A report from The Washington Post discovered that looking down at phones could cause an abnormal bone growth that resembles a horn at the base of the neck of many young people.
In a 2016 study, 41% of the 218 16- to 30-year-olds studied had lumps on the backs of their necks that research suggests is caused by looking down — like at a phone — for extended periods of time.
It's important, however, to note that correlation does not always equal causation, and the study has some questionable tactics for getting to this conclusion. For one, the researchers didn't study the subject's phone use, according to Business Insider's counter article.
So before you start panicking and feeling the back of your neck for a bump, relax. Ultimately, this study hypothesized that the "horn" came from poor posture and not the evils of technology. And, according to a statement, one of the author's of the study shared that the issue can be corrected quite simply.
There are plenty of negative psychological side effects already proven with extended phone use that haven't deterred many people from continuing to stare down at screens. Perhaps the fear of a sprouting horn is just what it'll take.
