A large majority of the world's 3.4 billion smartphone users are putting their necks at risk every time they send a text, scientists say.
'Text neck,' as it is colloquially called, places stress on the spine and alters the neck's natural curve, increasing the likelihood of associated soft tissue discomfort. The study, published in the journal PLOS One, highlights the high ergonomic risks to smartphone users, particularly young people, who are experiencing neck pain earlier than previous generations.
