Chronological age is the number of years a person has been alive, while biological age reflects the physiological state of the body compared to others of the same chronological age 1. 1  

While chronological age is fixed and increases steadily, biological age can vary significantly among individuals. It considers factors like cellular health, organ function, genetics, lifestyle choices, and environmental influences . 1. 2 

Biological age can be influenced and modified through interventions such as adopting a healthy lifestyle, managing stress, and engaging in regular exercise . 1. 3 

Understanding the difference between these two concepts is important because it emphasizes the impact of lifestyle choices on aging.  

While we can’t control our chronological age, we can take steps to improve our biological age, potentially slowing down the aging process, reducing the risk of age-related diseases, and enhancing our overall well-being. 

A lower biological age is better than a higher one because it indicates that your body is functioning like that of a younger person.  

This means that you are less likely to develop chronic diseases such as heart disease, diabetes, and cancer. 4 

In contrast, a higher biological age indicates that your body is functioning like that of an older person and you may be at higher risk for developing these diseases . 4 

To improve your biological age, you can adopt healthy lifestyle habits such as;  

 

• eating a balanced diet rich in fruits and vegetables 
• getting enough sleep each night 
• exercising regularly 
• managing stress levels through meditation or other relaxation techniques 
• reduce your exposure to environmental toxins such as air pollution and cigarette smoke. 

In conclusion, while we cannot control our chronological age, we can take steps to improve our biological age.  

By adopting healthy lifestyle habits and reducing exposure to environmental toxins we can potentially slow down the aging process and reduce the risk of developing chronic diseases.  

A lower biological age is better than a higher one because it indicates that your body is functioning like that of a younger person.
