iPads can be a pain in the neck

Harvard School of Public Health researchers examined the physical effects on the head, neck and shoulders of spending time staring at iPads and other tablets and found that many users are putting a lot of strain on their neck muscles.

“If you think about your position when you are hunched over looking down, your head is hanging out over space, so you are using your neck muscles to support the weight,” said Jack Dennerlein, director of the Harvard Occupational Biomechanics Laboratory, and lead author of the paper.

Researchers say it’s best to read the iPad while it’s rested at a steep angle on a table.
