According to statistics, there are around 1.9 billion cellular phone users all over the world, with a great part of the users in the U.S. alone. Scientists fear that cellular phone radiation can cause diseases including high blood pressure, headaches, brain tumors, Alzheimer’s and even cancer, and more. Yet due to the cumulative effects of cell phone use not everyone is fully aware of the those harms.

Before it is too late, cell phone owners should take some action to reduce radiation exposure to the minimum degree. Here are some general tips:

1. Keep the chance to be exposed to cell phones to the smallest. This means that you had better keep calls short, do your best to avoid chats that last for long time. A simply two-minute call has the power to alter the regular electrical state of the brain for at least one hour afterwards.

Children should be limited to use cell phones.

It is best to keep the phone away from your body when you do not use it. Some mobile phone users would like to put the phones in trousers pockets while in use. The lower body area absorbs even more radiation than the upper part.

2. If you want to use earphones, choose airtube headsets rather than wired ones. The wire of the earphone not only transmits cell phone radiation to the head but also works as an antenna which attracts EMFs (electromagnetic fields) from its neighbourhood. If you are using your cell phone without a earphone, wait for the call to connect before placing it close to your ear.

3. When buying from cell phone wholesale providers or retailers, Select those with lower SAR (Specific Absorption Rate). Note the SAR number listed in the instruction book. The lower the SAR value the better.

Avoid calling in enclosed metal spaces such as cars or elevators—the radiation is stronger.
