On Plasticity and Social Connections

Barbara Fredrickson’s op-ed titled “Your Phone vs. Your Heart” in The New York Times this weekend hits a nerve (so to speak):

In short, the more attuned to others you become, the healthier you become, and vice versa. This mutual influence also explains how a lack of positive social contact diminishes people. Your heart’s capacity for friendship also obeys the biological law of “use it or lose it.” If you don’t regularly exercise your ability to connect face to face, you’ll eventually find yourself lacking some of the basic biological capacity to do so.

The human body — and thereby our human potential — is far more plastic or amenable to change than most of us realize. The new field of social genomics, made possible by the sequencing of the human genome, tells us that the ways our and our children’s genes are expressed at the cellular level is plastic, too, responsive to habitual experiences and actions.

The gist is that by alienating away from human connection, your brain chemistry/structure changes (the concept is called plasticity). But it can be changed (for the better, in terms of how you feel) if you spend meaningful time with others. So step away from Twitter, slow down on the text messaging, and make plans to go out for dinner with a friend.
