A person’s age can be measured according to two different parameters: chronological age and biological age. The former expresses the time elapsed since birth (e.g. 45 years), while the latter evaluates the person’s state of health in relation to the average population of the same chronological age. Biological age can be influenced by various factors, including:
- Genetics: e.g. congenital alterations of lipid metabolism
- Environmental factors: e.g. excessive UV exposure accelerates skin ageing
- Lifestyle: nutrition, exercise, quantity and quality of sleep etc.
A healthy lifestyle helps slow down the ageing process.
