Describe some ways in which computers may affect your health?

Answer 1

Computer Monitors are well known to emit electromagnetic fields. They emit low-frequency magnetic fields of around 60-Hz. They are believed to present a greater exposure risk than a televsison because users sit much closer to their screens. Also, the commonly held belief that LCD computer monitors emit less EMF radiation than other types of monitors, is not completely true. LCD monitors require less power to run, but LCDs can emit high levels of electric fields. Backlit LCD displays can emit high levels of electric and magnetic fields. Although its questionable that the amount of magnetic and electric fields emitted by a computer monitor could pose a health risk. There is solid proof that exposure to higher levels of these fields, such as living near power lines, can cause major health risks.

Higher level EMF exposure can cause many types of cancer such as, leukemia, breast cancer and brain cancer. There is even some evidence that it may cause miscarriages and even suicides. One mechanism that electromagnetic fields could damage our health is by generating excess amount of ozone in the air we breath. Ozone generates free-radicals and is very caustic. It is good at keeping radiation out of our atmosphere, but it is very toxic when we breathe it into our bodies.

Answer 2

Computer technology affects people's lives because they spend a lot of time with computing devices and resources, such as mobile phones and the internet. People depend on computers in doing almost everything, including purchasing goods, making bookings, inquiring about family and friends, and making decisions. In addition, computer technology allows people to overcome barriers, such as distance, in education and work activities. According to HowStuffWorks, computer technology blurs the line between private and professional lives. Computer technology allows storage of a lot of information and simultaneous retrieval of data. It also eases the manipulation of data, such as photos and sound. However, The Telegraph argues that people are less likely to remember what they see or read on computers. In addition, computer technology can be distracting, and it may create distance among family members. Computers stream several pieces of information, causing people to skim or scan through them, instead of thorough and reflective reading. According to The Telegraph, the media images that children view through computer technology, such as violence on online media, has negative effects on their social and psychological processes.
