手机与癌症有关：现在要做的12种健康改变

9.    Spend even less time on your PDA. Wireless devices such as the BlackBerry, iPhone, and Treo produce higher emissions than cell phones because they rely on the energy from batteries to power up things like e-mail, Internet connections and color display.
9. 少用掌上电脑。 如黑莓，iPhone和Treo这些无线装置，比一般手机产生的辐射更高，因为它们依靠电池增加如邮件，连接网络和彩色显示这些能量消耗。

10.    Dial, then stretch. Don't place the cell phone on your ear while your call is connecting -- that's the time the phone is sending out its strongest signal.
10. 拨号，然后拿开。 当通话在接通的时候不要把手机放在耳边——那个时候手机发出的信号最强。

11.    Get it out of your pocket. A recent study found that men who carried their cells in their pockets had 25 percent lower sperm counts when compared to another group that didn't carry a cell. Different parts of the body absorb radiation in different intensities, and testicular tissue may be more vulnerable.
11. 不要把手机放在口袋里。 最近一项研究发现，跟没有把手机放在口袋的男性相比，把手机放在口袋里的人精子数少了25%。身体不同部位吸收辐射强度不同，而睾丸是比较容易受到攻击的。

12.    Keep the cell out of the bedroom. Specifically, don't sleep with your cell near your head. Remember, electromagnetic fields can reduce your body's production of melatonin and with it a powerful free radical scavenger that can protect your cells from the DNA damage that can lead to cancer and other disease.
12. 把手机放在卧室外。 尤其是不要把手机放在靠近头部的地方睡觉。记住，电磁场会减少你体内褪黑激素的产生，褪黑激素是一种强大的自由基清除剂，可以保护细胞免受由于DNA破坏引发的癌症和其他疾病。
