Answering the phone with your left ear is less likely to cause a brain tumor

There is a saying on Weibo that you should not answer the phone with your right ear, because the right ear is closer to the brain and the right brain is more important. The radiation from the mobile phone when answering the phone will damage the brain, so it is safer to answer the phone with your left ear.

In this regard, experts said that this statement is completely unfounded. As long as the call time is not long, it does not matter which ear you use. If you are on the phone for a long time, it is best to alternate between the left and right ears.

Xu Lanping, chief physician of the Department of Neurology at Beijing Chaoyang Hospital, introduced that the human brain is indeed divided into left and right brains. The left brain is the logical brain, responsible for creativity, language, emotion, etc.; the right brain is the image brain, responsible for spatial imagination and emotion, and is responsible for music, art and spatial recognition. So in terms of brain function, both the left and right brain are equally important.

In addition, the left and right ears and the left and right brain are symmetrically distributed, and the distance between the left and right ears and the brain is the same. This is common sense, and there is no such thing as "the right ear is closer to the brain." Even though mobile phones have radiation, theoretically answering the phone with either ear will cause the same amount of damage to the brain.

So will the radiation from mobile phones when answering the phone really cause brain cancer as rumored? Xu Lanping introduced that the brain cancer that ordinary people refer to is generally glioma. Data in recent years show that the incidence of glioma is indeed on the rise, and there are indeed reports of this abroad. However, this is by no means a single problem of mobile phone radiation. The pathogenesis of brain cancer is complex, and genetic genes and environmental pollution are all possible factors. The medical community has not yet reached a consensus on whether mobile phone use is the cause of brain cancer.

However, this does not mean that you can chat on the phone without restraint. Professor Wang Wuqing, chief physician of the Otolaryngology Hospital affiliated to Fudan University, said that answering the phone for a long time can cause obvious damage to hearing. In addition, answering the phone for a long time, the phone heating up and being close to the face, coupled with bacteria on the body, can cause facial dermatitis.

Experts say that mobile phone radiation does exist. In normal times, we should try to use our mobile phones as little as possible, control the call time, answer the phone for a long time, alternate between the left and right ears, and it is best to use a headphone cable. When using headphones, we need to pay attention to the volume. When sleeping, do not place your phone next to your pillow, and try not to place it close to your head or heart.
