Numerous studies explore the correlation between social connections (friends, family, club members) and health biomarkers. These include metrics already mentioned [
Martino J et al. 2017] and more complex ones like C-reactive protein levels [
Yang YC et al. 2016], which reflect systemic inflammation.
Research, including meta-analyses [
Holt-Lunstad J et al. 2010], confirms that the quality and quantity of social ties significantly affect mortality risk—comparable to traditional health factors.
Social bonds also influence chronic disease risk, infection susceptibility [
Cohen S et al. 1997], and even pain tolerance [
Johnson K & Dunbar R 2016].
Some of the reasons behind these correlations are well understood, while others remain the subject of active scientific discussion. In any case — higher pain tolerance means longer, faster group rides!
