You may be hunched over your phone right now, worrying about reports that young people are growing horns on their skulls from spending too much time hunched over smartphones.

O. K., cellphones are making us rude and inattentive, but medical experts don’t totally buy the idea that technology is also warping our skeletons.

The area of concern is the back of the skull where it meets the neck, a place that already has a slight, normal bump that’s easy to feel. Two Australian researchers say they have found enlargements, or bone spurs in that region, anywhere from a third of an inch to more than an inch long.

Recent articles by the BBC and the Washington Post have cited a 2018 study in the journal Scientific Reports saying that these bone growths have been turning up more often than expected in people aged 18 to 30. The study suggests that “sustained aberrant postures associated with the emergence and extensive use of hand-held contemporary technologies, such as smartphones and tablets,” are to blame. The authors are a chiropractor, David Shahar, and an associate professor of biomechanics, Mark G.L. Sayers, both from the University of the Sunshine Coast in Queensland, Australia.
