Does the warming affect my phone
Do cell phone rays damage the brain?
Globally, more people have a mobile phone than access to a working toilet. In addition, many users often hold their cell phones to their ears for several hours a day. How unsettling is the idea that the radiation emitted by the devices could affect the brain or even cause tumors! Such fears persist and are sometimes even fueled by scientific studies. But most of them have serious methodological shortcomings.
Cellular communications use high-frequency electromagnetic waves that travel very quickly. Unlike radioactive radiation, this non-ionizing type of radiation has too little energy to separate electrons from molecules or to damage the genetic material. What health risks are then conceivable? When making a phone call, the head absorbs some of the energy, causing the tissue to heat up by less than one degree Celsius. This is considered harmless and is comparable to the natural fluctuation in body temperature over the course of the day. Beyond this thermal effect, scientists have so far not been able to determine any effects of cell phone radiation on the body, despite intensive research.

Both the World Health Organization and the Federal Office for Radiation Protection give the all-clear: internationally established maximum values are completely sufficient to rule out any health risks. The International Cancer Research Organization serving the WHO, the IARC, classifies cell phone radiation as "possibly carcinogenic". Gliomas, in particular, the most common type of brain tumor, may be caused by radio waves, she says.
If the use of mobile phones actually promoted the development of brain tumors, these would have to occur more frequently for a number of years - but this is not the case
What is this judgment based on? The »Interphone« study carried out in various countries was decisive for the classification of mobile phone radiation. In this study, no general connection was found between mobile communications and gliomas. However, the rate of cancer cases was slightly higher among those subjects who had been using their cell phones for more than half an hour every day for a period of ten years. On the other hand, the same study also showed that people who talked on the phone between 15 and 30 minutes a day actually developed fewer gliomas than those who did not use the cell phone at all. A highly unclear finding that could very easily have come about by chance. In any case, no linear relationship between dose and supposed effect could be seen in the data. Another reason for doubt: if mobile phone use actually promoted the development of brain tumors, these should have occurred more frequently for a number of years - but this is not the case.
Researchers have also investigated the possible effects of cell phone radiation on sleep quality, the ability to concentrate and memory. Here, too, no clear effects could be determined. According to some studies, test subjects could concentrate less well in the presence of an electromagnetic field - but better in other studies!
Why are such possibly positive effects often hidden? This is probably due to a special property of the radiation itself. We cannot perceive it with our senses, and yet calls, messages and immense amounts of data arrive on our device. Because of this combination, we develop a kind of basic skepticism, for example towards genetically modified foods or nanomaterials.
