Have you ever noticed that spending time with certain people leaves you feeling drained or anxious? It turns out that these stressful relationships may do more than affect your mood. A recent study suggests that constant interaction with difficult people may actually influence your health and even accelerate the natural aging process.
Researchers have identified a category of individuals they call "hasslers." These are people who create problems or make life more complicated for those around them. According to a study funded by the National Institute on Aging and published in the journal Proceedings of the National Academy of Sciences, interacting frequently with hasslers may increase stress levels and influence biological aging.
Biological aging refers to how quickly your body’s cells age. This can differ significantly from chronological age, which is based on the number of years since birth. In other words, your body can age faster or slower than your calendar years, depending on various factors including lifestyle, genetics, and social environment.
The research team analyzed survey data from over 2,000 participants in Indiana. People were asked to reflect on their relationships over the past six months and identify how often someone in their life hassled them, caused problems, or made their life more difficult. Participants also reported their overall health, and saliva samples were collected to measure epigenetic markers, which are indicators of biological aging.
The results revealed a clear trend. For each additional hassler a person interacted with regularly, the pace of biological aging increased by approximately 1.5 percent. In practical terms, a person with one extra difficult person in their life might age about 1.015 biological years for every calendar year.
Study co-author Brea Perry, a sociology professor at Indiana University, explained that small increases in biological aging can accumulate over time, potentially having long-term health effects.
It is important to note that this study shows an association rather than a direct cause-and-effect relationship. Lead author Byungkyu Lee, a sociology professor at New York University, emphasized that while there is a link between hasslers and aging, the research does not confirm that difficult people directly cause faster aging.
The study found that certain groups were more likely to report stressful relationships. Women reported having more hasslers than men. Experts note that women often feel the effects of social interactions more intensely, both positive and negative. Perry explained that women are likely to perceive problems that others are experiencing, feel them deeply, and carry that stress.
People with poorer health or challenging childhood experiences were also more likely to encounter hasslers in their lives. Additionally, family members were commonly identified as sources of stress, including parents and children. These relationships are often difficult to limit due to their integral role in daily life. Outside the family, coworkers, roommates, and neighbors were more frequently listed as hasslers compared to friends.
Although reducing contact with challenging individuals can benefit health, it is not always feasible, especially when family or colleagues are involved. Experts suggest that setting clear boundaries is essential. Recognizing the negative effects of hasslers allows you to limit the energy invested in these relationships while maintaining necessary interactions.
Strengthening connections with supportive people is equally important. Positive social relationships have been linked to numerous health benefits, including lower risk of cognitive decline, improved mental health, and longer life expectancy. On the other hand, social isolation and loneliness can have severe consequences. The World Health Organization estimates that loneliness contributes to approximately 871,000 deaths each year globally.
Perry highlighted the importance of spending time with people who provide emotional support and companionship. Debra Umberson, a sociology professor at the University of Texas at Austin, noted that social connections are essential for overall well-being and should not be overlooked.
Here are some practical approaches to reduce the impact of hasslers in your life:
This study highlights the profound impact social relationships can have on health. Constant exposure to people who create stress may accelerate biological aging, while supportive relationships can offer protection against various health challenges. Women, individuals with past health issues, and those with difficult childhood experiences may be particularly vulnerable to stressful interactions.
By recognizing the effects of hasslers, setting boundaries, and cultivating positive social connections, it is possible to reduce stress and promote healthier aging.
