Health Tips for Mobile Phone Users

Here are some some health tips for mobile users. These are the precautionary guidelines as released by Department of Telecommunication (DOT) India.

Since people are more addicted to mobiles and some people may not know its harmful effects to our body, here are some helpful tips while using your mobile.
  • Keep distance while answering a call by hold the cell phone away from body to the extent possible.
  • Use a headset (wired or Bluetooth) to keep the handset away from your head.
  • Do not press the phone handset against your head. Radio Frequency (RF) energy is inversely proportional to the square of the distance from the source, being very close increases energy absorption much more.
  • Limit the length of mobile calls.
  • Use text as compared to voice wherever possible.
  • Put the cell phone on speaker mode.
  • If the radio signal is weak, a mobile phone will increase its transmission power. Find a strong signal and avoid movement. Use your phone where reception is good.
  • Metal and water are good conductors of radio waves so avoid using a mobile phone while wearing metal framed glasses or having wet hair.
  • Let the call connect before putting the handset on your ear or start speaking and listening. A mobile phone first makes the communication at higher power and then reduces power to an adequate level. More power is radiated during call connecting time.
  • If you have a choice, use a landline (wired) phone, not a mobile phone.
  • When your phone is ON, don't carry it in chest/breast or pants pocket.
  • When a mobile phone is ON, it automatically transmits at high power every one or two minutes to check (poll) the network.
  • Reduce mobile phone use by children as a younger person will likely have a longer lifetime exposure to radiation from cell phones.
  • People having active medical implants should preferably keep the cell phone at least 15 cm away from the implant.
  • While Purchasing a Mobile Handset check the SAR value of the mobile phone. It can be searched on internet if its model number & make is known. According to DOT mobile handsets shall comply with the SAR values of 1.6 W/kg averaged over 1 gram of human tissue w.e.f. 1st September 2012.

The mobile handsets with existing designs which are compliant with 2.0 W/kg averaged over 10 gram of human tissue, continue to co-exist up to 31st August 2013. From 1st September 2013, only the mobile handsets with revised SAR value of 1.6 W/kg would be permitted to be manufactured or imported in India.

Apart from the above tips I will like to add two more tips.

Answer the phone by left ear.

When the battery is low to the last bar, do not try to make or receive any call because radiation at this time is 1000 times more than the normal.

Hope the tips will be helpful for you.
