"Eighty percent of us seem to have it. I broke the story about it in early 2008 on the Huffington Post, and called the phenomenon, "email apnea." Later in 2008, in talks and interviews, I referred to it interchangeably as "email apnea" and also, as "screen apnea."
Definition: Shallow breathing or breath holding while doing email, or while working or playing in front of a screen.
While we have a greater tendency toward email apnea or screen apnea, while doing email and texting on laptops and smartphones, we are at risk for breath holding or shallow breathing in front of any screen, any time. Not only does this increase stress levels, it impacts our attitude, our sense of emotional well-being, and our ability to work effectively."
