Watching TV — news, series, entertainment programs — takes a huge amount of time, but an invention that could benefit a person most often leads to degradation and health problems. Why it is harmful to watch TV for a long time is explained not only by ophthalmologists, at the moment other specialists are in solidarity with them.
The dangers of watching TV for a long time
First of all, watching TV for a long time is harmful to the eyes, ophthalmologists have long been arguing that the negative impact of the included screen on human vision:
- During the entire time of watching programs on a television screen, vision is focused at one point. Prolonged static loading can lead to deformation of the lens and loss of its ability to change rapidly.
- The constant flickering of the screen provokes a constant expansion / contraction of the pupil, an uncontrolled change in its size leads to an increased load, which negatively affects vision.
- The human organ of vision is able to distinguish even very small details, but the TV screen offers him a blurry image of these details. Failure to use all the possibilities of the eye leads to degradation of the retina.
Psychological factor and information format
Why it is harmful to watch TV shows and other “blue screen” programs for a long time, psychologists also tell. Their arguments refer to the very information that the viewer receives from programs, movies, news, entertainment programs and even advertising. It is noteworthy that the consciousness and subconsciousness of the viewer perceive the same information in completely different ways.
Let’s analyze how watching movies of various genres affects a person.
Action, crime news, thrillers
The impact on the psyche depends on the chosen format of information, for example, violent films or too negative moments in them contribute to the fact that the subconscious mind begins to perceive everything that happens as a norm — an unreal picture begins to acquire real features, to a greater extent this format affects the immature psyche teenagers.
As a result, the behavior of the viewer may change in a negative direction: the appearance of aggression, unreasonable cruelty, irascibility — such signs are becoming more common. For toddlers, tapes of this genre are frightening, cause violent tears, and can cause psychological trauma.
Melodramas and series
Long-term viewing of the so-called «soap operas» forces the viewer to make comparisons with his own life, which, after a series of arguments «for» and «against», seems to be a miserable existence, complexes develop as a result of torment and torment, apathy and depression develop.
Melodramas and soap operas can be the main reason for unfulfilled dreams and ridiculous expectations — after watching such films, girls look for princes on a white horse, boys look for beauties who even wake up with makeup on. What the TV forgets to tell in this case is everyday problems and the real side of life for which young people may not be ready.
Entertainment programs and advertising
Most entertainment programs not only do not contribute to development, but rather even slow it down. Flat humor and “below the belt” jokes lead to mass stupidity of the nation, and long-term viewing of such shows does not relax the brain, as is commonly believed, but takes away from real problems, as a result, the viewer can acquire such traits as indifference, lack of compassion, inability to to think sensibly and make serious decisions.
It is harmful to watch TV for a long time and because of the high concentration of advertising. The engine of progress can become a significant reason for the lack of money — the viewer begins to buy more and more things that he does not really need.
Long-term viewing of television programs spoils the figure and physical health. A sedentary lifestyle, wrong posture when watching TV, eating junk food during this time will sooner or later affect your health. In addition, TV replaces more useful activities and takes up a huge amount of time. Instead of watching TV shows and movies, a viewer could do jogging, swimming or yoga, improve their professional skills, learn something new, read an interesting book, go for a walk — this is several times more useful.
Why is it bad to watch TV in the dark?
Is it harmful to watch TV in the dark and why? A sharp change in the light load on the nerve of the visual organ provokes not only eye fatigue, but can also lead to such a serious disease as glaucoma. It is characterized by increased eye pressure and the development of various visual defects.
By the way, to prove the harm of watching TV in the dark, an amusing experiment was conducted: those who wanted to participate were divided into two groups, the first group watched the movie with the lights on, the second — with the lights off. At the end of the film, the participants were asked to complete several surveys, and brain scans of the head were also taken.
What the experiment revealed: watching TV in the dark is harmful primarily to vision — men and women from the second group noted the resulting eye fatigue and tension, in addition, their reaction rate was much lower.
Is it possible to watch TV for a baby, a small child
The development of the child and his formation as a person occurs from birth, and not from 5-7 years, as was previously believed. Unfortunately, not all parents understand and take note of this. For some reason, it is more convenient for adults to assume that small children, and even more so infants, do not understand anything.
But can a baby watch TV? No, even cartoons cannot be watched by a baby — loud sound, bright screen colors and a constantly changing picture can negatively affect the baby’s nervous system, which perceives this entire spectrum as irritants.
The thing is that in the first year of life, children experience too strong emotions, but they do not know how to control them, so even joyful impressions must be “dosed”, otherwise the nervous system of the baby will be exhausted. It is harmful for children to watch TV at such a young age, its negative impact affects the development of attention in a child. Self-relevant sounds and static pictures replace background noise and changing TV plots, resulting in attention-deficit/hyperactivity disorder, developmental delay (mental and physical).
Can a child watch cartoons at an older age? At 2-3 years old, the baby can already be shown a good cartoon, not forgetting the norm — 15-20 minutes a day.
Watching TV lying down
Why is it harmful to watch TV while lying down? The body takes an uncomfortable posture, in which the neck and head suffer first of all. As a result of prolonged stagnation, the load on the spine in the cervical region increases, which can contribute to the development of headaches, discomfort in the neck, and stiffness of movements.
How to minimize harm
Watching TV can be extremely harmful to health, but it is not always worth giving up watching interesting films and programs altogether, but it is necessary to reduce the negative impact:
- The visual distance to the TV screen should be at least three meters.
- There must be a light source in the room.
- No need to eat while watching TV, its volume is no longer controlled.
- While watching TV, you need to sit in a comfortable and correct position: keep your back and head straight, do not cross one leg over the other, do not take a prone position.
- The time spent watching TV should be no more than 2 hours a day.
- It is not recommended to watch TV later than two hours before bedtime.
It is also recommended to watch not all programs shown on TV, but those that have a positive or neutral effect on the psyche. Modern cinema with an abundance of a wide variety of films allows you to choose tapes for every taste.
