If you keep your phone under your pillow, you must read this.

First, keeping the phone under the pillow or on the edge of the bed is at risk of keeping you awake for a long time. Cell phones emit a blue light, which through neurons signals the brain that it is time to wake up. Therefore, it is recommended that at least two hours before bedtime, you should not keep the key burning or have its light out.

The other and most important reason is scientific evidence, which has shown that mobile phones cause cancer because of the rays they distribute, which are perceived as carcinogenic by the International Cancer Research Agency ( IARC, Agency for Research on Cancer. For this reason many health experts recommend keeping the telephone as far away from the head.

They also recommend that you usually wear earphones in your ear so that your ear is not tied directly to the phone.

So, as far off as the phone is concerned at night. Get him off the pillow. Despite their studies and results on the long - term effects of wearing a telephone to the head, doctors recommend preventing risks.

If you don't have any other place to keep the phone at night, a nearby comedy or a shelf, leave it on the floor, next to the bed, with high volume so you can hear the bell.
