Computer Basics

 How to sit in front of the Computer:

1.Sit up straight with the back against the chair's       rest. 

2.The height of the chair should be enough to let       our feet touch the floor while sitting. Else use        a footrest. 

3.Sit on a chair with an arm rest, so that the       shoulders are not strained. The arm rest should    be at a height at which the shoulders are         relaxed and the elbow slightly away from the     body. 

4.Sit close to the keyboard. Place the keyboard     centered to the body. 

5.The wrist rest can be used to rest our palms while we are not typing. 

6.Mouse should be placed in the mouse tray right  next to the keyboard. 

7.Monitor should be placed on the table such that it lies at the center of the head. The top of the monitor should be 2 --3 inch above our eye level. 

8.Tilt the Monitor slightly upward as protection from screen rays that affect the eyes. 

9.The monitor should be atleast at an arm's distance from us. 

Exercises  we must do while sitting in front of the Computer:

1.Looking straight, move the neck slowly towards left shoulder. Bring it back to normal position and then slowly move it to the right shoulder. Repeat it 2--3 times. 

2.Move the wrist up and down slowly. Repeat it  2--3 times. 

 

3.Stretch the hands up, count slowly till five and then move them down to normal position. Repeat it 2--3 times. 

  

4.Blink the eyes 10 times every five minutes. This is very important to keep our eyes moist and prevent strain. 

5.Getup from the seat and take a five minutes  walk. 

            To keep our body fit while using the computer we must take a break after every one hour. Other wise it can cause body pain and lead to serious health problems.
