短信脖 Text neck
As we tap away for extended periods of texting, browsing and tweeting, we could be putting ourselves at risk of getting text neck.
A newly coined condition – text neck – reveals that slumping over your mobile phone, tablets or other hand-held device for hours on end heaps so much pressure on your spine, that we're giving ourselves long-lasting back problems.
The root of the problem appears to be our heads which, weighing in at 4–5 kilos, are harder to support when we bend over – a little like carrying a weight at arm's length rather than closer to the body.
Text neck can lead to wear-and-tear on the spine.
