A study, based on data from over 2,300 respondents across different age groups, analyzed how relationships with people who frequently cause problems affect the body. Researchers labeled such individuals as "stressors"—people who often provoke conflicts, make daily life difficult, or emotionally drain others.
The results show that nearly one-third of respondents have at least one such person in their social circle, while about 10 percent have two or more.
The most important finding of the study is that each additional stressful person in one's close environment can accelerate the pace of biological aging by approximately 1.5 percent. This means the body ages faster than its actual chronological age.
Experts explain that such relationships are a source of chronic stress, which triggers a series of biological reactions in the body. Levels of stress hormones like cortisol increase, inflammatory processes occur, and cell damage takes place, which in the long term can lead to faster aging and a higher risk of diseases.
Although the research does not prove a direct cause-and-effect relationship, scientists emphasize a strong link between negative social relationships and impaired health.
Individuals who already have health problems or are exposed to other forms of stress are particularly affected, and women more frequently report such negative interactions.
Researchers stress that not all social relationships are harmful—on the contrary, quality and supportive connections can have the opposite effect and contribute to a longer and healthier life.
As possible solutions, experts recommend setting clear boundaries in relationships, reducing contact with stressful individuals, and nurturing positive social connections that contribute to mental and physical well-being.
