Is Age Just a Number? Think Again! Science Reveals Mothers Often Age Faster Than Fathers
While a recent Finnish study suggests men may be biologically older than women of the same age, researchers say pregnancy, hormonal changes and caregiving responsibilities can make mothers show visible signs of ageing sooner. Here’s what science says and what women can do to stay healthier for longer.

Pune: Have you ever noticed that many mothers seem to develop wrinkles, grey hair or fatigue earlier than fathers? While it may appear to be just an observation, scientists say there are several biological and lifestyle factors behind it.
Interestingly, recent research from the University of Jyväskylä in Finland found that men are biologically older than women of the same chronological age, with male twins appearing about a year biologically older than their female twins. Researchers linked this partly to smoking, body size and genetic differences. However, women continue to enjoy a longer life expectancy than men in most countries.
At the same time, other studies explain why motherhood itself can accelerate visible ageing.
Pregnancy places enormous demands on the body. Hormonal fluctuations, increased blood volume, weight gain and changes in the immune system make pregnancy one of the most physically demanding phases of a woman’s life. Research suggests each pregnancy may temporarily increase biological age by two to three months, although some of these changes may partially reverse after childbirth.
Childbirth and recovery place additional stress on muscles, joints and the cardiovascular system. Breastfeeding, interrupted sleep and the physical effort of caring for a newborn further increase fatigue during the early years of motherhood.
Stress also plays a major role. Mothers often balance childcare, careers and household responsibilities simultaneously. Chronic stress raises cortisol levels, which over time may contribute to faster biological ageing by affecting cells, skin health and overall wellbeing.
Hormonal changes continue well beyond pregnancy. Fluctuations in estrogen and progesterone, followed by menopause later in life, can affect bone strength, skin elasticity, energy levels and cardiovascular health. These natural changes may make ageing appear more noticeable in women.
Scientists, however, caution against drawing simple conclusions. The Finnish study found that despite women showing some visible ageing related to motherhood, men generally experience faster biological ageing overall, highlighting that ageing is influenced by genetics, lifestyle and environmental factors together rather than gender alone.
Tips to Slow Healthy Ageing
- Prioritise 7–9 hours of quality sleep whenever possible.
- Eat a balanced diet rich in protein, fruits, vegetables and healthy fats.
- Exercise regularly with a mix of walking, strength training and flexibility exercises.
- Manage stress through yoga, meditation or mindfulness.
- Share parenting and household responsibilities to reduce mental and physical exhaustion.
- Stay hydrated and avoid smoking and excessive alcohol consumption.
- Schedule regular health check-ups, especially after pregnancy and during menopause.
- Build a strong support system of family and friends to reduce emotional stress.
Experts say ageing is a natural process, but healthy habits, emotional support and shared caregiving can help both mothers and fathers maintain better physical and mental health throughout life.
