Several studies have been conducted to try to provide answers. You’ve probably heard that it was inadvisable to stay close to a microwave oven on. Indeed, for cooking, microwave ovens emit a frequency of 2450 MHz. This has the effect of exciting the water molecules. The friction between these molecules, so they release heat, which allows cooking. In an oven with no anomaly, the waves are like in a Faraday cage. But the wavelength of our cell phones is similar to that of microwave ovens. We can therefore legitimately wonder about the effects they can cause our body: The human body contains 60% water!
The heating effect, found in a person who uses his mobile for 20 minutes, is an increase of 1 ° C tissue temperature of the head in contact with the laptop. This increase can be felt up to 10 cm inward from the head, the consequences are a temperature difference of both sides of the brain. but the effects involved in this thermal imbalance are not yet known …
It will also say that mobile phones could cause headaches, when is it? Some people complain of headaches after prolonged use of mobile. A study on rats suggests the hypothesis that radiation from a phone could alter the permeability of the vessels of the brain. This, in humans suffering from chronic migraine, would increase in frequency or intensity of pain.
Another effect, exposure to radio frequencies emitted by mobile phones. They could be dangerous for users of metal-rimmed glasses or wearing earrings. Again nothing has been proven scientifically. Some studies seek to prove that there is no risk of cancer linked to mobile. In contrast, a much more recent UK study shows that people who regularly use their phones for ten years would have 40% additional risk of developing tumors of the nervous system.
If the device is a transmitter it is also a wave receiver. He received via antennas placed on the roofs of buildings or water towers. This can cause malfunctions of electronic equipment. Cases of medical equipment have been collected disturbed.
We see that this question does not cut answer. If you have concerns, use your cell phone with a handsfree kit. You can always follow these tips without falling into the mobile phone phobia.
