Cell phones help us easily find people anywhere at any time. A cell phone can include many things, such as games, music and internet access. Today, 4.6 billion people around the world have cell phones, according to CBS news.

However, cell phones may cause cancer, according to the World Health Organization. In a 2010 study, people who used a cell phone for 10 years or more were more than two times as likely to get brain cancer, according to CNN.

These suggestions may help you reduce your risk of cancer:

1.Use a headset or speaker

Headsets give out much less radiation than phones. Some wireless headsets give out low-level radiation. However, you should take it off your ear when you’re not talking to anyone. Using your phone with a speaker will also make it safer.

2.Listen more, talk less

Your phone gives out radiation when you talk or text, but not when you’re listening or getting messages. Listening more and talking less can lower the risk of cancer.

3.Hold the phone away from your body

Hold the phone away from your body when you’re talking, not against your ear. Also, don’t keep it in your pocket.

4.Choose texting over talking

Phones emit less radiation to send texts than to carry a person’s voice. Texting also keeps radiation away from your head.

5.Poor signal? Stay off the phone

Fewer signal bars on your phone mean that the phone needs to give out more radiation to work. Make and take calls when your phone has a strong signal.
