Starting from the 1990s, cell phones have become extremely popular in our country. Nowadays mobile phones are maybe the most frequently-used things in the whole world.
This hitting stride popularity has impelled scientists to conduct wide variety of studies, in order to clear, whether these devices could bring harm to human's health.
The main reason is about radiation. All cell phones emit radiofrequency waves and send signals to base stations.
Radiofrequency is a type of electromagnetic radiation, which is divided into ionizing and non-ionizing. Radio waves belong to non-ionizing radiation. This form of energy is used not only in cell phones communication, but also in microwaves, television and radio transference.
Growing amount of cell phones users, as well as increased number and length of the calls, make people concern about potential hazards of their mobile devices.
While ionizing radiation has ability to damage cells DNA, increasing risks of cancer, non-ionizing sources have too low power frequency to cause the same effect.
Though the International Agency for Research on Cancer has classified radiation from the cell phones as possibly carcinogenic, studies have shown contentious results.
One research has found that cell phones can slightly increase glucose metabolism in the brain. But nobody really knows, what does it mean for the human's health.
In fact, numerous investigations haven't detected any correlation between phone use and cancer development.
The only proven biological effect of radio waves is heating, which can be absorbed by the body tissues.
However evidence is conflicting, and probably more research is needed to recognize exactly, whether or not cell phones can elevate cancer risks.
According to the CDC's and the WHO's data, using mobile phone while driving increases chances of car accident 3-4 time, even if you prefer hands-free kit.
It was also found that phones can probably interfere with normal functioning of some medical devices (heart pacemakers , hearing aids and defibrillators), when being too close to them.
In addition to this, many scientists investigate a link between cell phone use and developing acoustic neuroma – benign overgrowth of the nerve, which delivers signals from the brain to ear and backwards.
Other potential health influences include reduction of male fertility, sleep disturbance and eye strain.
Healthcare professionals recommend trying speaker phone function and hands-free devices to reduce your exposure to radiofrequency. It’s also a good idea to limit the time, you talking with your friends on the phone. You’d better meet them in the cafe or walk together to speak about all news in reality.
