Relationship x Aging

 That headline is based on a new 2026 study suggesting that certain stressful people in your life — sometimes called “hasslers” — may actually speed up biological aging and potentially shorten lifespan.

Here’s what the research found:

What the study actually showed

• Researchers surveyed ~2,000+ people and analyzed epigenetic (DNA-based) markers of aging from saliva samples.  
• Each additional stress-causing relationship was linked to about a 1.5% faster aging pace.  
• On average, one “hassler” corresponded to ~9 months of extra biological age.  
• Family members, coworkers, roommates, and friends were common sources — not just romantic partners.  
• The effect appeared stronger when people had two or more draining relationships.  

Why draining people affect your health

Scientists think it’s due to chronic stress, which can:

• Raise cortisol
• Increase inflammation
• Disrupt sleep
• Weaken immunity
• Affect heart and metabolic health

Over time, those changes show up as accelerated biological aging, which is linked to earlier disease and mortality risk.  

Interesting twist

One surprising finding:

• Spouses who “hassle” didn’t show the same negative effect, possibly because close relationships also provide emotional support.  

What counts as a “draining” relationship

The study describes people who:

• Constantly criticize
• Create conflict
• Demand emotional energy
• Cause anxiety before/after interactions
• Add problems instead of support

Important caveat

This doesn’t prove causation — it’s an association. But the biological markers make the link stronger than earlier psychology-only studies.  

Practical takeaway

Researchers suggested:

• Set boundaries
• Reduce exposure where possible
• Balance with supportive relationships
• Build broader social networks

Positive relationships actually protect longevity, so it’s not “people are bad” — it’s chronic stressful ones that matter.
