BLACK AND WHITE OF USING COMPUTER

Nowdays, most of people are using computer in their activity.Many of people argued that they can't work without using computer.As the fact computer give us many advantages forexample when we write in computer we can save  our time and edit it again whenever we want doesn't like typewriting.Computer can be our friends but on the other hand,computer also can be our enemy when they give us bad effect especially for our health. There are some disease that caused by using computer below.

• EYES

 Prolonged computer use could be linked to glaucoma, especially among those who are short-sighted. Our eyes are very badly affected by how long you stare at that bright screen. We stop blinking and start staring which makes our eyes strain and dry out. Make sure you look away from the screen and close them for a few seconds every few minutes.

• BAD POSTURE

Bad posture is enemy number one. Check your posture now! You should be able to reach the keyboard and mouse whilst bending your elbows at 90 degrees, with your shoulders relaxed. If you are stretching, this could cause problems. Your back should be straight and the top of the monitor should be just below eye level. If your monitor is to the left or right of your keyboard you are putting strain on your neck.
Long periods of time at the computer while working or reading often leads to pain in the lumbar region of the back. Neck and shoulder problems also result from poor seating and the poor organization of equipment on the desk (stretching for the telephone or files etc).

• HAND AND WRIST LACK

Your hand and wrist ache after working at the computer all day, and they sometimes start feeling numb. Research in recent years has found that things like typing and sewing rarely cause carpal tunnel. Wear splints while you work to keep your wrists from bending too high or low, and use a keyboard tray or adjust your chair so the keyboard and mouse are below your elbows and your wrists are level. It is really important to give your fingers, wrists and hands
a break from resting on the keyboard all day. A
tennis ball is a great way to do this. Every time you need to think you should grab the ball and give it a few quick squeezes. This will do wonders for your joints and muscles.

• STREES

Many people suffer from structural problems related to the physical stress of sitting incorrectly, or for too long in front of their computers. So there are chances you've experienced a fair amount of computer stress, from minor frustrations here and there to a virtual visit to computer hell.

High levels of stress can kill you, don't make mistakes! Highly stressful workers have a higher risk of developing heart diseases and even cancer. So make sure that you can manage your stress. Start making something to reduce it, don't wait till computer stress will be the main problem in your life. Taking frequent breaks is an important step in preventing repetitive computer stress injuries.

Thus, it shows up that there are several problems that occur with prolonged computer use. It is also clear, however, that if certain rules of using computer are observed the risk of any of these problems can be minimized and computer users affected with computer related disorders can avoid or treat them. I consider that persons should have active lifestyle and an ergonomic computer work station, thereby even hardly computer working can't affect their health.
