I am frequent computer user. Of course it’s interesting to know how danger for my health computer can be. Working with computer for whole day is not rare nowadays. If it’s an aspect of our work or if we use computers just for fun, there are certain risks involved with prolonged computer use. 1. Eye Disease It’s the first what occur to us, when we talk about computer harm (right?). 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. We can find many information about eyes health, as Snuz made. And it’s very important not to forget about our eyes while working on computer. 2. 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 blogging, 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). 3. Hurting Hands 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. 4. Computer Stress Injuries 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. What do you think?

10 Ways To Stay Safe Online 1. Be a responsible cyber citizen. If you use the Internet, you're a citizen of a global community-a cyber citizen. Just like being a citizen of your local community, being a cyber citizen has responsibilities. Use the Internet to share knowledge that makes people's lives better. Keep safe, use good manners and respect the laws. 2. Use anti-virus software. A computer virus is a program that can invade your computer and damage or destroy information. Anti-virus software is designed to protect you and your computer against known viruses. But with new viruses emerging daily, anti-virus programs need to be updated regularly. Check with the web site of your anti-virus software company to see some sample descriptions of viruses and to get regular updates for your software. Stop viruses in their tracks! 3. Do not open email from unknown sources. Delete email from unknown sources. Watch out for files attached to e-mails, particularly those with an "exe" extension-even if people you know sent them to you. Some files transport and distribute viruses and other programs that can permanently destroy files and damage computers and Web sites. Do not forward e-mail if you are not completely sure that any attached files are safe. 4. Use hard-to-guess passwords and keep them private. Do not write passwords down on small pieces of paper taped to your computer. You would be surprised how many people are sloppy about keeping their passwords private. Passwords that are easy to-guess are a bad choice. In other words, if your name is "Dan" do not make your password "Dan." Change your passwords regularly and don't give your passwords to anyone! Tell your family that combinations of letters, numbers and symbols are harder to crack than just words. 5. Protect computers with firewalls. Install firewalls for your family-it is not difficult. A firewall helps prevent hackers from breaking into your computer or the computers that belong to your family. Firewalls help prevent thieves from stealing and using private information including your phone number and credit card numbers, which may be stored on a family computer. 6. Do not share access to your computers with strangers. Learn about file sharing risks. Your computer operating system may allow other computers on a network, including the Internet, to access the hard-drive of your computer in order to "share files". This ability to share files can be used to infect your computer with a virus or look at the files on your computer if you do not pay close attention. Check your operating system and other program help files to learn how to disable file sharing. Do not share access to your computer with strangers! 7. Disconnect from the Internet when not in use. The Internet is a two-way road. You get information and also send information. Turning off the Internet makes sure that someone else on the Internet can't enter your computer and cause harm. Disconnecting your computer from the Internet when you are not online lessens the chance that someone will be able to access your computer. 8. Back-up your computer regularly. Help your family back up all household computers onto external media such as CD's or diskettes. 9. Regularly download security protection update "patches". Security flaws are regularly found in operating systems and application software. Companies that make software release quick fixes called "patches" that you should install to correct the latest software flaw. It is a good idea to check for security updates on the publisher's Web site for all the software you own. 10. Help your family to check computer security on a regular basis. Evaluate computer security at least twice a year. To help remember, do it when you change the clocks for daylight-savings time! Check for all of the items listed previously.

Photo Credit computer image by blaine stiger from Fotolia.com The Internet has become an integral part of many people's work and personal lives. The number of people online daily has nearly doubled over the past decade, according to research conducted by the Pew Internet and American Life Project. While internet addiction as a specific disorder was being debated for inclusion in the American Psychiatric Association's Diagnostic and Statistical Manual of Mental Disorders as of 2010, treatment centers already exist throughout the U.S. and abroad, including China, Taiwan and Korea. Physical Effects Internet overuse can lead to sedentary lifestyles, weight gain and a decline in physical fitness. Other symptoms can include carpal tunnel syndrome, dry eyes, migraine headaches, a decline in personal hygiene and back aches, according to Maressa Hecht, founder of Computer Addiction Services and a member of the Harvard Medical School. if(typeof disable_adsense_2 === "undefined") { ad_order_2 = (typeof ad_order_2 === "undefined") ?

Researchers found that study participants who exhibited signs of Internet overuse engaged disproportionately than the normal population in sites devoted to pornography, gaming, social networking and chat rooms. They theorized that Internet addicts' use of these sites as replacements for real-life socializing was resulting in depression. However, there is debate as to whether depression results from, or is a cause, or internet overuse. A study published in the "Archives of Pediatrics and Adolescent Medicine" found depression, as well as ADHD and social phobia, to increase the chances of excessive Internet use in adolescents. Sleep Disturbances Evidence also suggests that internet overuse can contribute to sleep disturbances. Studies of Chinese and American children, published in the "Journal of Sleep" and the "Journal of the American Academy of Pediatrics," found that computer use among adolescents was associated with later bed times, later waking times, less restful sleep and an overall decrease in sleep. The use of computers before bedtime has also raised concerns among sleep experts, including Phyllis Zee, a neuroscience professor at Northwestern University, that the light from screens is affecting circadian rhythms and possibly contributing to insomnia.

Effects of Moderate Use A moderate amount of computer use and game playing doesn't seem to affect social development. The social behavior of moderate computer users and nonusers was roughly the same in terms of sociability and relationships with friends and family. However, heavy computer users tended to believe they had less control over their lives than their classmates, a possible indication of inadequate socialization. Increased Hostility and Aggression After the massacre at Columbine High School in 1999, researchers and educators paid more attention to violent video games such as Doom, the daily game of choice for one of the two teenage killers. Many studies show that violent TV shows increase aggression and hostility in both children and adults. It appears the same is true of computer games. The key variable appears to be a preference for violent games, rather than the amount of time a child plays such games. Even playing Mortal Kombat for a short time increases a child's hostility and aggression. Violent computer games also desensitize children, who show less empathy and willingness to help others, according to research cited in "The Future of Children." Brain Drain In a small study of 18 Chinese university students, published in the "PLos ONE" journal and reported on Mail Online, kids who played games on their computers at least eight hours a day, six days per week showed alarming amounts of atrophy in parts of their brain, as measured by MRI scans. The scans also found abnormalities in the white matter of the brain, which coordinate communication between different areas of the mind. On Mail Online, Dr. Aric Sigman of the Royal Society of Medicine called the July 2011 report a "wake-up call." Experts fear that in addition to cognitive damage, heavy Internet use might reduce the inhibitions and decision-making ability of children, leading to damaged relationships with family members, peers and authority figures.

Google Promotes Online Safety With 'Good to Know' Campaign

Gillan Guy, the CAB's chief executive, said that “Information is a powerful tool for preventing problems from arising in the first and safety, personal data and identity theft are among the top concerns of people of using internet”.

Computer Addiction – obsessive playing of off-line computer games, such as Solitaire or Minesweeper, or obsessive computer programming.

The Internet provides a constant, ever-changing source of information and entertainment, and can be accessed from most smart phones as well as tablets, laptops, and computers. Email, blogs, social networks, and message boards allow for both public and anonymous communication about any topic. But how much is too much Internet usage? Each person’s Internet use is different. You might need to use the Internet extensively for your work, for example, or you might rely heavily on social networking sites to keep in touch with faraway family and friends. Spending a lot of time online only becomes a problem when it absorbs too much of your time, causing you to neglect your relationships, your work, school, or other important things in your life. If you keep repeating compulsive Internet behavior despite the negative consequences in your offline life, then it’s time to strike a new balance.

Talk with your child about his/her excessive computer usage

Move the computer to an open area if it’s not already in one – sometimes taking it out of the child’s bedroom is sufficient to reduce their computer usage, and it makes it easier to monitor their usage.
