The Problems of Using a Computer Too Much
The effects of computer usage have been long debated but it is true that excessive computer usage contributes to various long-term and short-term health problems.
Repetitive Strain Injury
Repetitive strain injury occurs when areas of the body have repetitive movements over a long period of time. Typing, mouse usage and even poor posture can cause repetitive strain injury. Symptoms can range from mild pain to severe pain.
Eye Strain
Eye strain happens when you strain your eyes by using them continuously, causing pain and headaches. This can happen because of reading, studying and computer usage, especially if you don't take enough breaks while using your computer for several hours. Usually eye strain will go away once you rest your eyes.
Back/Shoulder Pain
Poor posture and continual computer usage can result in back and shoulder pain, according to a study of 30,000 teenagers from the University of Bergen, Norway. Overusing computer can become a big problem because it results in continuous pain.Correcting your posture and taking plenty of breaks can alleviate some of the symptoms.
Depression
Sitting in front of a computer for five hours a day can increase the risk of depression. Mental disorders and sleep disorders requires the restriction of computer use to less than five hours a day. Restricting computer usage may actually be good for your mental health and symtoms of depression may be decreased if you use the computer to chat with friends and family in a short time.
