Detroit. About 70 per cent of people hold their cellphone to the ear on
the same side as their dominant hand, a new study finds.Left-brain
thinkers are more likely to use their right hand for writing and other
everyday tasks. They’re also more likely to hold their cellphone to
their right ear, even though there’s no difference in hearing between
their right and left ears.The reverse is true for people who are
left-handed and right-brain dominant, according to the study by
researchers at Henry Ford Hospital in Detroit.
Their online survey of more than 700 people found that 68 per cent of right-handed people said they held their cellphone to their right ear, while 25 per cent used the left ear, and 7 per cent used both ears.
Among left-handed people, 72 per cent said they held their cellphone to their left ear, 23 per cent used their right ear, and 5 per cent used both ears. The study was presented at a meeting of the Association for Research in Otolaryngology in San Diego.
“Our findings have several implications, especially for mapping the language center of the brain,” Dr Michael Seidman, director of the division of otologic and neurotologic surgery in the department of otolaryngology-head and neck surgery, said in a Henry Ford Health System news release.
The findings also suggest that there’s no link between cellphone use and brain, and head and neck tumors, according to Seidman.If there were a connection, far more people would be diagnosed on the right side of their brain, head and neck because most people are right-handed and hold their cellphones to their right ear, he said.
Because this study was presented at a medical meeting, the data and conclusions should be viewed as preliminary until published in a peer-reviewed journal. (Agencies)
