“…Yet carefully controlled epidemiological studies reveal that the effects of
close social relationships on health have an order of magnitude comparable to or greater
than that of such well-established risk factors as smoking, alcohol consumption,
obesity, and physical inactivity (e.g., Holt-Lunstad,
Smith, & Layton, 2010). Throughout adulthood, including later life,
being socially integrated and having access to social support are related to better
physical health, including reduced risks for infectious illness, cardiovascular disease,
overall cognitive and physical decline, and both cancer-specific and overall mortality
(e.g., Cohen & Janicki-Deverts, 2009;
Crittenden et al, 2014; Uchino, 2009). Conversely, being socially isolated and
feeling lonely are related to worse physical and cognitive functioning (Shankar, Hamer, McMunn & Steptoe, 2013) and earlier
mortality (Steptoe, Shankar, Demakakos, &
Wardle, 2013).…”
