Love, connectedness, and a sense of community are fundamental to human well-being and something we tend to take for granted. In terms of health, I have often spoke about the deep influence that social connection can have on both mental and physical health. Studies consistently show that strong relationships not only reduce short term stress, but can even increase lifespan – one study showing an increase of 50% increased risk of premature death from all causes!

Look at the Blue Zones, those famous regions of the world where people are most likely to liver over 100 and there is less incidence of chronic disease. One of the main commonalities of these areas, was a sense of community and social connection. Whilst various elements including diet and physical activity obviously must contribute to longevity, it is thought that it is the social connection within these tight knit connections which may play the most significant role. But why as a species, do we need this interaction with other human beings so much?

Love—whether romantic, familial, or platonic—releases oxytocin, our ‘love’ hormone that gives us emotional security, regulates stress and reduces anxiety. Oxytocin is released during childbirth and breastfeeding, part of that connection to our newborns, but as adults we both need and appear to thrive from oxytocin and is key to maintaining social bonds. Love and social connection can take many forms and perhaps the most overlooked is our sense of tribe or community which can be enhanced through singing and dancing together. Being part of a community is crucial as it not only provides a sense of belonging and support, it can help us navigate life’s challenges. In times of crisis, a supportive network can provide both emotional and practical help, reinforcing our resilience. And those who do engage in social activities and maintain close relationships tend to have lower rates of depression and cognitive decline in later life.

Loneliness, on the other hand, has been linked to chronic inflammation, weakened immune function, and a higher risk of early mortality – it is thought to increase premature death by up to 26%!  For healthcare practitioners, loneliness is as much of a challenge as smoking and obesity. Loneliness, like our hunger or thirst signals, is a sign from our minds that we’re just not getting the social connection that we need to thrive. Whether through friendships, family, or participation in a local or spiritual community, it is apparent that these shared experiences, collective purposes and deep connections are essential for a longer, healthier more fulfilled life.

Ultimately, human beings are wired for connection. Prioritising love (of any kind) friendship and community is not just a scientifically proven way to enhance health and longevity, but for most of us the ultimate path to happiness.
