People have many different ways to relax during break time at work or school. Smartphones are probably the number one choice for a quick mental vacation. Although it might seem like a good time, looking at your cellphone may harm your mental power, according to a recent psychological study from Rutgers University in the United States.
For the study, more than 400 students were asked to finish a set of 20 word puzzles. Halfway through the task, the students were divided into three groups. Group one was allowed to take a break and use cellphones to buy things online. Group two was asked to have a rest and buy things using a computer. The last group didn’t take any break at all.
Interestingly, the group that used their cellphones during the break went back to work feeling the most tired and did not want to continue. They also had the hardest time solving the remaining word puzzles. The cellphone group took 19 percent longer to finish the rest of the task, and solved 22 percent fewer problems than those in the other break conditions combined.
Terri Kurtzberg, co-author of the study, explained that they assumed looking at cellphones during a break would be no different from any other break---but instead, the phone may increase levels of distraction that make it difficult to pay attention to work tasks.
“Cellphones may have this effect because even just seeing your phone remind you of checking messages, connecting with people and more, in ways that are different from how we use other screens like computers, and laptops,” Kurtzberg told Science Daily.
So, during your next break, try putting your smartphone away. Go out for a walk, get to know your classmates or even take a little sleep. You may be surprised by the results!
