If you’ve ever gone through a stressful period of life, only to think how much older you looked on the other side, you may relate to the findings of a new study.
If you’ve ever gone through a stressful period of life, only to think how much older you looked on the other side, you may relate to the findings of atoday. But there’s some good news: While the study confirms that stress can have an aging effect, it also shows that recovery can reverse it. The research was a collaboration of a number of schools, including Harvard Medical School and Duke University.
“In the most fundamental sense,” the authors write in the new paper, “our data reveal the dynamic nature of biological age: stress can trigger a rapid increase in biological age, which can be reversed.” The premise of the research is that chronological and biological age aren’t always the same. That is, the body of a 40-year-old who’s lived an extremely healthy life might function more like a 35- or even 30-year-old person . The reverse is true for someone who’s led a less-healthy life.
It's also well known that stress can have an aging effect on the body in measurable ways – the question the researchers behind the current study wanted to get at was whether a recovery period after a stressful event could reverse this process. To determine biological age, they used newer iterations of biological age-estimation tools, which generally rely on capturing changes at the epigenetic level . They measured biological age across a range of stressful and sometimes strange situations in mice and humans.
