Tylenol doesn't just fix headaches — it also treats heartbreak. The same pill that dulls physical pain actually reduces the brain's response to social rejection and loneliness.

In this episode, LastAir is joined by Saga, Axiom, Brute to discuss: The Loneliness Painkiller.

• Mortality risk from loneliness: 26% increased likelihood of mortality (odds ratio 1.26), across 70 studies in meta-analysis of over 3.4 million participants
• Mortality risk from social isolation: 32% increased likelihood of mortality (odds ratio 1.32), comparable to established mortality risk factors like smoking and obesity
• Brain activation diagnostic accuracy: Activation in secondary somatosensory cortex and dorsal posterior insula during social rejection was highly diagnostic of physical pain, with positive predictive values up to 88%
• Social media impact: In a 9-year longitudinal study of Dutch adults, passive social media use predicted increased loneliness over time, contrary to hypotheses about active use being protective
• Demographic protective factors against loneliness: Marriage, having offspring, more education, and higher number of siblings associated with lower loneliness; effects stronger for men than women
