3. Using it with a low signal
When you see a weak signal on your phone, it actually means your phone is putting out a stronger signal as a transmitter, and more energy from your cell phone means more harm to your health. Dr. Devra Davis, the author of Disconnect: The Truth About Cell Phone Radiation, What the Industry Is Doing to Hide It, and How to Protect Your Family, recommends using a landline or to keeping the phone as far away from you as possible when the signal is low. It also causes your phone to heat up which is another danger.
4. Keeping it in contact with your skin
There are several studies that focus on the link between cell phones and cancer, specifically their transmission signal that’s around 900 MHz, which makes your phone get hot. Your skin absorbs the heat easily in tiny bits every time you keep it close to your body. Although there are no other proven effects of radiofrequency radiation on the human body, we know for a fact that the absorption ratio decreases dramatically when you keep some distance between you and your phone.
Try using a headset or speakerphone while talking on your cell, to keep it from touching you and if you’re not using it, leave it far away from you for the least amount of exposure.
