Key Takeaways
- Perimenopause is associated with changes in biological ageing markers, but it does not mean you are destined to age faster or less healthily.
- Declining oestrogen levels can influence skin, muscle, bone, metabolism and cardiovascular health, making this a pivotal time to support healthy ageing habits.
- Research shows that lifestyle factors such as physical activity, sleep quality and metabolic health can have a powerful influence on how you age during and after perimenopause.
Did you know that scientists can now estimate your “biological age” by measuring chemical markers on your DNA? Even more fascinating, research suggests that the menopausal transition may influence these ageing markers independently of your chronological age.
This discovery has sparked an important question: does perimenopause actually accelerate ageing, or is it simply another chapter in the body’s natural evolution? The answer is more nuanced—and much more positive—than many headlines suggest.
Understanding Perimenopause and Biological Ageing
Before exploring the science, it helps to understand what researchers mean by “ageing”. Chronological age is simply the number of birthdays you’ve celebrated. Biological age, however, reflects how well your cells, tissues and organs are functioning. Scientists often measure biological ageing using epigenetic clocks, which assess changes in DNA methylation patterns associated with ageing.
Perimenopause is the transitional stage leading up to menopause. During this time, ovarian hormone production becomes less predictable, and oestrogen levels can fluctuate significantly before eventually declining. Recent large-scale research found that women in perimenopause and postmenopause showed greater biological age acceleration compared with premenopausal women, suggesting that reproductive ageing and biological ageing are closely linked (R).
Importantly, this does not mean that perimenopause causes rapid deterioration. Instead, it highlights that the menopausal transition is a period of significant biological adaptation.
Why Oestrogen Plays Such an Important Role in Healthy Ageing
One reason researchers are interested in perimenopause and ageing is that oestrogen affects nearly every major system in the body. Oestrogen helps regulate inflammation, supports blood vessel function, influences glucose metabolism and contributes to mitochondrial energy production. Mitochondria are often called the “powerhouses” of cells because they generate the energy needed for cellular function.
As oestrogen levels decline, several physiological systems must adapt. Research has shown that post-menopausal declines in oestrogen are associated with increased inflammatory markers, altered mitochondrial bioenergetics, and reduced antioxidant capacity, all of which are linked to biological ageing processes (R).
This may sound concerning, but it is worth remembering that ageing is influenced by many factors. Hormones are just one piece of a much larger puzzle that includes genetics, physical activity, nutrition, sleep and environmental exposures.
The Surprising Connection Between Perimenopause and Epigenetic Age
One of the most fascinating discoveries in ageing science emerged from a landmark study examining epigenetic ageing. Researchers found that menopause was associated with accelerated epigenetic ageing in blood cells. They also observed that women who experienced earlier menopause tended to show greater biological age acceleration (R).
This finding has since been supported by additional studies showing associations between menopausal status and biological ageing markers (R). However, there is an important nuance. Some scientists argue that menopause may not be the sole driver of ageing. Instead, ageing itself may contribute to ovarian ageing and the eventual onset of menopause. In other words, the relationship appears to work in both directions (R). This highlights an encouraging reality: ageing is a complex biological process rather than a simple consequence of hormonal change.
Your Skin’s Natural Renewal Journey During Perimenopause
One of the most visible signs of perimenopause occurs in the skin. Oestrogen supports collagen production, skin hydration and elasticity. As hormone levels change, collagen synthesis slows, and the skin’s structure gradually adapts. A comprehensive review found that declining oestrogen levels contribute to reduced collagen production, lower elasticity, and decreased skin moisture (R).
One particularly surprising fact is that a significant proportion of collagen loss occurs during the menopausal transition itself rather than gradually over many decades. This helps explain why some women notice relatively sudden changes in skin texture or firmness around this stage of life (R).
The encouraging news is that skin remains highly responsive throughout life. Healthy lifestyle habits, sun protection and overall metabolic health continue to support skin quality well beyond menopause.
Heart Health, Metabolism and the Menopausal Transition
While skin changes often receive the most attention, some of the most important adaptations occur beneath the surface. Emerging research involving nearly 9,000 women found that cardiovascular health may begin changing during perimenopause, earlier than previously thought. Women in perimenopause were more likely to have less favourable cholesterol and blood glucose profiles compared with premenopausal women (R).
This occurs partly because oestrogen influences:
- Blood vessel flexibility
- Cholesterol metabolism
- Glucose regulation
- Fat distribution
- Inflammatory pathways
Rather than viewing this as inevitable decline, many experts describe perimenopause as a valuable “window of opportunity” to strengthen long-term health. Improvements in physical activity, sleep, nutrition and cardiovascular fitness during this period can deliver benefits for decades to come (R).
Why Lifestyle Still Has a Powerful Influence on Ageing
Perhaps the most empowering message from ageing research is that biological age is not fixed. Epigenetic age can be influenced by lifestyle factors, and researchers increasingly recognise that healthy behaviours help shape ageing trajectories throughout adulthood. Regular resistance training helps preserve muscle mass and metabolic health. Physical activity supports mitochondrial function and cardiovascular fitness. High-quality sleep supports cellular repair processes and healthy immune function.
Research has even shown that sleep disturbances commonly experienced during menopause are associated with accelerated biological ageing markers, highlighting the importance of prioritising restorative sleep (R). These findings reinforce a positive message: while hormonal changes are unavoidable, many aspects of healthy ageing remain highly modifiable.
The Bottom Line on Perimenopause and Ageing
So, does perimenopause accelerate ageing? The scientific evidence suggests that the menopausal transition is associated with measurable changes in biomarkers of biological ageing and physiological systems. Hormonal changes can influence skin, cardiovascular health, metabolism and cellular ageing pathways (R,R).
However, this is not a story of inevitable decline. Perimenopause is better viewed as a significant biological transition—one that creates an opportunity to support healthy longevity through movement, restorative sleep, stress management and metabolic health. Your biological age is shaped by far more than hormones alone. In many ways, understanding these changes empowers you to take proactive steps that support vitality, resilience and healthy ageing for years to come.
