The International Agency of Research on Cancer (IHRC) in 2011, issued a warning that "cell phones might possibly cause brain cancer." Mobile phones emits radiation. Although radiation is useful in medical field for treating and diagnosing some illnesses, it harmful effect shouldn't be overlooked. Studies have shown that prolong exposure to radiation can cause cancer. Women who are in the habit of keeping their phone in their bra to prevent theft can develop breast cancer. Men who also keep their cell phone constantly in their trouser pocket increases the risk of developing testicular cancer.
Knowing this, what you do think will happen if one continue to expose the brain to radiation from the cell phone by sleeping with it under the pillow. Prolong exposure of the brain to radiation can cause brain tumour and brain cancer. It can prevent optimal sleep, cause memory impairment and learning disorder. To prevent yourself from these health problems, you should never sleep with your cell phone under your pillow. If you must do, it is either you switch it off, put it in flight mode or place it about 20cm away from your bed. Do you think you can stay without your cell phone at night?
