The warnings we've heard about smart phone risks seem to be getting more and more verified, and this time the new warnings come from the United States and just from California, which warned its citizens not to keep their phones close for long periods of time.
The California Department of Public Health warned state citizens against misuse of smartphones, advising them not to keep them in their pockets for long periods of time, but anywhere near them, especially if they did not use them or were in prolonged use And warned the administration to keep smart phones close to its users during their sleep.
Not only that, the US Department of Health indicated that the risk increases if the phone is in search of the network in areas where the network signal is unstable or weak, and the US Foundation has reported a study it had prepared in 2009 Warns of the risk of signals and vibrations from these devices, which may cause serious diseases such as cancer, especially with the spread and widespread use by all groups, including children or pregnant women, for example.
