Researchers at the University of the Sunshine Coast in Queensland, Australia, have come up with an intriguing discovering that has to do with bone growth in skulls of younger adults (aged 18-30) which they say is due to a shifting body posture resulting from excessive smartphone usage.
They also claim their study to be the first documentation of a human body physiologically adapting to modern technology in everyday life.
As heads tilt forward with eyes glued to mobile screens, weight shifts from the spine to the muscles at the back of the head.
This causes bone spurs in the connecting tendons and ligaments and is similar to how the skin thickens into a callus in response to pressure or chafing.
“The result is a hook or hornlike feature jutting out from the skill, just above the neck,”reports The Washington Post.
The researchers say that the posture resulting from excessively using smartphones is to blame for the bone-deep changes in the body. Their study has beenpublishedin Nature’s open-access Scientific Reports Journal.
What the research says
The study in question examined 1,200 X-rays of males and females between 18 and 86. It then divided the results according to age, with a decade-by-decade approach, and examined the size of the extended external occipital protuberance and how it relates to gender and the degree of forward head protraction, a term used to describe how far forward your head rests.
The unusual growth is present in many of our skulls and isn’t dangerous or particularly noteworthy on its own. In fact, it can happen in other locations in the body as you age.
