  Computer Addiction andChild Neglect One of the most notorious examples of a computer addiction surfaced in Nevada in 2007. Michael and Iana Straw had two young children who were neglected to the point of malnourishment and serious health problems because the couple was so obsessed with playing online games (Dungeons & Dragons). They were each charged with multiple counts of child abuse [source: Fox News]. A similar case occurred in South Korea in 2005, when two parents left a 4-month-old infant alone in a bedroom to play computer games (World of Warcraft.) at an Internet café. When they returned five hours later, the baby was lying on her stomach and had died of suffocation. [source: Eurogamer].

  COMPUTER RADIATION HAZARDS Whenyou sit in front of a computer screen, you are being hit by many different types of electromagnetic radiations (EMR). Computers emit both VLF (Very Low Frequency) electromagnetic radiation and ELF (Extremely Low Frequency) electromagnetic radiation, as well as soft x-rays. As with all EMF Pollution, the closer in proximity to the source, as well as the longer the duration of time in the EMF Field, the more detrimental the electromagnetic frequencies upon the body.

  •Make specific timelimits. Set an alarm to go off in one hour and end computer time when it rings. •Set aside "computer-free" parts of the day. If your computer use starts after dinner and extends into the night, get all your computer work done in the morning and don't touch it after dinner. •Install software to restrict your access to Web sites that you visit compulsively. Find a friend you can trust to keep the passwords for the software so you can't circumvent it. Wellnomics® Risk Management is scientifically validated office ergonomics software.

It might be difficult to stop on your own. •Put the computer in high-traffic area of the house. With others looking over your shoulder all the time, you'll be less likely to overuse the computer. This is especially effective for parents who fear excessive computer use in their children. •Radiation from the computer screen can be blocked by special screen monitor shields.
