The term 'text neck' refers to neck pain caused by prolonged smartphone use, with studies indicating a significant percentage of users experience discomfort. However, Professor Jan Hartvigsen argues that 'text neck' is not a new medical condition but rather a buzzword, with weak evidence supporting its existence. He emphasizes that neck pain is multifactorial and not solely due to phone use, suggesting that regular breaks and an active lifestyle can help alleviate discomfort.
