Difficult Friends Age You Faster? Study Links 'Hasslers' to Accelerated Biological Aging

• A new study in PNAS explores how 'hasslers' – individuals causing persistent stress in social networks – impact biological aging.
• Researchers found that each additional 'hassler' was associated with roughly nine months higher biological age and a 1.5% faster pace of biological aging.
• The effect was strongest for difficult family relationships, with 10% of parents and children classified as 'hasslers' compared to 3.5% of friendships.
• Negative relationships with spouses/partners did not show the same accelerated aging link, possibly due to mitigating support.
• The study suggests that negative social ties act like other chronic stressors, influencing health and well-being, with accelerated aging as a potential outcome.
