Journal of Behavioral Addictions, 8(3), 395-403. https://doi.org/10.1556/2006.8.2019.21 Have you ever reached for your phone during a quick break, thinking it would help you recharge, or you could find out something important, only to feel drained afterwards? As cell phone addiction rises, many people frequently turn to their phones for breaks. Researchers wanted to understand how taking cell phone breaks affects energy and task performance. They had 400 participants complete a demanding task – solving anagrams on paper or a computer. Researchers randomly assigned participants to four groups: three took a break by making a shopping list on a cell phone, computer, or paper, while the fourth worked through the task without a break. Results? Taking breaks on a cell phone slowed cognitive recovery. Participants using phones performed slower and solved fewer anagrams in the second half compared to those who took breaks using other mediums or no break at all. As our cell phone addiction grows, it is critical to understand its cognitive impacts. Many think using a phone is the same as other breaks, but this study shows phones can demand more from your brain than expected. Before you pick up your phone, remember, your next break could boost your energy or drain it!
