Difficult People in Your Life May Be Aging You Faster, Study Finds
Each additional hassler: roughly nine months of extra biological age
Mark
So what did the study actually find?
Mimi
That people with more hasslers in their lives, meaning people who create problems or make life harder, tend to have a higher biological age than their actual age.
Mark
How big is the effect?
Mimi
Each additional hassler is associated with about 1.5% faster biological aging, roughly nine months of extra biological age.
Luke
I'd keep that word associated in view. The authors say plainly this doesn't prove negative social ties cause faster aging.
Mark
But they controlled for other things, didn't they?
Mimi
Yes: occupation, adverse childhood experiences and smoking. The link stayed significant after that.
Luke
Controlling for three factors helps, but it doesn't cover everything. Someone who is already unwell or stressed might also attract or perceive more hassle. The reporting doesn't say how that was handled.
Mark
What about the spouse finding?
Mimi
Family and friend hasslers showed harmful associations. Spouse hasslers did not.
Luke
And the reporting gives no explanation for that. It's an observed difference, not an explained one.
Mark
What comes next?
Mimi
The authors call for interventions that reduce harmful social exposures, and causal studies would be needed to show whether those would work.
Le Pouls
- A new PNAS study puts a measurable price on difficult relationships, linking each additional 'hassler' to roughly nine months of extra biological age.
- The strongest signal comes from family and friends, while spouses, surprisingly, do not show the same pattern, leaving researchers puzzled.
- The link survives adjustments for occupation, childhood adversity and smoking, yet the study can only show association, not that hasslers cause faster aging.
- Researchers are pressing for causal studies and interventions that reduce harmful social exposures, with the question of whether healthier ties can actually slow aging still open.
A recent study in the Proceedings of the National Academy of Sciences offers a quiet but unsettling observation about everyday life: people surrounded by more individuals who make their lives difficult tend to show bodies that look older than their years. Researchers measured this by comparing each person's birth-certificate age with a biological age that reflects how the body appears to be aging, and they found the gap widened with each added source of friction. The findings fit an old human intuition that stress lingers in the body, though the study shows only a correlation, not a verdict on cause. Scientists now await the more rigorous work that might reveal whether easing such relationships could slow the clock.
A study published last month in the Proceedings of the National Academy of Sciences gives numbers to a suspicion many people already hold: the people who make life harder may also be aging the body faster.
The researchers counted what they call hasslers, people in a person's social circle who create problems or make daily life more difficult. They compared these counts with each person's chronological age and with biological age, a measure of how old the body appears. Those with more hasslers showed biological ages above their actual years. Each additional hassler was associated with about 1.5% faster biological aging, or roughly nine months more biological age at the same chronological age.
The team accounted for other possible explanations, including occupation, adverse childhood experiences and smoking, and the association held. Family and friends who created difficulties mattered most, while spouses did not show the same pattern, a difference the source does not explain. Hasslers were also linked to depression, anxiety and higher body mass index.
The authors frame negative social ties as possible chronic stressors and an overlooked biological risk factor, and they call for interventions that reduce harmful social exposures. They are equally clear about the limits: this is correlation, not proof that hasslers cause faster aging. Studies designed to test cause and effect are the necessary next step.
A study published last month in the Proceedings of the National Academy of Sciences puts a number on something many people have long suspected: the people who make your life harder may also be making your body older.
The researchers looked at what they call hasslers, defined as people in a person's social environment who create problems or make life more difficult. They compared the number of hasslers in each person's life against two measures of age: the one on the birth certificate, and biological age, which reflects how old the body appears to be. People with more hasslers had a biological age higher than their chronological age.
The size of the effect is specific. According to the authors, each additional hassler is associated with about 1.5% faster biological aging. That works out to roughly nine months of added biological age among people of the same chronological age.
The researchers also tried to rule out the obvious alternative explanations. The analysis accounted for several other factors, including occupation, adverse childhood experiences and smoking. Even so, the authors report, the impact of negative social ties remained significant.
Not every hassler counted equally. Hasslers who were family members or friends showed what the study calls detrimental associations. Spouse hasslers did not show the same pattern. The source does not say why the results differ by relationship.
Biological aging was not the only association. Hasslers were also linked to a range of adverse mental and physical health outcomes, including depression, anxiety and higher body mass index.
The authors write that the findings suggest hasslers in one's social environment may be an overlooked but consequential biological risk factor. Taken together, they say, the results point to negative social ties acting as chronic stressors in biological aging. They also point to a need for interventions that reduce harmful social exposures in order to promote healthier aging.
The authors are careful about what the study cannot show. The findings are associations, and they do not prove a causal effect of negative social ties on aging processes. In other words, the study shows that more hasslers and older biological age go together. It does not establish that the hasslers are the cause. Studies designed to test cause and effect would be the next step.
