It is difficult to imagine the modern world without computer technology, which greatly facilitates human life and work. But if you spend a lot of time at a personal computer, the body is seriously damaged.
Sitting position
Often, a person at a personal computer takes a relaxed posture. At the same time, due to the static nature, it is unpleasant and forced: the muscles of the back, arms, head and neck are tense. The result can be scoliosis in children, osteochondrosis in adults.
With a long stay at the computer between the body and the seat of the chair, a certain effect of heat compress develops. This often leads to stagnation of blood in the pelvic organs. Often, the consequence of this phenomenon is prostatitis and hemorrhoids, that is, diseases that require unpleasant and long-term treatment. In addition, such a sedentary lifestyle leads to obesity.
Electromagnetic radiation
The question of the negative impact of electromagnetic radiation on a person is rather complicated. Hundreds of scientific articles are devoted to its study. Modern LCD monitors have certainly become much safer than the original monitors a decade ago. Despite this, unpredictable low frequency effects from transformers, electric motors, etc. remain. Scientists at the moment do not undertake to predict their impact on the health of the human body and the consequences in the future. At the same time, they warn that such an effect leads to some changes in the state of the body, in which it is more vulnerable to viruses, xenobiotics, etc.
Overloading the joints of the hands
As a result of systematic or regular striking of the keys, a feeling of weakness arises in the fingers. This condition can lead to damage to the ligamentous and articular apparatus of the hand. Over time, this can become chronic.
It should be noted that repetitive long-term work with fingers and hands can lead to carpal tunnel syndrome. To avoid this ailment, you should follow simple recommendations for the work schedule and organization of your workplace. For example, take a short break every hour, doing a special set of exercises for the hands.
Increased stress on vision
The human visual system is by nature not adapted to look at and examine images on the monitor screen. The eyes react even to the smallest vibration of a picture or text and to the flickering of the screen. This overload leads to a loss of visual acuity over time. It is worth noting that poor choice of fonts, colors, inconvenient positioning of the monitor screen and incorrect layout of windows in the programs used and used also have a bad effect on vision.
To avoid vision problems when working at a computer, you must follow the basic rules. The workplace should be well lit. The sun's rays should never get directly into the eyes.
People who have vision problems need to regularly consume foods that strengthen the vessels of the retina of the eyes: carrots, currants, blueberries, cod liver, etc.
Special eye exercises provide excellent assistance. It takes no more than five minutes and consists in alternately shifting the gaze to distant and near objects, frequent blinking, etc.
