A very harmful habit is to sleep with the mobile phone close to the head. Researchers in two separate studies in China and the United States have shown that the constant use of mobile phones, especially when sleeping at night, is extremely dangerous. This habit can be fatal.
According to a report published by the World Health Organization, keeping a mobile phone close to the head causes the development of cells to be affected by the effects of radiation on the body. As a result, the risk of getting various cancers increases drastically.
Another thing is that many people fall asleep with the phone close to their head with an alarm on their mobile phone to wake up at a certain time in the morning. From setting the alarm on the mobile until we turn it off, there is a radio transmission from the phone. In other words, invisible waves start coming out of the body of the mobile which causes severe damage to the body and brain. If the phone is low charge again or someone falls asleep while charged, then there is no point!
According to researchers, if the mobile phone is kept at least 3 feet away from the body during sleep, the risk of damage is greatly reduced.  Therefore, it is better to sleep away. Besides, none of us use WhatsApp or peek at social media. That's why sleeping with the phone away is not a problem, but good for the body. Remember one thing, everything is only if you are healthy.
