DNA damage theory

The DNA damage theory suggests that over time, our DNA—the genetic material inside our cells—accumulates changes or injuries caused by factors like radiation, pollution, or normal metabolic processes. These damages can disrupt cell functions, leading to aging and an increased risk of diseases such as cancer. The body has repair systems to fix DNA, but as damage piles up with age or exposure, these repairs become less effective, contributing to the aging process and health decline. Essentially, DNA damage is a key driver behind aging and age-related health issues.
