ILL EFFECTS OF CELL PHONE ON HEALTH People who use a mobile phone for hours a day are more likely to develop mouth cancer than those who do not talk on them at all.

Mobile phones use microwave radiation to communicate.These waves cause disturbance in sleep & cause difficulty in concentration.They increase the blood pressure

Mobile phones damage key brain cells and could trigger the early onset of Alzheimer’s disease.Researchers have found that radiation from mobile phone handsets damages areas of the brain associated with learning, memory and movement. 

People who used cell phones are more likely to have a temporal brain tumor on the side of the head where they held their phone.

TIPS TO REDUCE RADIATION Use a hands free set to reduce the amount of radiation.

Hold the mobile from the bottom.

Try to use the phone in an open area ,this will also reduce the radiation.

Don't talk too long on mobile phones.
