What are the effects of playing video games

Using TV, video games and players,mobile phones, etc expose you to electromaganetic fields. In short, well you will be exposed to a lot of radiation i.e., infra red, mcrowaves, UV, etc. See information below

Common types of non-ionizing radiation include some ultraviolet (UV) rays, visible light, infrared rays, microwaves, and radiofrequency rays (radio waves), and electromagnetic fields. Electrical devices, heaters, and cell phones all emit (send out) non-ionizing radiation.
Concerns have been raised about a possible link between some types of non-ionizing radiation and cancer. The way in which it might do this isn't clear. Non-ionizing radiation doesn't damage DNA directly, but it may be able to affect cells in other ways. The possible links between some of types of non-ionizing radiation and cancer are discussed below. But at this time, non-ionizing radiation has not been established as being able to cause cancer.


Electric currents create extremely low-frequency (ELF) electromagnetic fields, which are at the low-energy end of the electromagnetic spectrum. We are all exposed to electromagnetic fields from the earth itself and from man-made sources. Examples of man-made sources include power lines, household wiring, and electrical appliances (when they are on).
The possible link between electromagnetic fields and cancer has been a subject of controversy for several decades. Because we are all exposed to different amounts of these fields at different times, the issue has been difficult to study.
One of the main concerns has been whether ELF affects the risk of childhood cancers such as leukemia and brain tumors. In the studies that have looked at a possible link with childhood leukemia, the results have been mixed. If there is an increased risk it is likely to be small, but a weak link cannot be ruled out entirely. Studies of other childhood cancers have generally not found any strong links to electromagnetic fields.
Most studies in adults have not found links between electromagnetic fields and cancer.
It's not clear exactly how electromagnetic fields, a form of low-energy, non-ionizing radiation, could increase cancer risk. Studies of lab animals have generally not found that magnetic fields increase the risk of cancer. The absence of a link in animal studies makes it less likely that human exposure to electromagnetic fields, at home or at work, affects cancer risk.
The National Institute of Environmental Health Sciences (NIEHS) describes the scientific evidence suggesting that electromagnetic field exposures pose a health risk as "weak". But because a possible increase in cancer risk can't be ruled out completely, the NIEHS has advised that people concerned about EMF exposure may want to consider practical ways to reduce their exposure, such as finding out where their major EMF sources are and limiting the time spent near them. There are more costly actions, such as burying power lines or moving out of a home, that might also lower EMF exposure. But because scientists aren't sure if EMF poses any health hazards, it's not clear if such actions are warranted, according to the NIEHS.  Television and computer screensModern television and computer screens give off several kinds of radiation, most of which is in the extremely low frequency (ELF) range. Concerns have been raised about possible health problems associated with the use of these screens, including cancer and birth defects. The amount of energy given off by these screens is far below government exposure standards, and at this time the available evidence does not support links to either of these health problems. Research in this area continues.  Cell phones and cell phone towersCell phones and cell phone towers use radiofrequency and low-level microwave radiation to transmit and receive signals. Neither cell phones nor cell towers have been conclusively linked to increased risks of cancer, but most researchers and government agencies agree that more research on cell phones is needed, especially with regard to long-term use and use among children. For more detailed information, refer to our documents, Cellular Phones and Cellular Phone Towers.  Radiofrequency radiation (radio waves)Radiofrequency radiation is emitted from radio and television broadcast transmitters, citizen band radios, and electric heaters. There is little evidence that these exposures affect cancer risk.  MicrowavesMicrowaves have energy levels in between radio waves and infrared waves. Like other forms of non-ionizing radiation, they do not have enough energy to directly damage DNA. Microwave radiation is used in microwave ovens and radar equipment. Cell phones may also use some low-energy microwaves.  Microwave ovensMicrowave ovens work by using very high levels of microwaves to heat foods. The microwaves are contained within the oven itself. When microwave ovens are used according to instructions, there is no evidence that they pose a health risk to people. Nor do microwaves make food radioactive.
Exposure to high levels of microwaves can have effects on health. Such exposure could lead to a painful burn or to the development of cataracts in the lenses of the eyes. These injuries are caused only by exposure to large amounts of microwave radiation, however, and the small amount that can leak from a microwave oven does not cause these problems.
Some older models of pacemakers might be affected if the person with the pacemaker gets too close to a microwave oven while it is on. This is unlikely to be a concern with modern pacemakers, which are shielded from outside electrical activity.
