Susan Pinker: why face-to-face contact matters in our digital age | Books | The Guardian: Our survival hinges on social interaction, and that is not only true of the murky evolutionary past. Over the last decade huge population studies have shown that social integration — the feeling of being part of a cohesive group — fosters immunity and resilience. How accepted and supported we feel affects the biological pathways that skew the genetic expression of a disease, while feeling isolated “leaves a loneliness imprint” on every cell, says the American social neuroscientist John Cacioppo. Women with breast cancer who have expansive, active, face-to-face social networks, for example, are four times as likely to survive their illness as women with sparser social connections. How might that work? Research led by Steve Cole at the University of California, Los Angeles shows that social contact switches on and off genes that regulate the rate of tumour growth (and the level of cancer-killing lymphocytes in our bloodstreams).
