Teeth and Jaw
If the idea of developing a smartphone habit is making you grit your teeth with dread, Tel Aviv University research has provided convincing evidence that many, if not most, heavy smartphone users can relate. The School of Dental Medicine at Tel Aviv University was in a unique position to test the theory. It was not difficult to find a sizable study sample of non-Smartphone users as many ultraorthodox Jews in Israel use more basic cell phones without access to social media sites.
According to a survey with 600 participants, smartphone users reported having teeth grinding at a rate of 45% compared to 14% of religious people, a difference of more than 200%. Furthermore, 29% of smartphone users claimed that it was bad enough for them to experience visible jaw pain, compared to only 14% of orthodox people. The injury was frequently severe enough to cause jaw joint damage. Toplist doesn't usually advise audience on matters of faith, but it is worth mentioning that many of the people in this group seemed to find orthodox Judaism to be a source of stress alleviation.
