Researchers say the effort of shouting the word ‘eina’ interferes with pain messages traveling to the brain.
Biologists previously suggested we have evolved to spontaneously shout out in order to warn others of danger
But the new research indicates that we may actually do so to distract ourselves from the feeling of pain.
And the expressions of pain are shared across language barriers.
One assumes using expletives also works...The study is published in the aptly named Journal Of Pain.
