NPR – “Stress is part of the human condition, unavoidable and even necessary to a degree. But too much stress can be toxic — even disabling. And there’s a lot of toxic stress out there A national poll done by NPR with our partners at the Robert Wood Johnson Foundation and the Harvard School of Public Health finds that more than 1 in every 4 Americans say they had a great deal of stress in the previous month. And half of all adults say they experienced a major stressful event in the past year. That works out to more than 115 million people. As big as that number is, it’s just the tip of the stress iceberg, says Princeton University psychologist Eldar Shafir. “Everything I know suggests that this is a pretty massive underestimate,” Shafir tells Shots. That’s because our poll captures only the stress that people are conscious of. Shafir’s work and that of others shows there’s a lot of stress people don’t even realize they have. And this “hidden” stress can reduce our capacity to juggle all the big and little problems life sends our way.”
