So much of modern medicine exists because of the work of women whose names we don’t hear often enough.

Behind discoveries in genetics, cancer research, immunology, and infectious disease are scientists who spent years asking difficult questions and pushing forward when answers weren’t obvious.

These women represent something powerful.

Happy International Women’s Day.

We tend to think of friendship as emotional support.

But the data suggests it is much more than that.
Social connection appears to influence inflammatory signalling, cardiovascular risk, and overall survival.
In a study by Friedman et al. (2005), women with lower social integration had significantly higher serum IL-6 levels. They had nearly 2-fold higher odds of elevated IL-6 compared to women with stronger social ties.
IL-6 is a pro-inflammatory cytokine associated with cardiovascular disease, sarcopenia, and increased mortality risk.

Loucks et al. (2006) found similar findings with CRP. Women with lower social integration had significantly higher CRP levels, and those in the lowest quartile of social connection had higher odds of CRP >3 mg/L — a recognized cardiovascular risk threshold.

Mechanistically, social connection appears to buffer stress biology. Supportive relationships reduce HPA-axis activation, modulate cortisol, improve autonomic balance, and are associated with lower inflammatory gene expression.
Chronic inflammation is a driver of cardiovascular disease, metabolic dysfunction, immune dysregulation, and accelerated aging.

Which means this isn’t just about feeling connected.
It’s about regulating biology.
