Why Your Organs Wear Out Prematurely: How to Fix It

Are you sure your heart, liver or brain correspond to your passport age?
New research shows that organ aging may be accelerated by lifestyle, genetics or random factors.
Scientists at Stanford University have proven that even in genetically identical mice, organs age at different rates.
Some rodents remained active and clear-minded until old age, while others lost their health by midlife.
Why do some people age faster?
In 2020, scientists led by Stanford's Tony Weiss-Coray studied 17 organs in laboratory mice.
It turned out that the rate of aging of different tissues in one organism can differ.
During the study, it was discovered that 20% of the participants in the experiment had at least one organ that was 10–15 years “older” than their chronological age.
Risks that cannot be ignored
People with an "aged" heart had a 250% higher risk of heart failure, and those with a faster-aging brain were 3.4 times more likely to develop Alzheimer's disease.
Scientists confirm that even one “old” organ increased the risk of death by 20–50%.
Brain aging is a key driver of mortality, said Hamilton Se-Hwi Oh, lead author of the Stanford study.
How to slow down organ aging
Lifestyle directly influences age types.
Study participants who smoked, drank alcohol heavily, or ate processed meat accelerated organ aging by 3 to 7 years.
Those who exercised 150 minutes a week and included fatty fish in their diet kept their organs “younger” by 4–5 years.
We can't change genes, but we can influence 70% of the factors that cause aging, says Thomas Rando, director of the University of California Stem Cell Research Center.
Scientists recommend strength training, which renews muscle cells at the molecular level.
The Mediterranean diet also reduces inflammation, which accelerates aging.
It is useful to give up ultra-processed foods. They accelerate intestinal aging by 5 years.
Moreover, 30 minutes of walking a day reduces heart age by 3 years.
The most important thing is to act now. Even small lifestyle changes can “rejuvenate” your organs by years, concludes Hamilton O.
