A new study carried out at Tel Aviv University’s Maurice and Gabriela Goldschleger School of Dental Medicine has found that the excessive use of smartphones and social media can lead to problems sleeping, drowsiness and fatigue during the day, teeth-grinding, and pain in the mouth muscles and jaws. The study was conducted as part of Dr. Yitzhak Hochhauser's dissertation and was led by Dr. Alona Amudi-Perlman, Dr. Pessia Friedman-Rubin, Prof. Ilana Eli, and Prof. Ephraim Winocur. The study will soon be published in the journal Quintessence International.

Dr. Friedman-Rubin and Prof. Eli explain that “In today's day and age people live with a sense of FOMO (fear of missing out) and so they want to stay constantly updated and know 'what's new' every moment. This need naturally creates a growing dependence on cell phones, which leads to feelings of stress and anxiety - 'someone might write something on social media and I’ll miss it and not be in the loop.'”
In the study, the researchers compared different groups (from a total of about 600 participants): a group of secular people (smartphone users) and a group of Charedim (most of whom use a “kosher” phone without an Internet connection). Study respondents were asked to address a number of aspects that typify overuse of the phone, including feelings of stress and tension throughout the day, a tendency to wake up at night, a need to be available to the cell phone, teeth-grinding and jaw pain.

The findings of the study are clear: 54% of secular smartphone users have a moderate to high incidence of night wakings, compared with only 20% among the Charedim. In addition, half of the secular respondents (50%) feel a moderate to high level of stress due to the cell phone, compared to only 22% among the Charedim. The disparities between the groups are also reflected in the question of how available they feel they need to be to their mobile devices - 45% of the secular respondents answered that they had a moderate to high need to be available to their phones, compared to only 20% in the Charedi group.
