Discover the transformative power of social connections and how nurturing stronger bonds can lead to a longer, healthier, and happier life.
Chronic loneliness can have devastating effects on our physical and mental well-being. According to social scientist Kasley Killam, good quality social connections are a fundamental human need that has been overlooked for too long.
Loneliness affects approximately 43% of adults in the United States, with older adults being more susceptible.
It is often linked to social isolation, lack of meaningful relationships, and feelings of disconnection.
Research suggests that loneliness can have severe physical and mental health consequences, including increased blood pressure, anxiety, and depression.
Addressing loneliness requires a multifaceted approach, incorporating social support networks, community engagement, and accessible healthcare services.
Why Social Health Matters
Traditionally, human health has been divided into two components: physical and mental. However, Kasley Killam argues that a third pillar – social health – is essential in determining our overall well-being. Connection has a profound impact on our health, happiness, and longevity, yet it’s often neglected.
Social health refers to an individual's ability to interact and connect with others in their community.
It encompasses emotional, social, and psychological well-being.
Factors that contribute to good social health include strong relationships, a sense of belonging, and effective communication skills.
Statistics show that people with strong social connections tend to have better mental and physical health outcomes.
In contrast, social isolation can lead to increased stress levels, anxiety, and depression.
The Consequences of Social Isolation
Research has shown that the lack of social connections increases the risk of various diseases, including stroke and dementia. In fact, studies have found that we’re two to three times more likely to die in the next decade if our relationships are lacking, regardless of our mental and physical health. This is comparable to regularly smoking and excessive drinking, being obese and physically inactive.
Social isolation is a state of disconnection from others, which can have severe consequences on physical and mental health.
According to the American Psychological Association, adults who experience social isolation are more likely to develop depression, anxiety disorders, and even cardiovascular disease.
Statistics show that over 40% of adults in the United States report sometimes or always feeling alone.
Chronic loneliness can also impair cognitive function, leading to a decline in memory and problem-solving skills.
How Chronic Loneliness Affects Our Bodies
One leading theory is that chronic loneliness increases cortisol, inflammation, and weakens our immune systems. Our bodies register chronic loneliness as a threat, which can lead to serious health consequences. However, when we have supportive relationships, it calms down our body and allows us to manage stress more easily.

The Root Causes of the Social Health Crisis
Kasley Killam identifies several factors contributing to the current state of social health, including technology and social media. While these tools can be beneficial, they often serve as substitutes or crutches for meaningful human connection. Additionally, trends in our work culture, such as prioritizing careers over relationships, and living alone, also play a significant role.
The Impact of COVID-19 on Social Health
Interestingly, studies have shown that while the pandemic initially led to increased isolation and loneliness, people adapted and became resilient. In fact, community resilience was found to be a key factor in reducing cases and deaths from COVID-19.
Building Stronger Social Connections
Kasley Killam advocates for proactive measures to build up social health, such as community initiatives like Super Neighbors and social prescribing. These programs link patients to community groups and services, promoting personalized care and stronger social connections.
The Rise of the Social Health Movement
With the establishment of the WHO’s commission on social connection and the US surgeon general’s advisory on loneliness and isolation, it’s clear that social health is becoming a growing concern. Kasley Killam believes that we’re seeing the start of a social health movement, with innovation and industry growth accelerating in the years ahead.
Conclusion
As Kasley Killam puts it, ‘Connection is a fundamental need that our bodies understand.’ By prioritizing social connections and building stronger relationships, we can unlock a longer, healthier, and happier life. It’s time to recognize the importance of social health and work towards creating a more connected world.
