The electro-magnetic energy (EMF) is dangerous for our brain when we make a call or receiving a call.Excessive electro-magnetic radiation could damage our brain for long period of use.If you use cell phone often,you need to use hands free equipment.This equipment help you to use your cell phone far from your ear and prevent electro-magnetic radiation directly to your brain.
