Social lives, genes, and our healthSocial lives, genes, and our health
All In The Mind
Having a sense of meaning in life can protect against chronic disease—but those who lack social connection are more prone to ill health. We talk with Steve Cole about social genomics.

How Loneliness, Purpose and Social Life Shape Our Genes
Episode Overview
- Long-term, severe loneliness is linked to increased inflammatory gene activity and reduced antiviral responses.
- Adverse social environments such as poverty show a common gene expression pattern known as the conserved transcriptional response to adversity.
- Subjective feelings of loneliness and threat relate more strongly to harmful gene changes than simple counts of social contacts.
- A strong sense of purpose or meaning in life is associated with healthier gene expression, even amid difficult circumstances.
- Contemplative and wellness practices like meditation, Tai Chi and yoga have small but consistent positive effects on gene activity.
“It’s almost as though there’s a kind of an operating system level neurobiological process going on that’s running our bodies… but it’s not terribly well synced up with our conscious mind.”
Curious about how others navigate their sobriety journey? This conversation from *All In The Mind* goes much wider, looking at how everyday social life shapes bodies at the most microscopic level. You’ll hear Professor Steve Cole from UCLA School of Medicine explain social genomics – how experiences like loneliness, poverty, or feeling cut off from other people can literally change which genes switch on and off.
He describes a striking pattern he calls the "conserved transcriptional response to adversity": more inflammatory gene activity and dampened antiviral defences in people facing long-term social hardship.
As he puts it, "It’s almost as though there’s a kind of an operating system level neurobiological process going on that’s running our bodies… but it’s not terribly well synced up with our conscious mind." Host Lynne Malcolm guides the chat with clear, down-to-earth questions, keeping complex science relatable for anyone interested in mental health, chronic illness, or long-term recovery.
The episode is especially relevant if you’re rebuilding life after addiction and wondering how stress, isolation, or lack of purpose might be affecting your health under the surface. There’s genuinely hopeful news here. Long-standing, heavy loneliness seems most harmful, but the body is remarkably resilient. Changes in gene expression often settle back once life improves, and Steve highlights two powerful buffers: a strong sense of purpose and meaning, and regular contemplative or wellness practices like meditation, yoga, or Tai Chi.
These don’t magically erase adversity, but they’re linked with more "favourable gene expression profiles" even in tough conditions. You’ll also hear why nature versus nurture is now a blurred line, and how future research might use gene patterns as a kind of "molecular fingerprint" to test what lifestyle changes work best for each person.
If you’ve ever wondered whether your social connections and sense of meaning really matter for your physical health, this episode might leave you asking: what kind of life is your body quietly responding to right now?
