Cellphones help us easily find people anywhere at any time. However, using cellphones too often may cause cancer. It’s reported that people who used a cellphone for ten years or more were more likely to get brain cancer.

The suggestions below may help you reduce the risk(风险) of cancer:

When using your cellphone, try to keep it away from your body as much as possible. Don’t put it under your pillow(枕头) or on a bedside table when you sleep.

When you’re on the cellphone, use the speaker. In this way, you have just 1/100th of the contact with radiation you have when you hold it to your ear. An earphone is also a good idea.

Try to keep your conversations short. If you need to talk longer, use an ordinary phone instead.

Change ears when you’re using your cellphone. Before putting it to your ear, wait until the person you are calling picks up the phone.

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.

Do not use your cellphone when the signal is weak or when moving at a high speed, for example in a car or train. At high speeds your phone is trying to pick up signals, and this increases the radiation it gives out.
