Stress makes life’s clock tick faster, new study finds

-Chronic stress accelerates the body’s epigenetic clock. Those that can manage the effects of stress by strengthening their emotional regulation and self-control can slow the process.

-Psychological and biological resilience modulates the effects of stress on epigenetic aging. Our society is experiencing more stress than ever before.

-Recently developed “epigenetic clocks” such as GrimAge have shown utility in predicting biological age and mortality.

 
Scientists in recent years have developed ways to measure biological age by tracking chemical changes in DNA that occur naturally as people age but occur at different times in different people. These so-called “epigenetic clocks” have proved to be better predictors of lifespan and health than chronological age.

In a new study, Yale researchers used one such clock, appropriately named “GrimAge,” to ask two questions: How much does chronic stress accelerate that biological clock? And are there ways to slow it down and extend a healthy lifespan?

According to their findings, published in the journal Translational Psychiatry, stress does indeed make life’s clock tick faster — but that individuals can help manage the effects by strengthening their emotion regulation and self-control.
