genes are switched on and off. The report says women with greater anxiety about aging, particularly fears about declining health, tended to have markers associated with faster aging at a cellular level. The supplied account does not identify the specific measurements, the size of the association, or whether the study followed participants over time.
The report distinguishes chronological age, the time since birth, from biological age, an estimate of how the body is functioning. Measures such as physical fitness, blood pressure and cholesterol can contribute to assessments of biological age. These measures and epigenetic markers describe different aspects of health; the article does not say that one study measurement captures a person’s overall aging or future health.
Other factors discussed include ultraviolet exposure, smoking, chronic stress, poor sleep, inactivity and obesity. The report also names frequent alcohol use, excess radiation, air pollution, shift work, social isolation and gut microbiome imbalance. It presents these as factors associated with aging or possible contributors, with evidence varying by factor. For yo-yo dieting, the report specifically says direct evidence is lacking and describes faster epigenetic change as a theoretical possibility.
Anxiety Joins the Aging Research
The study draws attention to a possible relationship between fear of aging and cellular aging markers. That could matter to researchers studying how mental health, stress and physical health interact across midlife. It does not show that worrying about age itself speeds aging, nor does it establish that treating anxiety would change epigenetic age.
The wider list of factors matters because it spans habits, surroundings and social life. The report describes exercise, consistent sleep, a plant-forward diet, social connections, a positive outlook and a sense of purpose as measures supported by research on healthy aging. These are broad recommendations in the source account, not proof that any one measure will slow aging for every person.
David Sinclair, a Harvard Medical School genetics professor and co-director of its Paul F. Glenn Center for the Biology of Aging Research, estimates that genes account for up to 50% of how slowly or quickly people age. The report attributes the other half to factors people may influence. That estimate is Sinclair’s account, and the supplied material does not detail how it was calculated.

Biological Age Beyond Birthdays
Chronological age is straightforward: it counts years since birth. Biological age is an estimate based on aspects of bodily function and health. Researchers use different measures to study it, including physical indicators and epigenetic markers. These approaches can inform research, but the supplied report does not describe a single standard test that gives a definitive biological age.
Sinclair’s Information Theory of Aging proposes that aging involves a decline in how effectively the body reads genetic information. He characterizes the process as damage to biological “software.” This is his explanatory framework, as presented in the report, rather than a conclusion established by the study of 726 women.
The Seniors Guide article, which credits Maureen Salamon of Harvard Health and says it was distributed by Tribune Content Agency, combines the study with a broader discussion of aging research. Its practical suggestions and the study finding have different evidentiary status: the reported association concerns anxiety and epigenetic markers, while the other factors draw on research described in the article without detailed study citations.
““There’s a big difference between your birthdays and your biological age — and only the latter can be changed,””
— David Sinclair, Harvard Medical School genetics professor
What the Study Cannot Establish
The reported result is an association: participants with more anxiety about aging tended to show faster epigenetic aging. The available account does not establish cause and effect. It also does not provide the study’s methods, the strength of the association, participant demographics beyond midlife women, or evidence that the result applies to other groups.
It remains unclear whether anxiety preceded the measured differences, whether other factors could help explain the association, and how the findings relate to later health outcomes. The report does not say whether reducing anxiety changes epigenetic aging. It also gives no comparison baseline for Sinclair’s statement that people who follow several healthy-aging practices can differ by “sometimes a decade” in biological aging; that figure should not be read as a guaranteed result.
Further Research on Aging Anxiety
Further research would need to clarify how anxiety and epigenetic aging are connected, including whether the relationship persists over time and what other influences may be involved. Studies that report their methods, measures and comparison groups would help readers assess the strength and reach of the finding.
The supplied report does not identify a planned follow-up study or a specific next research milestone. For now, it presents the result as one finding within a broader field examining biological aging. It describes regular exercise, quality sleep, a plant-forward diet and strong social connections as general healthy-aging measures, while the effects of any one measure on an individual’s biological age remain uncertain.
Key Questions
What did the study find?
In a study of 726 midlife women, greater anxiety about aging was associated with faster epigenetic aging. The reported finding does not establish that anxiety caused the difference.
What is epigenetic aging?
It refers to age-related patterns in how genes are switched on and off. Researchers use epigenetic measures to study biological aging; they are distinct from chronological age.
Does worry about aging cause the body to age faster?
The report describes an association, not proof of cause and effect. It does not show whether reducing anxiety changes epigenetic aging.
Which factors does the report link with faster aging?
It discusses factors including UV exposure, smoking, chronic stress, poor sleep, inactivity and obesity, along with environmental and social factors. The evidence described varies, and the report says direct evidence for yo-yo dieting is lacking.
What does the report say may support healthy aging?
It cites regular exercise, consistent high-quality sleep, a plant-forward diet and strong social connections, along with a positive outlook and sense of purpose. The report does not promise that these measures will change any one person’s biological age.
