The Claim

In individuals aged 65 and older, greater social engagement is associated with lower subsequent levels of C-reactive protein, and higher levels of C-reactive protein are associated with reduced social engagement over time, indicating a reciprocal association between social activity and systemic inflammation.

In plain English

In people aged 65 and older, being more socially active is linked to lower levels of a marker of inflammation called C-reactive protein, and higher levels of this marker are linked to less social activity over time, suggesting a two-way relationship between social behavior and inflammation.

See the scientific wording

Greater social engagement in older adults is associated with lower subsequent levels of C-reactive protein (CRP), and higher CRP is associated with reduced social engagement over time, indicating a reciprocal relationship between social activity and systemic inflammation in individuals aged 65 and older.

Why this might work

When older adults spend time with others, their bodies produce less of the stress hormone cortisol, which in turn reduces the release of inflammatory chemicals into the blood. When there’s more inflammation in the blood, it makes people feel tired or unwell, so they’re less likely to want to go out and be social.

1 study

  1. Study: The reciprocal associations between social deficits, social engagement, and inflammation: Longitudinal evidence comparing venous blood samples and dried blood spots and mapping the modifying role of phenotypic and genotypic depression.

    When older people spend more time with others, their body’s inflammation levels go down—and when inflammation is high, they tend to socialize less. It’s a two-way street: being social helps you stay healthier, and being less inflamed helps you stay social.
