Anxious Worriers With This Personality Profile Had 35% Lower Mortality Risk

Not All Anxiety Is Bad? Scientists Found One Type That May Actually Help You Live Longer

Being a worrier is usually seen as a health liability. Stress, anxiety, sleepless nights: conventional wisdom has long treated high neuroticism as bad news for longevity. A large new study throws a wrench into that assumption, finding that one particular flavor of anxious personality is linked to a 35% lower risk of death over 15 years, lower rates of several lifestyle-linked conditions, and healthier day-to-day choices. As a group, people with this profile also had better 15-year survival than those with zero neuroticism scores.

Neuroticism is one of the “Big Five” personality traits, a spectrum capturing how prone someone is to negative emotions like worry, irritability, and mood swings. For decades, scoring high on neuroticism has been tied to poor health outcomes, mental illness, and even early death. But researchers at institutions including the Chinese Academy of Sciences and Beijing Normal University noticed something hidden in the data. Not all neuroticism looks the same, and the differences matter enormously for health.

Drawing on personality data from more than 400,000 people, plus UK Biobank medical records, brain scans from more than 30,000 participants, and genetic data from more than 267,000, the team published their findings in the journal Science Bulletin.

Two distinct dimensions of neuroticism emerged, and they work in opposite directions. One tracks the overall intensity of negative emotions, the classic, harmful kind of neuroticism. But the other, which the researchers named ERIS (Emotional Reactivity and Internal Stability), appears to be quietly protective. High scorers on ERIS tend to worry and feel anxious, but they don’t experience the wild mood swings or emotional meltdowns tied to the more damaging dimension.

Worriers Who Live Longer: What the ERIS Personality Dimension Reveals

To find these dimensions, the team analyzed neuroticism questionnaire responses from five independent study groups spanning different ages, cultures, and measurement tools, totaling 403,743 participants. Rather than treating neuroticism as a single score, they mapped how people’s emotional response patterns cluster together across a population. A consistent, two-part structure emerged across every dataset.

High-ERIS individuals score higher on worry-related responses (feeling anxious, nervous, tense) while scoring lower on items tied to mood instability, like frequent mood swings or feeling perpetually fed up. Low-ERIS individuals show the reverse: less anxiety but more emotional volatility. This dimension turned out to be statistically independent from overall neuroticism, meaning it captures something genuinely different.

Across more than 15 years of follow-up data from the UK Biobank, a long-running British health study, the numbers were hard to ignore. High-ERIS individuals had a 35% lower mortality risk compared to low-ERIS individuals with the same overall neuroticism scores. Even more unexpectedly, as a group they also outlasted those with the lowest neuroticism scores, the people previously assumed to be the healthiest. Protective associations extended to specific causes of death, including ischemic heart disease, lung cancer, and COVID-19.

A 35% Survival Edge Tied to Risk-Averse Neuroticism Behaviors

ERIS was also strongly tied to healthier behaviors. High-ERIS individuals were far less likely to smoke or take risks, more likely to quit smoking successfully, more inclined toward moderate exercise and Mediterranean-style eating, and more likely to seek out preventive medical care. Worth noting: these individuals actually reported worse general health and more long-standing illnesses than their low-neuroticism counterparts, yet they still lived longer. Researchers suggest the advantage may partly stem from vigilance-driven, proactive healthcare behavior rather than better baseline health alone.

General neuroticism told a darker story. High scorers were more likely to suffer from mental and physical conditions, sleep poorly, attempt suicide, and report lower life satisfaction across nearly every domain.

Neuroticism and Longevity: Ancient Brain Circuits, Separate Genes

Brain scans from more than 30,000 participants offered one possible clue. General neuroticism was associated with structural differences in cortical regions, the “thinking” parts of the brain tied to emotion regulation and self-monitoring, suggesting those areas may be less effective at keeping negative emotions in check. ERIS, by contrast, was linked to older subcortical structures: the amygdala, hippocampus, thalamus, and cerebellum, regions involved in basic fear and threat responses, the kind of system animals rely on when they sense danger.

Genetic data backed this up. A genome-wide study of 267,262 participants found the two dimensions have largely separate genetic underpinnings. Traditional neuroticism genes showed substantial overlap with parts of the human genome that evolved rapidly and recently, changes specific to humans. ERIS genes did not show a statistically significant enrichment in those regions, suggesting ERIS taps into a far older emotional system shared across species.

Across the animal kingdom, researchers have observed what they call a “shy-bold continuum”: some animals are naturally bolder and more risk-tolerant, others more cautious and threat-aware. One interpretation is that high-ERIS individuals may resemble the cautious end of that spectrum, people whose threat radar pushes them away from avoidable risks. General neuroticism, by contrast, may be a more recent human development tied to the brain’s ability to ruminate and generate stress about abstract problems. That kind of worry, untethered from real-world danger, appears to wear the body down over time.

A 35% gap in mortality risk between personality subtypes is not a small signal. Whether anxiety is the ancient, threat-sensing kind or the modern, rumination-driven kind may turn out to matter more than how much of it a person carries.
