I'm a Therapist—Why Adults Should Never Stop Making New Friends

Therapists emphasize that adults should continue making new friends throughout their lives, highlighting the critical role such relationships play in mental and physical health. Rebecca Boone, a licensed mental health counselor and clinical director at Woodlands Grove Recovery Campus in Ohio, argues that forming new connections offers unique benefits for emotional regulation, resilience, and cognitive growth. Her insights come amid growing concerns over loneliness, which affects millions of Americans and has been linked to serious health risks including heart disease, stroke, and dementia. Recent data underscores the prevalence of loneliness among adults. A 2023 Pew Research Center survey found that 53 percent of adults have between one and four close friends, while 38 percent have five or more. However, 8 percent report having no close friends at all. Meanwhile, Forbes reported that 58 percent of Americans feel lonely regularly. The health consequences of prolonged isolation are severe. According to Harvard Magazine, the mortality risk associated with loneliness is comparable to smoking 15 cigarettes daily. The U.S. Department of Health notes that loneliness increases the risk of heart disease by 29 percent, stroke by 32 percent, and dementia by 50 percent in older adults. Additionally, a lack of social connection is associated with a more than 60 percent higher risk of premature death. Boone explains that new friendships challenge the brain’s preference for routine by exposing individuals to novel perspectives, lifestyles, and cultural experiences. This cognitive “friction” promotes learning, self-development, and new ways of understanding the world. She describes how these interactions can be energizing, as they encourage the brain to form new neural connections rather than relying on established patterns. Expanding one’s social circle can also prevent stagnation, according to Boone. Feeling stuck is not always due to a lack of motivation but can result from a dearth of new experiences. Relationships introduce fresh conversations, activities, and ways of thinking, helping individuals break free from repetitive routines. By widening their social networks, people gain access to new opportunities and possibilities they might not have otherwise considered. This expansion can also influence how the brain envisions future scenarios, opening up a broader range of potential outcomes. Diverse friendships, Boone adds, enhance psychological flexibility, the capacity to adjust beliefs and perspectives in response to new information. Engaging with people from varied backgrounds fosters curiosity, empathy, and resilience in unfamiliar situations. Such relationships serve as practical training grounds for navigating discomfort, teaching individuals that both safety and growth can coexist. Personal development often arises from recognizing that discomfort and security are not mutually exclusive. Boone warns that the signs of loneliness are not always clear-cut. People may not simply spend time alone but could start defining themselves through isolation. This subtle shift can lead to a diminished sense of belonging and purpose. Recognizing these signals early is crucial for seeking support and building new connections. Experts suggest that actively pursuing new friendships can counteract the negative impacts of loneliness and contribute to overall well-being. Whether through community groups, hobbies, or professional settings, creating opportunities for interaction helps maintain a dynamic and supportive social environment. As Boone emphasizes, fostering new relationships is not merely a social choice but a vital component of mental and physical health.
