New Delhi . The use of Smaartaphon has become necessary for everyone. It has become a need for daily life. In the last few years, many types of studies have come out about the use of phone. Someone said that the use of the phone can cause cancer, then someone tells that there is a big threat to animals and birds including humans. Everyone knows that the phone has a bad effect on the eyes.

But, in the use of the phone, the eyes as well as the ears are also used a lot. Perhaps your attention has never gone to this, but some researchers in the world are trying to find out which ear (left or right) should be used to listen to the phone.

Most people use this ear
Most people use right ear to talk on the phone. According to a research, listening to the phone from the right ear affects the straight mind, which can disturb you on small things. According to research, when we use the ear to talk on the phone, the radiation emanating from it affects the brain. Therefore, while talking on the phone, left ear should also be used.

Blood-brain barrier reaches damage
However, to prove whether it is safe to use left ear for phone calls or right ear, there is no adequate evidence. A study by Finland Scientist and Nuclear Safety Authority said that when our cells come in contact with the phone, it causes damage to the blood-brain barrier. Blood-brain barrier in human body is also known as a safety barrier. It prevents the dangerous substances of blood from entering the brain. However, this study could not explain which ear should be used while talking on the phone.

Which ear should be used
A study published in the journal of the American Medical Association states that about 80 percent of people use their right ear while calling on the phone, because the left part of our brain is more active. While talking on the phone, it is important for you to keep changing the phone from one ear to another. Both ears should always be used to talk on the phone.
