The toxic trio of smoking, sitting, and sugar are frequently vilified as health hazards. But when it comes to brain health, there’s one thing worse than these three combined: chronic social isolation.
A 2015 study by the University of Connecticut finds that “isolation is a major source of psychosocial stress and is associated with an increased prevalence of vascular and neurological diseases.” Loneliness undermines three major biological systems, including the immune system, that protect and support brain health.
Conversely, prosocial hormones such as oxytocin and serotonin reduce inflammation and pain. A recent study by AARP found a link between social engagement and brain health for seniors; unfortunately, 40% of adults over 40 say they lack social connections.
Eye contact, fun, listening, sharing, smiles, speaking, touch, and trust forge strong social bonds. As far as our brains are concerned, love is the best medicine and friends are sweeter than sugar!
