Spending less time on the sofa lengthens “telomeres”-the caps on chromosomes which protect the genetic code inside.
The best anti-ageing technique could be standing up, scientists believe, after discovering that spending more time on two feet protects DNA.
A study found that too much sitting down shortens telomeres, the protective caps which sit at the end of chromosomes.
Short telomeres have been linked to premature ageing, disease and early death. So spending less time on the sofa could help people live longer by preventing their DNA from ageing.
The research found that people who were frequently on their feet had longer telomeres, which were keeping the genetic code safe from wear and tear.
