The Positive Impact of Social Connections on Cognitive Health

How to become more socially engaging and reap the benefits

The emotional brain craves meaningful connections requiring a socially integrated lifestyle for health and happiness.

Maintaining cognitive health has become important as the aging population grows and mental health issues soar. Cognitive decline and impairment can adversely impact the quality of life and daily activities.

Many factors can contribute to cognitive decline and impairment. Decades of research in cognitive science, neuroscience, psychology, psychiatry, and longevity studies have revealed surprising links between social connections and cognitive health.

In every mental health story, I intentionally touch on the importance of meaningful social connections, which are critical for our cognitive health, overall well-being, and living a fulfilling life.

Over the last three decades, I studied the significance of social connections for our cognitive system and mental health. I also observed the phenomenon of centenarians and reviewed the papers from longevity and ethnographic studies.

Some readers privately approached me and asked what if they don’t enjoy social settings and stay away from gatherings purposefully. This is a valid concern. I answer this question briefly in the following sections.

Social intelligence is coded in our DNA. We evolved as social beings throughout history. The brain is hardwired in a way, craving for tribal connections. The limbic system (the emotional part of the brain) is designed to cater to social needs.

Social intelligence is complex but manageable. By understanding the fundamentals, we can improve our social skills. Further, by emulating the behaviors of socially savvy people, we can improve our social competence.

I focus on using accumulated knowledge to keep our cognitive function. I highlight the correlation between social connections and cognitive health by explaining the importance of a socially integrated lifestyle, emphasizing our limbic system and associated biochemicals.

I constructed this piece under six sections to make it easy to digest. It reflects the critical points of my decades of research in the field without going into scientific or technical details.

What is the limbic system, and why does it matter?

I previously documented my perspectives and experiences on the limbic system in a story titled Here’s How I Tame the Limbic System to Regulate My Emotions in 10 Steps.

I want to introduce its importance briefly, as the limbic system is critical to our ability to form and maintain meaningful social connections.

The limbic system is a convoluted part of the brain with several parts and many neural connections. According to theories, it can trigger and process emotions and emotional memories.

The significant components of the limbic system are the amygdala, the hypothalamus, the hippocampus, and the cingulate gyrus.

The system is connected to other brain regions (the pituitary gland) and various organs. Damages to the limbic system and its connections are linked to emotional disorders.

The amygdala is the alert system of the body. The hypothalamus controls the endocrine system’s physiological responses to stress. The hippocampus forms memories. The cingulate gyrus regulates emotional responses.

When the amygdala and cingulate gyrus are activated, we feel anxiety and fear recorded and stored by the hippocampus as memories. Excessive electrical activities in the limbic system can manifest as seizures.

The most significant risk factor for the limbic system is oxidative and emotional stress. Excessive stress can over-activate the nervous system and cause the generation of unpleasant emotions like anxiety, fear, anger, guilt, grief, or shame, which later might turn into depressive feelings.

The activities of the limbic system can impact cells, tissues, organs, and other systems in the body. Its components and connections work together to ensure that the body can respond appropriately to different emotional states for survival.

The Meaning of a Socially Integrated Lifestyle

A socially integrated lifestyle is a way of life in which we actively engage with the community and develops social connections and relationships with others from different backgrounds.

A socially integrated lifestyle can lead to increased happiness, better mental and physical health, and a sense of belonging within the community.

Several mechanisms facilitate a socially integrated lifestyle, like community involvement, cultural exchange, shared interests, and social media.

Volunteering provides opportunities to develop new skills and gain valuable experience. Attending community events like festivals or concerts can help us meet new people and build relationships with others with similar interests.

Joining a sports team is a great way to meet new people and build relationships through a shared interest in sports.

Traveling is an excellent way to experience different cultures and meet new people. By engaging with locals and learning about their culture, travelers can build lasting relationships and gain new perspectives on life.

Theories and Mechanisms Behind the Link Between Social Connections and Cognitive Function

Several theories explain why social connections are essential for cognitive health. They inform that engaging in social activities can provide mental stimulation to help maintain cognitive function.

One of these theories is the social support theory which informs that social connections can improve cognitive function by providing emotional support and a sense of belonging.

Another theory is the social engagement theory which suggests that social engagement can help maintain cognitive function by providing mental stimulation and opportunities for learning.

I want to touch briefly on the mechanisms. One of the key mechanisms behind the link between social connections and cognitive health is the concept of cognitive reserves.

Cognitive reserve refers to the brain’s ability to compensate for damage or changes that can lead to cognitive decline. Social connections can build cognitive reserves by providing mental stimulation, reducing stress, and increasing feelings of belonging and purpose.

Social connections can provide mental stimulation by providing opportunities for learning and problem-solving. Engaging in stimulating conversations, playing games with others, and attending cultural events can help provide mental stimulation and build cognitive reserve.

Oxidative and emotional stress can harm cognitive function. Social connections can reduce stress by providing emotional support and a sense of belonging. Feeling connected to others can reduce feelings of loneliness and anxiety, which can improve cognitive health.

Social connections provide a sense of belonging, which helps promote feelings of purpose and overall well-being. A sense of belonging and purpose can improve cognitive health by reducing depressive thoughts.

From my years of research into neurotransmitters, I learned that when we engage in social bonding activities, the brain releases oxytocin, enabling love, intimacy, admiration, connection, and trust.

Similarly, when we engage in social activities such as group laughter and dancing, the brain releases dopamine and serotonin, reinforcing our social behavior and motivating us to continue seeking social connections.

Examples of Meaningful Social Connections

Social connections have long been recognized as integral and essential to overall health and well-being. Recent studies have shed light on the specific ways in which social activities can help improve cognitive health.

I want to touch on helpful social connections and give a few examples that can positively impact cognitive health.

Volunteering

Volunteering not only benefits the community but can also benefit us by building social connections and providing a sense of purpose and belonging. The social engagement provided by volunteering can help improve cognitive function, including memory and attention.

Group Exercises

Group exercise classes allow us to exercise and work towards fitness goals collaboratively. The social connections formed in these classes provide a sense of accountability and motivation, which can increase adherence to exercise regimens, provide neurostimulation to build cognitive reserves, and improve cognitive function.

Cultural Events

Attending cultural events, such as plays, concerts, and museum exhibits, can provide mental stimulation and build cognitive reserves. These events offer opportunities for us to learn and engage with new ideas and perspectives. They can provide a sense of belonging and community spirit.

Other Social Connections

Besides the examples above, other ways to build and maintain social connections can positively impact cognitive health. For instance, joining social clubs, a book club, or attending religious services can provide opportunities to meet new people and build social connections.

What if you don’t enjoy social connections for some reason?

Social connections are essential for well-being. However, not everyone enjoys social settings or feels comfortable in group gatherings for various reasons, such as social anxiety, introversion, or past negative experiences.

Social anxiety is a psychological condition characterized by an intense fear of social situations and excessive self-scrutiny. Excessive self-examination can lead to avoidance of social settings.

Studies indicate that people with social anxiety have increased activity in the amygdala when faced with social situations. This biochemical imbalance in the brain can lead to feelings of fear, anxiety, and discomfort.

In addition, some people might not find social interactions as rewarding as others due to differences in their brain chemistry, like low dopamine or serotonin levels, making social situations less enjoyable.

Furthermore, introversion is a personality trait that refers to a preference for quiet and solitude over social interactions.

Some people may also have past negative experiences in social settings, such as bullying or rejection, which can lead to a fear of social situations.

Not enjoying social settings does not necessarily mean a person is unhappy or isolated. Introverts, for example, may prefer smaller, more intimate gatherings and feel energized by alone time.

Additionally, some people who do not enjoy social settings can still form and maintain meaningful social connections through alternative means, such as one-on-one interactions, online communities, or shared interests.

Everyone’s preferences and comfort levels are different. It is okay to prioritize self-care and social situations that feel comfortable and enjoyable.

Some people may work on overcoming their discomfort in social situations through therapy or gradual exposure. Others may focus on building relationships in alternative ways.

In general, starting small is a viable approach. If social gatherings make you uncomfortable, you may attend smaller events with people you know well. You could also meet with one or two friends for a drink or a meal.

Finding common interests can be helpful. Joining a club or group that focuses on something you enjoy, such as a book club or a hiking group, can be a great way to meet new people and build relationships through shared interests.

Technology also can help. Social media and messaging apps can be useful tools for staying connected with others, even if you don’t enjoy face-to-face interactions as much. You may try joining online communities covering your interests.

However, if you notice your discomfort in social settings is causing significant distress or impacting your daily life, it will be valuable to seek professional help from a therapist or counselor.

There might be underlying psychological and emotional issues that professionals might diagnose, unfold, and treat.

There is no single or right way to build social connections. There are many ways and options suiting our goals and personality. It is essential to find what works best for you.

Building meaningful relationships takes time and requires effort. However, it’s worth the effort and time for the benefits it can bring to your overall well-being.

Insights from Growing Literature

A growing literature indicates that more socially active people are less likely to suffer from cognitive impairment in the long run.

Since there are hundreds of papers, I’d like to provide perspectives from two review stories, one in 2004 and another in 2018. They cover the findings and perspectives of many studies in the last two decades.

An active and socially integrated lifestyle in late life might protect against dementia.

A 2024 review in Lancet’s Neurology mentioned that an active and socially integrated lifestyle in late life might protect against dementia.

This review systematically analyzed the published longitudinal studies exploring the effect of social networks, physical leisure, and non-physical activity on cognition and dementia.

Then it summarised the current evidence with the limitations of the studies and the biological plausibility.

Considering the accumulated evidence and the biological plausibility of the hypotheses, researchers concluded that an active and socially integrated lifestyle in late life protected against dementia and Alzheimer’s disease.

The Association between Social Engagement, Loneliness, and Risk of Dementia: A Systematic Review and Meta-Analysis.

This 2018 meta-analysis pointed out poor social engagement indices were associated with increased dementia risk, including poor social networks and social support.

In long-term studies of more than ten years, good social engagement was modestly protective. Loneliness was non-significantly associated with increased risk.

Their findings encourage interventions targeting social isolation and disengagement for dementia prevention. The positive impact of social connections on cognitive health is not limited to the elderly or older adults.

Social engagement and connectedness are essential for people of all ages, including children, as they can build resilience, create cognitive reserves, lower stress, and reduce the risk of cognitive decline and impairment.

Six Tips for Maintaining Social Connections

Building and maintaining social connections can be challenging for people who have introverted tendencies and experiencing cognitive decline.

1 — Stay in touch with family and friends.

Consider contacting family members, relatives, and friends to form social connections. If you cannot meet face to face, try to call, text, or video chat with loved ones regularly.

2 — Serve as a volunteer.

Volunteering is great for meeting new people and working together towards a common goal. You may check volunteer opportunities in your community that align with your interests or skills.

3 — Join a club or group activities.

Joining a club or group based on a common interest can be a great way to build social connections. You may join groups in your community that focus on hobbies or interests you enjoy, such as gardening, book clubs, hiking groups, or exercise groups like yoga, Pilates, or water aerobics.

4 — Attend conferences, seminars, or community events.

Besides professional conferences and seminars, you may join community events and activities open to the public, such as concerts, festivals, and farmers' markets. Attending these events can be a great way to meet new people and build social connections.

5 — Enhance your knowledge and gain new skills.

Improving your knowledge and acquiring new skills can help you meet new people and provide mental stimulation. Look for classes or workshops in your community that teach skills like cooking, painting, writing, public speaking, language learning, fitness, and stress management.

6 — Join online groups and forums.

If leaving the house is difficult, you may join online groups or attend virtual events. Many organizations offer online classes or virtual social events to help you build social connections from the comfort of your home.
