The rules of properproper proper computer use

These days we spend a lot of time in front of the computer. Therefore, we must not forget to provide the right conditions for work or play, at which we use a computer.

Remember the basic rules:

• chair and desk should be adjusted to user's height;

• the keyboard and screen of the monitor should be set at an appropriate distance adapted to the user's height and sight;

• the workplaceworkplaceworkplace should be adequately lit up;

• remember to take breaks when using the computer.

When we provide the right conditions for working with a computer, we should also use them properly.

Remember to keep your body in the right position during work. This means:

• the back should be straight and adhere to the back of the chair;

• forearms, bent at an angle close to the right angle, should rest on the edge of the desk;

• hands should be properly placed on the keyboard;

• the eyes of a computer user should be directed straight ahead, and the distance from the monitor to the face is 40 to 80 cm (depending on the size of the monitor);

• the monitor should be slightly tilted backwards.

Breaks at work

When working with a computer, we must not forget about taking breaks. The breaks allow rest to the eyes, neck, shoulder, hands, and legs muscles which remain still most of the time. The easiest way is to adopt the rule: 45 minutes of work with a computer, 15 minutes to refresh the body and mind.

During the break it is worth doing a few physical exercises, ventilate the room.
