Which Ear Do You Use When Taking a Call?

Really, it is your brain that makes the decision rather than which ear you favor or which hand you prefer to hold your phone with. The reason is because of the way that your ears connect to your brain.

Believe it or not, the speech center of the brain can be on either side. The fact is, however, for nearly 19 out of 20 of us, this is on the left side. Brain hemispheres coordinate with the opposite side of the body. This accounts for why the majority of people are both right handed and talk with the phone held up to their right ear.

Researchers intend to use this information in a number of ways. For example, for many years, there have been concerns over the connection between cell phone use and brain tumors. Since the majority of people hold cell phones to their right ear, you would expect more brain tumors to be focused on that side. So far, researchers are seeing that the only factor that really connects cell phone use and brain tumors is the sheer amount of phone use. Neck cancer does not seem to be related to cell phone use.

Another phenomenon that researchers are looking into is the fact that people use their right hand as well as their right ear. For a right handed person, this seems to make little sense, since they are tying up their dominant hand, which could be used for note-taking or other activities.

5,000 individuals were a part of a study that involved cell phone use and which side of the brain a person’s speech center was on. The individuals were already undergoing tests to determine the location of their speech center for one reason or another. The results were then compared to a survey in which individuals revealed which ear they usually hold their phone to. In the study, 68% percent of people who favored their right hand also favored their right ear for phone calls. For lefties, 72% stuck to their dominant side. The study didn’t just show that a person wanted to use their dominant hand, but that they wanted to use the ear the correlated with the dominant side of their brain.
