Australian scientists found young adults are more likely to have a spike-like growth on the lower end of their skull. The growth of a “external occipital protuberance” has become more frequent because we spend so much time on our phones. The growth, known as an external occipital protuberance, appears at the lower end of the skull. It’s possible that the spike comes from constantly bending one’s neck at uncomfortable angles to look at smart devices. As people hunch over their screens, they put pressure on where the neck muscles meet the skull.

The body then develops more bone layers in that area. The bony skull bump, known as an external occipital protuberance , is sometimes so large, you can feel it by pressing your fingers on the base of your skull. n a 2016 study in the Journal of Anatomy, researchers looked at the radiographs of 218 young patients, ages 18 to 30, to determine how many had these bumps. Regular spikes had to measure at least 0.2 inches (5 millimeters), and enlarged spikes measured 0.4 inches (10 mm). Luckily, these spikes rarely cause medical issues.
