i think using mobile for lot of hours is very harmful.Before i didnt had i used to surf on the internet through my mobile it can cause pain in the hands. i also knowing talking on mobile for long time also harms a lot.
I am giving the following things just to my knowledge, where i have red some articles in the internet...which will be harmful for us, using of mobiles
1. spending lot of times on talking to somebody..
2.always using mobile without handsfree/head phones..It my directly cuz the effect to the brain, due to high radio frequency waves
3. always carry the mobile in your shirt pocket, again due to high radio frequency waves..
4. some people might talking over the mobile,while it is connected to the power point for charging...
5. If you spend more on mobile phones, they may be high chances of addiction ..it is more dangerous.. where after that you can't live without the mobiles...
6. always talk while walk instead of sitting ..It may leads to back pain...
Be careful guyz...Use the mobile in good manners..
if we talk even for 5 minutes when our mobile battery is low,it is totally hazardous.At such times,the vibrations emitted by mobiles are stronger and affect our brain strongly.
