CALIFORNIA WARNING HEALTH HAZARDOUS RISK WHEN USING cellphones
 Cell phone radiation and health hazards are a long-term problem that can be resolved - this is urgent enough for the California Department of Public Health to issue guidelines on how to reduce cell phone exposure for everyone. . Although phone manufacturers have suggested certain ways in cell phones such as: using hands-free options or speakers, but most people do not pay attention to the manual. Now, California has official recommendations on how to reduce the risk of harm to people not by distracting cell phones, but on user-generated radio energy.

Anxiety emerged from studies, which warned of a slightly increased risk for brain cancer and tumors of the vocal nerve and salivary glands. Others recommend lower sperm count and sperm quality in men, different effects on learning and memory, headache, and sleep effects for both sexes. However, more verification is required, and not all experts believe there is a problem with the phone.

The publication of these guidelines is in part, because University of California researcher Joel Moskowitz sued California for not giving these recommendations in the first place. Earlier this year, a management judge for his sake and the state were forced to come up with a draft. This week, they release an updated and official guide.

Mr. Moskowitz told local broadcaster KCRA after the draft was released earlier this year: "Manufacturers want you to keep your cell phone at the minimum distance from your body and you will find out what that distance is." "If you keep a mobile phone device in your body, you will exceed the safety limits provided by the Federal Communication Commission (FCC)."

Some of California's suggestions are:

• Keep the phone away from your body whenever possible. Keep your phone in a purse or briefcase, instead of in your pocket or bra.

• Reduce cell phone use when the signal is weak (i.e. the phone shows only one or two wavebars) or if you are traveling fast by car or bus because phones emit more radio frequency energy on these times.

• Reduce the use of audio or video on mobile phones, reduce downloading or uploading large files.

• Keep your phone out of bed at night, especially away from your head

• Remove your headset when you are not on a call

• Avoid products that claim to block radio frequency energy. These products may increase your exposure to radio frequencies.

California Department of Public Health Director and State Public Health Officer Karen Smith said: "Although science is still evolving, there are concerns of some public health professionals and members. of the public about long term exposure to energy emitted by cell phones ". "We know that simple steps, such as putting your phone in your pocket and getting it out of bed at night, can help reduce harm for both children and adults."

"Children and teenagers are at particular risk, because their brains are still developing and are vulnerable to the radiation emitted by cell phones," she added. "Children's brains will develop through their younger years and may be more affected by cell phone use," Smith said. "Parents should consider reducing the amount of time their children spend on cell phones and encouraging their children to use cell phones. should turn off the phone at night ".

The new recommendations might not come as a complete surprise. The World Health Organization has classified radiation from cell phones as "viable carcinogens" since 2011, and acknowledges that more research is needed, and that long-term studies are underway. While other states will follow California in making interesting guides to watch, given the potential physical health risks and well-illustrated psychological risks associated with smart phones, therefore, it may take time to cut down on the dangers of mobile phones if possible.
