A study conducted by researchers at Australia's University of the Sunshine Coast concludes that cellphones and other handheld devices are changing the human body.

An X-ray image from the study shows a neck with a bony bump at the back of the skull. The study shows that the bony bump is formed when your head is tilted down so much that you shift weight from your spine to the muscles at the back of your head, causing the bump to grow and stick out from your skull.

Dr. Ariel Goldman, an orthopedic surgeon with Northwell Health, says that while it's real, it's not necessarily something of which to be afraid.

But Goldman also says most people don't use proper posture when they're on the phone, computer, driving or doing any other repetitive activity.

There are things you can do if the bump causes you pain while using your phone: Keep your phone at eye level, maintain your posture so your chin and the middle of your nose is in line with the middle of your chest and don't look down or tilt your head.

Goldman says the bump doesn't have to be removed unless it causes pain.

The study was originally conducted in 2016 but is getting renewed attention following a BBC report on how technology is changing the human body.
