It is unlikely that any of us imagines life without the regular use of TV and computer. TV is needed for the evening entertainment shows, news programs, and sports broadcasts. A computer can be used not only for study or work but also for hidden object games. How harmful are they, and what is more dangerous – a TV or a computer?
What are the negative effects of watching TV on human health? Let's figure it out.
The harm of radiation is greatly exaggerated. Only an old or faulty cathode-beam television receiver with a kinescope can emit small X-rays, and its negative effect on a person has not been proven.
Modern televisions, even if they have radiation, are only electromagnetic or thermal, but the doses are so small that they are absolutely harmless to humans.
In a special risk group are children whose vision is still unstable and more susceptible to negative influence. To protect your eyesight, the TV should be watched at a certain distance and time. It is also necessary to do special exercises for the eyes and visit an ophthalmologist at least once a year.
Such a lifestyle leads to a huge number of problems: the curvature of the spine, excess weight, the development of diseases of the cardiovascular and respiratory systems, decreased immunity, etc.
Lack of live communication, depressive states, problems with self-esteem, the development of aggressive behavior due to a large amount of violence on the screen, and even a banal addiction – these are the consequences.
What harm does this universal invention of the human mind bring? See further.
Even the most modern and safe monitors have a small amount of electromagnetic radiation that can affect the functioning of body systems, so time spent at the computer should be limited, especially for children.
It is no less, if not more, than when watching TV, because, in the case of a computer, the distance from a person’s eyes to the screen is reduced several times. It must be at least 30 cm between the eyes and the screen surface, while it is also important to place the monitor at a right angle to the eyes, moisturize the eyes and the room around, do visual exercises, take breaks when working with a computer, and regularly check your vision.
Here, the computer also provides harmful effects, especially on the skeletal system and the cardiovascular system.
It is necessary to highlight this aspect. It can be an addiction to computer games, when all other entertainment – outdoor recreation, travel, sports – lose their value. Such addiction is already recognized as a disease and requires serious treatment.
Both the TV and the computer can be your enemies or your friends. It is very difficult to say which is more harmful; the risk factors are about the same. As for the benefits, the computer is definitely much more profitable and multifunctional. It will easily replace the TV.
