Sleeping close to to your phone results in infertility, cancer research states...

The California Department of Health, United States (U.S.), warned that people need to keep their cell phones several feet away from them to reduce radiation exposure and health risks.

California released guidance for reducing exposure to cell phone radiation on Thursday, amid mounting evidence that cell phone use may be linked to cancer, attention, mental health and reproductive health issues.

Cell phones transmit information using low frequency radio signals, which may expose us to unhealthy radiation, especially when streaming or downloading large files.

Research has not been able to prove definitively that cell phone radiation is dangerous, but there have been enough studies linking the two to warrant caution, especially for children, according to the health department press release.

The state wide notice comes after several cities, including Berkeley and San Francisco, issued local warnings that their citizens should make some Californiabetween their phones and their bodies.

The radiofrequency (RF) energy cell phones use to transmit information are at the bottom of the radiation totem poll, but research suggests that our frequent, close-range exposure to cell phones may be enough to endanger us.

Meanwhile, new research has concluded that nearly 40 per cent of cancer deaths could be prevented with eight simple lifestyle changes.

Quitting smoking, eating healthier and boozing less would help stop the disease, which claims 8.2 million lives worldwide each year.

Scientists suggest those three habits can be blamed for 30.4 per cent of all cancer deaths, around 2.5 million – with tobacco proving the biggest burden.

Five other habits, including excessive Ultra Violet (U.V.) radiation, obesity and not exercising enough can be blamed for a further 14.4 per cent of deaths – 1.2 million lives.

Also, a father-of-two who was given weeks to live has revealed he beat stage 4 colorectal cancer after switching to a vegan diet.

Rob Mooberry, now 43, told Daily Mail UK Online he was hospitalized with a perforated colon in July 2012, and scans revealed he had cancer which had spread to his bowels, lymph nodes and liver.

Doctors said the Las Vegas bartender would need a colostomy bag put in, followed by an ileostomy, then two bouts of chemotherapy and radiation therapy.

However, after the surgeries and the first round, with his cancer downgraded to stage 3A, he said he couldn’t take it any more and needed some time to detox his body of the chemicals before starting more treatment.

In November 2012, he started a plant-based diet, alkaline diet – akin to that of Tom Brady – with his vegetarian wife Amanda, now 39, following research that showed sugars and processed foods fueled tumors.

When it came to his next scan in early 2013, the cancer had shrunk by almost 80 percent.

Now he is celebrating five years cancer-free, raising 20-month-old twins, and running a small cancer charity on the side of his bar-tending to help other sufferers afford pipe dreams – and his story has gone viral, after it was tweeted by country star Tim McGraw.

“Keeping a phone directly on the body has never been a good idea,” says Dr. Devra Davis of the Environmental Health Trust.

In fact, cell phone makers themselves seem to agree. Apple, for example, includes an ‘RF exposure’ notice in the iPhone’s settings.

The notice explains that the iPhone’s RF emissions were tested at 5 mm – about the thickness of a fine point pen – from the body, and fall within the US standards of safety.

But it also includes advice for reducing exposure – not unlike California’s new guidance – by using speakerphone or hands free accessories.

“Most people are not aware that there is a clear warning to keep the phone off the body embedded in the phone,” says Davis.

This is particularly worrisome because most parents aren’t aware of these warnings are not managing their children’s exposure to phones.
