Do you ever do homework while listening to music，or watch TV while texting friend? It may seem like an obvious question since most of us multitask all the time．

But according to a recent study published in PLOS ONE，using a number of media devices at the same time could be changing our brains．

Researchers first asked 75 adults about how often they spent time multitasking between different kinds of media． 36 Those who reported heavier media multitasking had less gray matter in their brains．Gray matter is the part of the brain that helps to deal with information and control emotions． 37 We can’t be sure，according to researchers．They say that the results only show a link．They are unsure whether multitasking reduces gray matter．

“Media multitasking is becoming more popular in our lives and there is increasing concern about its influence on our well-being，”said British scientist Kep Kee Loh，who directed the study．Loh says that more study is needed to support the idea that our behaviors are changing our brains．38 In 2012，a study by Michigan State University in the US found that people using several media devices at the same time were more likely to be depressed．

39 But no matter what，you should consider limiting yourself to one screen at a time，the Huffington Post reported．Multitasking doesn’t actually work if you are trying to be more efficient．You’re going from one action to another instead of truly doing two things at a time． 40 Once you’ve slowed down，it can be hard to pick up where you left off．
