Smartphone use could be changing shape of our skulls

Smartphones are changing the shape of our skulls. Some people spend so long looking at smartphones that a small bump is appearing above their neck. It is big enough to feel by pressing the bottom of the skull. A health scientist at a university in Australia spoke to the BBC about the discovery. He said: "I have been a [doctor] for 20 years.…In the last decade, increasingly, I have been discovering that my patients have this growth on the skull." The bump is more frequent among 18 to 30-year-olds. They spend many hours a day bent over their smartphones.

A study looked at the smartphone use of 1,200 people aged 18 to 86. The 18 to 30-year-olds were more likely to have the skull bumps. A researcher said the bumps will be more common becausewe bend our necks while looking at our phones. The skull bump could come from always bending the neck at an angle to look at digital devices. Bending our head at the same angle for a long time can strain the neck. Doctors call this strain "text neck". They also say the skull bump rarely causes health issues. They told people to change their posture if their neck becomes sore.
