Strong social connections reduce chronic stress, loneliness, and allostatic load by buffering against stressors and lowering cortisol levels. This attenuates systemic inflammation, promotes mental/cognitive resilience, and encourages healthy longevity-associated behaviors, collectively reducing all-cause mortality risk.
