Most people know their chronological age, but doctors emphasize the existence of another indicator that requires attention—biological age. This indicator reflects the condition of vital bodily systems, such as the heart, muscles, and metabolism, rather than just the number on an ID card.
Initiatives in Dubai
The topic of biological aging has gained new momentum after Dubai announced the creation of the Dubai Longevity Authority. This initiative aims to strengthen the emirate's position as a global center for preventive medicine and healthy aging.
Dr. Rola Fayyad, an internal medicine specialist at Burjeel Medical Center in Silicon Oasis, explained: 'Chronological age is simply the number of years lived. Biological age shows how our body truly feels and functions.'
Factors Affecting Aging
According to specialists, a person's biological state depends on numerous factors, including lifestyle, stress levels, sleep, nutrition, and overall health. Dr. Fayyad noted that two people of the same age can age at completely different rates.
Experts confirm that the difference between chronological and biological age can reach ten to twenty years. For example, a healthy 40-year-old may have a biological age corresponding to the early 30s, while another person of the same age with chronic inflammation, poor sleep, or high visceral fat might biologically appear fifty years old.
Assessment Methods and Lifestyle Impact
Appearance can often be deceiving, as a person may look healthy on the outside while hiding internal risks such as early arterial hardening, increased inflammation, or insulin resistance. This is why longevity medicine is gaining popularity—it allows for the detection of signs of aging at early stages and intervention before diseases appear.
Biological age is assessed using a complex set of biomarkers, including blood sugar, cholesterol, inflammation, body composition, muscle mass, and cardiovascular health indicators. Some advanced methods include DNA testing to predict the rate of cellular aging.
Although genetics plays a role, experts believe that daily habits have a huge impact on the pace of aging. Dr. Malathi Arshanapalai, Chief Medical Director and Chief Quality Officer at Aster DM Healthcare, listed chronic stress, lack of sleep, smoking, lack of physical activity, unhealthy diet, and obesity as major accelerators of biological aging.
These factors contribute to increased oxidative stress, inflammation, and metabolic dysfunction, which gradually deteriorates cell health. However, she added that although aging cannot be stopped, its speed can be slowed down by adopting healthier habits.
Improving metabolic health, cardiovascular fitness, muscle strength, and overall resilience is achieved through better nutrition, regular exercise, quality sleep, stress management, and maintaining a healthy weight. Aster's Thrive by myAster program offers an assessment of 100 biomarkers to identify potential risks before symptoms appear.
Doctors advise not to postpone caring for healthy aging, but to start at age 30 or even earlier, as biological aging tends to accelerate around 45 and again around 60. Regular exercise, strength training, quality sleep, a balanced diet, stress management, quitting smoking, and maintaining social connections help people stay healthy longer.
Growing Interest in the UAE
Interest in longevity medicine is growing in the UAE as residents increasingly shift focus from treating diseases to preventing them. Dr. Adnan Ghazi Al-Khalefeh, a cardiologist at NMC Royal Hospital in Mohammed Bin Zayed City, Abu Dhabi, noted that the highest demand is among individuals aged 35 to 60, although younger professionals also undergo screenings due to family history of heart disease, diabetes, or obesity.
He emphasized that muscle strength, grip strength, and cardiovascular fitness are some of the most reliable indicators of healthy aging. According to him, 'longevity is not just living longer; it is extending the number of years spent in good health.'
By focusing on cardiovascular fitness, muscle strength, nutrition, sleep, and preventive screening, one can significantly improve both life expectancy and quality of life. Experts note that sedentary work, stress, and the hot climate of the UAE complicate maintaining activity, but growing awareness and easier access to preventive care encourage residents to take control of their long-term health.
It is believed that the recently established Dubai Longevity Authority could accelerate this transition by promoting early risk assessment, personalized care, and preventive medicine. Vikas Harbanda, Partner and Head of Health and Life Sciences Practice at Arthur D Little Middle East, stated that this authority could attract global talent, investment, and advanced medical technologies, strengthening Dubai's position as a global center for longevity innovation.
