A new study from researchers at New York University found that higher levels of anxiety about aging, particularly concerns over declining health, correlated with signs of accelerated biological aging in women. The study highlights how chronic stress from psychological experiences can lead to measurable epigenetic changes and impact physical health.

Why it matters

This research builds on a growing body of work in the field of biological aging, underscoring the importance of mental wellbeing alongside physical factors like diet and exercise. It suggests that a positive mindset and proactive approach to managing anxieties about aging can have tangible impacts on long-term health.

The details

The NYU study analyzed data from 726 women with an average age of 50. Participants completed a questionnaire assessing their fears related to aging, including concerns over loss of attractiveness, health issues, and reproductive changes. Blood samples were also analyzed to determine the women's biological age, reflecting the rate of cellular aging and damage. The results showed that higher levels of anxiety, particularly about declining health, correlated with signs of accelerated biological aging. Interestingly, concerns about physical appearance or fertility did not have the same significant impact.

  • The study was published in the journal Psychoneuroendocrinology in March 2026.

What they’re saying

“Women at midlife often juggle multiple roles, including caring for their aging parents. Seeing their loved ones become ill can lead them to wonder if the same thing will happen to them.”

What’s next

The researchers recommend actively addressing fears about aging, prioritizing mental health alongside physical health, and seeking support when needed. Practices like mindfulness, meditation, and therapy can be valuable tools for managing anxiety and cultivating a more positive outlook on aging.

The takeaway

This study highlights how our psychological experiences, particularly chronic stress and anxiety about aging, can have measurable impacts on our physical health and the rate of biological aging. By proactively managing these mental health factors, individuals may be able to positively influence their long-term wellbeing.
