Harmful to watching TV

Visual impairment

First of all, prolonged watching TV is harmful to the eyes, oculists have long been arguing for the negative impact of the on screen on a person’s vision:

• During the whole time of watching programs on a television screen, the vision focuses at one point. Long-term static load can lead to deformation of the lens and the loss of its ability to quickly change.

Psychological factor and information format

Why is it harmful to watch TV shows and other blue screen programs for a long time, psychologists say. The arguments they cite apply to the information that the viewer receives from broadcasts, movies, news, entertainment, and even advertising. It is noteworthy that the consciousness and subconscious mind of the viewer perceive the same information in completely different ways.

Let’s look at how movies of various genres affect 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 begins take everything that happens as a norm - an unreal picture begins to take on real features, to a greater extent this format affects the immature psyche teenagers.

As a result, the behavior of the viewer can change in a negative direction: the appearance of aggression, unjustified cruelty, temper — such signs are found more and more often. Toddlers are frightened by tapes of this genre, cause violent tears and can result in psychological trauma.

Melodramas and TV shows

A long viewing of the so-called “soap operas” forces the viewer to make comparisons with his own life, which after a series of the arguments “for” and “against” seem to be a miserable existence, complexes develop as a result of torment and torment, apathy develops and depression.

Melodramas and soap operas can become the main reason for unfulfilled dreams and ridiculous expectations - after watching such films, girls are looking for princes on a white horse, boys are beauties who even wake up with make up. What the TV forgets to tell in this case is domestic 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 inhibit it. Flat humor and “below the belt” jokes lead to a massive stupor of the nation, and prolonged viewing of such shows does not relax the brain, as is commonly believed, but takes them away from real problems, as a result, the viewer can acquire such features as indifference, lack of compassion, inability to think sensibly and take serious solutions.

It is harmful to watch TV for a long time because of the high concentration of advertising. The engine of progress can be a significant reason for the lack of money - the viewer begins to buy more and more things he does not really need.

Physical health

Prolonged viewing of television shows spoils the figure and physical health. A sedentary lifestyle, improper posture while watching TV, eating junk food during this time will sooner or later affect your health. In addition, the TV replaces more useful activities and takes a huge amount of time. Instead of watching programs and films, the viewer could do running, swimming or yoga, increase his professional skills, learn something new, read an interesting book, take a walk - it's a few times more useful.

The development of the child and its formation as a person occurs from birth, and not from 5-7 years, as was previously considered. Unfortunately, not all parents understand this and take note. For some reason, it is more convenient for adults to consider that small children, and especially babies, do not understand anything.

But can a baby watch TV? No, even cartoons cannot be watched for an infant - loud sound, bright colors of the screen and constantly changing the picture can adversely affect the baby’s nervous system, which perceives this entire spectrum as irritants.
