Your date of birth does not change; you grow one year older every year. Yet two people born in the same year can differ greatly in energy, movement capacity and health. This difference is the focus of the concept of biological age.
Chronological and biological age
Chronological age is the age the calendar tells us. Biological age is an estimate of how much wear our cells, tissues and organs have undergone. Our lifestyle greatly influences the gap between the two.
How is it estimated?
There is no single, definitive test that measures biological age. Epigenetic tests, telomere length and various laboratory parameters offer different windows on it. Each gains meaning not on its own but when assessed together.
Can it be changed?
A growing body of research suggests that markers associated with biological age can be influenced by lifestyle factors such as sleep, nutrition, movement, stress management and social connections. This means that each of us has a say in our own biological journey.
