Everything is good in moderation

The famous medieval alchemist and physician Paracelsus once said, in principle, a paradoxical thing - everything around us is poison, and only the dose distinguishes poison from the medicine. The same idea can be found in folk proverbs, starting from the ancient Latin epistle - omnne nimium nocet, which in translation means - everything is good in moderation. And this can be attributed to the world around us. For example, ultraviolet radiation from the Sun gives a wonderful tan, increases the vitamin D content, which helps a person to fight various ailments, rickets. The light of our luminary also gives joy and helps against depressions. But too much light radiation dose leads, at best, to heat stroke, burns and even skin cancer. But does such a rule in the world, thoroughly impregnated with computer technology and various gadgets?

Omne nimium nocet - everything is good in moderation

The rapid growth of computer technology has led to the emergence of various diseases and syndromes, unknown before. Let's start from the "computer visual syndrome".

While working at the computer, the eyes become very tense. Images of letters, numbers, figures on the screen consist not of solid lines, as on paper, but of individual points that do not have clear boundaries. Therefore, signs and lines are less contrasting than they are in the book. This is especially true for monitors and tablets of poor quality. The user deteriorates eyesight, there are headaches, fatigue, the image splits. The eyes of a person are constantly refocused between objects that are at different distances and under different illuminations. The monitor screen is flat, and we are used to working in a three-dimensional world. Therefore, the view becomes inactive, the field of view narrows. The lack of eye movement worsens the nutrition of his tissues. In addition, a decrease in the number of blinkers leads to the drying of the thin layer of the tear, a decrease in tear, which causes the eyes to become inflamed and redden. Another thing - the eyes are looking directly at the light source. Photoreceptors work without interruption, light-sensitive pigments do not have time to recover. And still you need to consider that the monitor is surrounded by an electromagnetic field...

Especially these problems concern children whose eyes have not yet fully formed. Doctors recommend limiting the duration of work and games on the computer. So, children 3-4 years should not sit in front of the screen for more than 20 minutes, and from 6-7 years can increase the playing time to 30 minutes a day.

But lately, you can hear the phrase "text neck" more and more often. What is this thing? The human head weighs several kilograms. But when we tilt it, the load on the cervical spine begins to increase. At an angle of 15 degrees, our neck "feels" an increase in the "severity of the head" twice, at an angle of 30 degrees - more than three times, and more than 45 degrees - 5-6 times! This is the load that comes as a bonus to our gadgets - smartphones, tablets and laptops.

A study conducted in this direction and published in the US is already fully replicated by various Internet sites. In it, these loads were given a new definition of "text neck" (text neck) and argued that such a situation could lead to early wear and erasure of the spine, degeneration and even surgical operations. Some doctors consider this syndrome a new epidemic, because most users of new gadgets go and sit with their head down.

According to statistics, each smartphone user spends an average of 2 to 4 hours a day, sitting hunched. He plays games, dials and sends messages, sits in various social networks, reads e-mail or watches video. In a year this results in a period of time from 700 to 1400 hours, and high school students and students can sit in this hunched position up to 5000 hours!

Doctors believe that the lowered head leads to constant overload of the neck muscles, which leads to their deformation, pinched nerves, even herniated intervertebral discs. It can also cause pain in the neck, head and spine, and in the long term even reduce lung volume by almost 30% and lead to heart disease.

What to do? And you need to move more, keep your head straight when working with a laptop or smartphone. With hard work, regularly take breaks, which do not sit, but bend over, stretch, crouch to increase blood flow and prevent stagnant phenomena.

The most important thing is to understand that everything is good in moderation. The real life is more beautiful than any computer game, and a computer or gadget is just a machine, the skillful use of which will make our life more interesting.
