SMK KETARI, 27600 BENTONG PENYELIDIKAN PELAJAR PRA-UNIVERSITI 2010 RESEARCH TITTLE: BAD SIDE EFFECTS OF USING COMPUTER TO HUMAN HEALTH AND WAY TO OVERCOME STUDENT NAME: CHEN KAH FEI CLASS: PRA-U KA1 MENTOR NAME: PN. CHANDRIKA ANNE ABSTRACT This research is a study about the bad side effects of using computer to human health. Since, computer is widely used by all level of community, so we should know the bad side effect of using computers to our health. In order to reduce the bad side effects of using computers, this research suggests the ways to maintain our health when using computer. INTRODUCTION

The health problems that arise because of the use of computers, in this country had increased from time to time. There are few types of health problems that are caused by using computers, which not only include people who work in white collar jobs, but also it includes teenagers and children. Although computer have a lot of benefits to our life, but it also creates a lot of health problems. Health problems due to the use of computers used According the internet websites, www. shvoong. com and answers. yahoo. com it is found that, the use of computers can give rise to the following health problems: . Posture and Tension Sitting or slouching in front of a computer for long periods of time and making repetitive small movements with our fingers and wrists will affect our structure. Some of the effects will be direct, as in placing unusual strains on our spines and the ligaments in our wrists. More importantly, long periods of immobility will introduce habits of muscular tension, which may affect us throughout our lives. 2. Breathing and Blood Circulation When holding ourselves still for long periods of time and doing low energy work, we tend to breathe in a very shallow manner.

Long periods of shallow breathing means that a lot of stale air remains in our lungs and the efficiency of oxygen uptake from our lungs into our blood is reduced. Our blood oxygen levels drift lower and lower and the blood supply to our muscles, our digestive system, internal organs and to our brain is affected. Our bodies and our brains are unable to work at optimum levels. This can affect everything from the number of headaches we experience to our mental efficiency, our resistance to common illnesses, our physical fitness and our hearts. 3. Digestive System and Skin Health

Even if we eat the best, freshest and most wholesome food, healthy digestion depends on our stomach and abdomen being relaxed and mobile. Waves of movement travel along the tube, which makes up our gastro-intestinal tract. These waves must be able to travel freely without being affected by tension or our abdomens being compressed by hunching over ourselves. Smooth muscle movement, light exercise and even breathing, drive our lymphatic system, which is primarily responsible for waste removal from tissues and cells throughout the body. If our digestion is sluggish we feel just the same and whatever we put in our mouth is not digested properly.

If our lymph is sluggish, our skin health is poor, our breath and body odour may stink and our pimples will be worse. 4. Electromagnetic Radiation Be aware that sitting in front of a cathode ray tube which is beaming electrons directly at your face and brain is not a good idea. Those of you who get headaches from sitting in front of your screens, on your mobile phones or under fluorescent tubes beware, your bodies are trying to tell you something is wrong. 5. Eye Health Computers do not harm your eyes, but often cause temporary problems. The reason is that when you look in the distance, your eyes are relatively relaxed.

But when doing near work, such as reading your computer screen, muscles in your eyes have to work harder to keep a clean near focus. These muscles get tired after extended use, resulting in eyestrain, blurry near vision or difficulty changing focus. Dry eyes also can occur because we tend to blink less as we concentrate on our computer screen. (refer to appendix 1) Ways to maintain our health when using computers According the internet website, www. shvoong. com and answers. yahoo. com it is found that, the ways to maintain our health when using computers: 1. Posture and Tension

We should spend 10 or 15 minutes of every hour doing contrasting activities, which involve bending, stretching, moving about and generally all those things which we are not doing in front of the screen. 2. Breathing and Blood Circulation Practice taking a few deep breaths, often while working at your computer. Get up and move about regularly, try to introduce some aerobic exercise into these breaks. Do whatever it takes to get the blood moving around in the body, to get your lungs opened up and cleared out. 3. Digestive System and Skin Health Eat away from the computer.

Take a break, walk to the shop and buy some fresh food, prepare it yourself, eat it in a relaxed manner. Focus your attention on the food and the enjoyment of it. Drink regularly. Keep a large jug or bottle of fresh water on the desk. Get up frequently and make a herb tea drink like Chamomile or Rosehips or Mint for example. 4. Electromagnetic Radiation To avoid electromagnetic radiation, take regular breaks from your computer and don''t take these breaks in front of the T. V. 5. Eye Health Look into the distance every 15 minutes to relax your eye muscles make a conscious effort to blink several times during the break period.

Use eye drops if your eyes become dry. You also can reduce eyestrain from your computer by moving the screen away from direct lighting, tilt the monitor screen or use a glare screen. If you wear eyeglasses, antireflective coating may be added to your lenses to reduce the effects of glare from the screen. CONCLUSION Through this research, we can obtain that the impact of using computers to our health which otherwise will be harmful to our health. If we didn’t maintain our health with a smart way, our health will be a menace by using the computer.

Therefore, every person is responsible to maintain their own good health when one uses computer to have a comfortable lifestyle. This is important to maintain a healthy life.

Yeap Tok Kheng, (2005). Reference Text Series PMR Science. Shah Alam, KHL Printing Co. Sdn. Bhd. APPENDIX Appendix 1 KUALA LUMPUR: Half of ethnic Chinese schoolchildren in Malaysia are short-sighted, according to experts who say computer games, early reading and myopic parents could be to blame. In multicultural Malaysia, some 50 percent of Chinese pupils are short-sighted compared to just 15 percent of ethnic Malays and 17 percent of Indian students, National University of Malaysia head of optometry Norhani Mohidin said, according to the Bernama news agency Monday.

Norhani said it was unclear exactly why, but researchers at an international optometry conference here said it was likely a combination of genetics and lifestyle factors. Neighbouring Singapore, which is mainly ethnic Chinese, has recorded the world's worst eyesight, with over a third of young children myopic. "Let's say that ethnicity could be one of the factors of myopia, but this is still being researched," Nathan Efron, an optometry professor from Australia's Queensland University of Technology, told Bernama at the meeting. If parents wore glasses, then there is a chance that the children will have myopia too," he said. Children in urban areas, who spend more time watching television or playing computer games, are more likely to become myopic at an early age compared to those from rural areas, he said. "In the urban area these days, children were taught to read from as young as two years old and that could also lead to myopia because they have the book close to their eyes and try to focus on how to read.
