Biological Age

What is Biological Age?

Biological age measures how well your body functions compared to your chronological age (the number of years you've been alive). Unlike chronological age, which advances consistently, biological age considers factors like cellular health, organ function, and your body's ability to handle stress and illness. It provides a more comprehensive view of how your body is ageing internally.

Understanding Biological Age

Two individuals of the same chronological age may have very different biological ages. For example:

• One person might have a body functioning like someone much younger due to healthy lifestyle choices.

• Another might have a body functioning like someone older, potentially due to poor habits, chronic stress, or illness.

Influencing Factors

Biological age is influenced by:

• Lifestyle Choices: Diet, exercise, sleep quality, and substance use.

• Stress Levels: Chronic stress can accelerate biological ageing.

• Genetics: Family history can affect how your body ages.

• Health Conditions: Chronic diseases or conditions can impact cellular and organ health.

Importance of Biological Age

Understanding your biological age helps:

• Track Health: Provides insights into how lifestyle changes affect your overall well-being.

• Motivate Change: Encourages adopting healthier habits to slow ageing and reduce the risk of age-related diseases.

• Personalise Care: Enables tailored approaches to nutrition, fitness, and medical care based on individual ageing profiles.

Latest Research and Legislation

In 2024, advances in biotechnology and diagnostics have made biological age assessments more accessible. These tools are being explored under the Life Sciences Vision 2021 initiative to improve personalised healthcare. Ethical considerations around these technologies are also being discussed under the Genomics and Health Act 2023.
