Excessive use of smartphones has led to an increase in young people developing "horn" bone growth in the back of the skull, according to research.
These bone sports, also known as insects, are abnormal lumbar protrusions that can form when attaching a tendon or ligament.
The study by researchers at the University of the Sunshine Coast in Queensland, Australia, included more than 200 X-rays of 18- to 30-year-olds.
He found that 41% had developed a hollow piece of 10 to 30 millimeters in the back of their skull.
Further trials, including MRI and blood tests, precluded the possibility that the increases were due to genetic factors or inflammation.
Interstices usually appear in the elderly with a bad posture and are the bone's response to anxiety, according to the study.
Researchers have explained that in this case, abnormal growths appear to have been caused by long-term stress on the skeleton as the head shifts forward while we use smartphones for extended periods.
"We assume that the prolonged increase in load in this muscle buoyancy is due to the weight of the head shifting forward using modern technologies for long periods of time," said Dr. David Shahar, who completed his doctorate at USC at the time that of the study.
"Moving the head forward results in the transfer of the head's weight from the bones of the spine to the muscles at the back of the throat and the head.
"Increased load requires remodeling in both the tendon and the bony ends of the ligament. The tendon footprint in the bone becomes wider to distribute the load on a larger surface of the bone."
While bone growth is not a problem in itself, it is an indication of a lasting horrible attitude that can cause chronic pain in the long term, according to the researchers.
Dr Shahar said the findings highlighted the need to prevent prevention by modifying attitudes when using handheld technologies.
The research was published in 2016, but re-appeared after a BBC article published last week, cited as an example of how the human skeleton evolves.
Some industry commentators have questioned the study, however, noting that there is nothing to prove the relationship between phone use and the size of these so-called "horns."
Also, there is no way to compare the prevalence of these bone augmentations with the pre-smartphone, so it's likely that it's just more common than previously thought.
There are already known medical illnesses associated with excessive use of computers and smartphones, such as carpal tunnel syndrome and eye strain.
There is also a condition known as "tech neck", which causes the neck to reverse its curve from a curve back to a forward curve, creating tension in both your neck and your spine.
If you are worried about the consequences of using prologued technologies for your health, you should talk to your GP and examine your attitude and mitigate your screen time.
