Difficult People May Age You Faster, Study Suggests
Each additional hassler: about nine months of added biological age
Mark
What is a "hassler," exactly? It sounds casual for a scientific paper.
Mimi
The authors define it as someone who creates problems or makes life more difficult. It's about the effect on your life, not a diagnosis of the other person.
Mark
And the headline number?
Mimi
Each additional hassler is associated with about 1.5% faster biological aging, roughly nine months of added biological age compared with someone of the same chronological age.
Luke
Worth stressing the word "associated." The authors say the findings don't prove negative social ties cause aging.
Mark
Did they check for obvious alternative explanations?
Mimi
They accounted for occupation, adverse childhood experiences and smoking, among others. The link stayed significant.
Luke
Accounting for those factors still leaves room for things they didn't measure. The source doesn't say how hasslers were identified beyond the definition, so I'd hold the precision loosely.
Mark
Why would spouses differ from family and friends?
Mimi
The reporting doesn't say. Family and friend hasslers showed detrimental associations; spouse hasslers did not.
Luke
Right, and that's an open question, not an explanation. Also, biological age has no single definition, and there's no definitive proof that aging faster this way means dying sooner.
Mark
So what's solid?
Mimi
The pattern, including links to depression, anxiety and higher body mass index. What it means for any one person is still unsettled.
Der Puls
- A study of 'hasslers' in people's social circles has linked each additional difficult contact to roughly 1.5% faster biological aging.
- The disruption lands closest to home, as family and friends carry harmful associations while spouses do not.
- Researchers are reaching for interventions that reduce harmful social exposures, though no trial has yet tested them.
- The signal remains an association, and the field still lacks a single agreed definition of biological age.
A recent study in the Proceedings of the National Academy of Sciences gives numerical shape to an old intuition: that the difficult people in our lives may weigh on the body as well as the mind. Researchers found that each additional person who creates problems in someone's circle of family and friends tracked with biological aging roughly nine months ahead of the calendar, even after accounting for occupation, childhood hardship and smoking. The finding is a signal of association rather than proof of cause, and it invites a longer human question about how closely we are bound to those we cannot easily leave.
A study published last month in the Proceedings of the National Academy of Sciences offers a number for a feeling many people already carry: that the people who make life harder may be aging us faster. The researchers focused on 'hasslers,' people in one's social circle who create problems or make life more difficult. Those with more hasslers showed a biological age higher than their calendar age would predict, with each additional hassler associated with about 1.5% faster aging, or roughly nine months.
Not all hasslers weighed the same. Family members and friends showed harmful associations with biological aging, while spouses did not. The link held after the researchers accounted for occupation, childhood adversity and smoking. Depression, anxiety and higher body mass index were also associated with the presence of hasslers.
The authors describe negative social ties as chronic stressors and call for interventions that reduce harmful social exposures. They are equally clear about the limits: these are associations, not proof of cause, and biological age has no single definition. What comes next is whether follow-up work can establish cause and effect, and whether the proposed interventions prove effective.
A study published last month in the Proceedings of the National Academy of Sciences puts a number on something many people suspect: the people who make life harder may be making you older, at least biologically.
The researchers focused on what they call "hasslers," meaning people in one's social circle who create problems or make life more difficult. They found that people with more hasslers in their lives had a higher biological age than their chronological age would predict.
The size of the effect is specific. According to the authors, each additional hassler is associated with roughly 1.5% faster biological aging. That works out to about nine months of additional biological age among people who are the same age on the calendar.
The researchers tried to rule out other explanations. The analysis accounted for occupation, adverse childhood experiences and smoking, among other factors. Even so, the link between negative social ties and faster aging remained significant, the study notes.
Not every hassler counted the same. Hasslers who were family members or friends showed what the authors call "detrimental associations" with biological aging. Hasslers who were spouses did not.
Aging was not the only measure affected. The presence of hasslers was also associated with several adverse mental and physical health outcomes, including depression, anxiety and a higher body mass index.
The authors wrote that the results suggest hasslers in one's social environment may be "an overlooked but consequential biological risk factor." They described negative social ties as chronic stressors and called for interventions that reduce harmful social exposures in order to promote healthier aging.
The authors are also 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. Beyond that, there is no single definition of biological age, and no definitive research establishes that faster biological aging leads to earlier death.
So the study offers a measured signal rather than a verdict. What to watch for is whether follow-up work can test cause and effect, and whether the interventions the authors call for are tried and shown to make a difference.
