California Department of Health advice: Stop putting your phone close while you sleep to avoid infertility and cancer

This is the conclusion given in the guidelines of the California Department of Health, USA.

Is there any connection between phone waves and cancer - this is the topic that has been debated for decades.

In May 2016, a study over 30 years in Australia has officially concluded that phone waves cannot cause, but that is not enough to convince all to believe in the harmlessness of mobile phones. .

And recently, the California Department of Health (USA) has published a guide. It offers advice that people need to keep the phone away while sleeping, to minimize exposure to harmful radiation. In addition, the text also emphasizes that phone waves can cause cancer, psychological disorders, and infertility.

It is known that the phone uses radio waves - a very long wavelength wave in the radiation spectrum. However, in published documents, too close contact with broadcast sources can be dangerous.

" It's never safe to leave your cell phone too close to your body ," - said Dr. Devra Davis from the Department of Environmental Health.

In fact, mobile phone manufacturers do not deny this. Like Apple, the words "RF exposure" are written on the user guide (meaning that the phone will be exposed to radio waves).

"Many people do not notice that the warning to stay away from the phone is also printed right on their phones." - Dr. Davis said.

The harmful effects of radio waves follow the guidelines of the state of California

In text, radio waves can easily penetrate children's brains, causing many injuries and permanently affecting the development of the young brain.

Although studies of the effects of phone waves on children are still relatively small, they are enough to make people more cautious. This is not to mention studies that show that phones make it difficult for children to concentrate, cause sleeplessness, and even create some psychological illness.

In early December, the French government officially banned cell phones in primary and secondary schools. Although the purpose of the ban is to allow students to concentrate more, it is also strongly supported by a group of phone radiation experts.

" We tested the use of students' phones. The results showed that the amount of exposed radio waves exceeded French safety standards by four times. And if applied to US standards, the difference 7 times longer, "said Dr. Davis.

Besides, Davis said there has been a lot of research showing that radio waves make male sperm lose quality. " Studies show that the longer men store their phones in their pockets, the lower the sperm count, and most have been hurt."

According to Davis, the advice given to everyone when sleeping should stay away from the phone. Do not leave it under the pillow, but a few meters away. When leaving the street, please put your phone in your bag, instead of in your pocket like before.

In general, the harms of mobile phone waves will still be very controversial in the future. But at this point, we should be more careful, right?
