In an article that has wide-ranging policy implications, Moises Velasquez-Manoff, science writer, tells us about the costs to society from high stress to those less fortunate:
Although professionals may bemoan their long work hours and high-pressure careers, really, there's stress, and then there's Stress with a capital "S." The former can be considered a manageable if unpleasant part of life; in the right amount, it may even strengthen one’s mettle. The latter kills.What's the difference? Scientists have settled on an oddly subjective explanation: the more helpless one feels when facing a given stressor, they argue, the more toxic that stressor's effects.
That sense of control tends to decline as one descends the socioeconomic ladder, with potentially grave consequences. Those on the bottom are more than three times as likely to die prematurely as those at the top. They're also more likely to suffer from depression, heart disease and diabetes. Perhaps most devastating, the stress of poverty early in life can have consequences that last into adulthood.
"Early-life stress and the scar tissue that it leaves, with every passing bit of aging, gets harder and harder to reverse," says Robert Sapolsky, a neurobiologist at Stanford. "You're never out of luck in terms of interventions, but the longer you wait, the more work you've got on your hands."
This is the money quote, though:
"You don't need a neuroscientist to tell you that less stress, more education, more support of all types for young families are needed," Dr. Farah told me in an e-mail. "But seeing an image of the brain with specific regions highlighted where financial disadvantage results in less growth reframes the problems of childhood poverty as a public health issue, not just an equal opportunity issue."
Indeed...this is a public health issue with the most insidious of side effects.
