Key Takeaways
  • It can be hard to make and maintain friendships as an adult, but research shows that the benefits are worth it.

  • Friendships can lower stress and help regulate your body’s response to it, which may protect both your mental and physical health.

  • Feeling satisfied with your friendships — even if you don’t have many — can reduce loneliness, depression, and suicide risk.

It’s well-documented that having a strong support network, including friendships, is key to mental health. But some reports show that we’re in a “friendship recession,” with American adults — especially men — having fewer friends than ever. At the same time, people are experiencing higher rates of loneliness and isolation

Even if it’s hard to make friends as an adult, the benefits are worth it. Here are several reasons why you should invest in platonic relationships. 

Friendships reduce stress 

Research shows that having strong and positive friendships can significantly reduce stress in the workplace, in life, and when overcoming adversity. One study found that having friends at work helped medical professionals manage their job-related stress. Another review found that good friendships could buffer the neurobiological effects that childhood adversity can have on adolescent brains. 

In some cases, friendships can become a significant source of stress as well. This is especially true in toxic or abusive friendships. The key is to build healthy, long-lasting friendships. It can help to learn how to manage conflict, set boundaries, increase self-esteem, and practice self-compassion. These can all be buffers to making unhealthy friendships and maintaining healthy ones.

Friends can boost your resiliency 

Resilience is your ability to withstand and bounce back from life’s challenges, including traumatic events. We can’t prevent bad things from happening, but research shows that having good friends can make you significantly more resilient in the face of adversity. Your friends can offer support, encourage you to keep going, and help you find meaning when life feels overwhelming.

One study found that 14-year-olds who experienced trauma were more resilient with high-quality friendships. Another study indicated that teenagers who felt they had strong friendships were found to be more resilient.

A strong social network protects you from loneliness 

Having close friends helps you feel like you matter and boosts a sense of belonging. Loneliness increases your risk for many physical and mental health problems. For example, lonely older adults have a higher mortality risk. Loneliness also increases your risk for mental health conditions like depression.

When you have good relationships with your friends, you’re more likely to feel seen, valued, and understood. Just having someone to call or spend time with can help loneliness go away.

Research shows that it isn’t necessarily about the number of friends you have. It’s more about how satisfied you are with the relationships. So, it might be beneficial to set realistic expectations for your friendships. 

Friendships can help you learn and strengthen empathy 

Empathy is a socioemotional skill that’s linked with stronger relationships, healthier conflict resolution, and better communication. People who are more empathetic are more likely to have higher life satisfaction and self-esteem.

Friendships give you a chance to practice empathy. You listen, notice how your friend feels, and imagine what it’s like to be in their place. Over time, this makes it easier to connect with friends, family, and other people in your life.

Having friends lowers your depression and suicide risk

Research shows that strong friendships can lessen depression risk and severity for both teens and adults.

But when you live with depression, you may be more likely to withdraw socially. You may not have the energy to meet with your friends. You might believe that you’re a “burden” or not worthy of friendship. Know that this isn’t true, and everyone deserves fulfilling relationships in their lives.

For some people with depression, having good friends can literally be a matter of life or death. Research has found that friendship quality can significantly lower suicide risk.*

If negative thoughts or depression are getting in the way of building lasting friendships, talking with a therapist could help.

Social support matters

Lastly, having friends provides you with someone to talk to and count on — both in times of joy and of need. Being able to share good news can make it feel more meaningful. And when life feels difficult, friends can listen, validate your feelings, and remind you that you matter.

Social support can be especially important when you live with a mental health condition. Having friends who understand your symptoms can make it easier to ask for help. Your friends can encourage you to keep up with treatment and help you feel less shame around your condition.

Tips to build and maintain healthy friendships

If you’re having a hard time making and keeping friends, you’re not alone. Friendships require time, effort, and patience. But it’s never too late to start. 

Explore these tips: 

  • Reframe negative thoughts. You may find yourself thinking, “Who’d want to be friends with me?” or, “Making friends is impossible at my age.” It may be helpful to push back against these thoughts and focus on your strengths, like your sense of humor or compassion, for example. A reframe might sound like, “I have a lot to offer a friendship. It’s just about finding the right people.”

  • Consider the places you frequent. You don’t have to completely change your schedule to meet new people. Think about the places you already go, like church or a local cafe, and consider interacting with other people there. A friendship can emerge from a simple conversation or a shared interest. 

  • Reach out to people you already know. Are there people in your current social circle who you’d be interested in getting to know better? This can also be a good place to start. Take an inventory of acquaintances, and consider reaching out to those who you believe could become friends. Deepening the relationships you already have can be a more manageable start to building and strengthening friendships. 

Clinician's take
Time constraints, competing responsibilities, and geographic mobility can make maintaining a friendship difficult. Rebuilding and nurturing friendships in adulthood can be deeply protective for mental health. Start small, such as weekly text check in. Over time, you can feel more comfortable calling and sharing deeper things going on.
