The development of the growths may be attributed to extensive screen-time, the researchers said. Sustained “forward head flexion,” or bending the head down, and poor posture could be the reasons for these physiological changes, they hypothesized.

A BBC article last week on how the human body is changing with technology use brought new attention to the study.
