The Proper Approaches to Become a Healthy Frequent User of Computer
If the office workers are staring at a computer every day do not pay attention to the self-protection of the eyes, not only make the eyes fatigue, but also the serious case will affect the whole body, resulting in the "computer fatigue syndrome". In addition to improve the quality of the computer screen and using a variety of self-protection methods, the placement of computer, adjustable chairs and tables as well as the sitting position are to be cared.
The ideal distance to operate a computer should be kept at 50 centimetres - 60 centimetres, with the exception of 70 centimetres, if the screen size is bigger than average. If the distance is too near, it would easily to get hurt by the radiation, and will cause myopia or deep the degree of myopia. If the distance is too far, you need to stretch the arms to reach the mouse. The sour and pain on shoulders will be caused in long time. We'd better place the computer, from the top of the screen, below the horizontal line of sight to 30 degrees with the screen tilted upward 10 degrees. On the one hand this can reduce the exposed area of the cornea, reduce dry eye syndrome; on the other hand, it can ease tension of the neck muscles and reduce the incidence of cervical spondylosis.
Seat height should preferably be a natural bent knee to 90 degrees or slightly forward, the feet are flat on the ground. The table & chair is over high and you overhang the shank. It causes oppress the blood circulation. The table&chair is over low and you coil shank. It causes oppress the abdominal organ and affects the gastrointestinal function. The backrest should lean forward so that the spine is straight, otherwise the long-term hunched waist not only oppresses internal organs, but also makes people prematurely have hump.
We had better seat in the face of the screen, do not oblique side next to the computer, or else a long time will make two adjustments of the eyes imbalance. It will also cause the neck, waist, shoulder and wrist fatigue because of over bending. Attention should also be paid to the well-ventilated, reasonable light and moderate humidity of the surrounding environment. The back of the computer should retain a certain space, so that there is room for expansion while looking at the computer.
You should pay attention to the 4 hazards of radiation as follows.
* 1. The computer radiate pollution may affect the our circulatory system, immunization,reproduction and metabolism functions. It seriously causes the cancer and accelerate cancer cells's reproduction in the body.
* The way it impairs reproductive system is mainly to decrease the quality of male sperm, induce natural abortion and foetal malformations on pregnant female.
* Third, the main expression of affecting people's cardiovascular system is heart palpitations, insomnia, menstrual disorders of some women, bradyrhythmia, volume reduction of cardiac blood, sinus irregularity, leukocytopenia, decreased immune function and so on.
* 4. The harmful effect to the human vision system is because the eye is a sensitive organ to the radiation of electromagnetism, the over-high pollution produced by electromagnetism radiation could also affect the vision system.
The Dangerous Elements in Our Daily Life That Often Was Not Paid Attention to
Heath is an important subject whch modern people pay most attention to, while talking about health, the threats of sickness, bacteria and radiation can never be avoided. However, we often overlook some details seemed simple and harmless.

Many people take refrigerator as the safty case, and think it's OK to put everything like fruits and vegetables and other food in it. But, the adaptive ability of bacteria is very strong whether in extreme oxygen-deficient environment, boiling water or oil.

Some people like to can orange juice, Durable Medical Equipment beer and other acid liquid with thermos bottles. However, when removing these liquids to the thermos bottle, it will be easy for them to produce chemical reaction with depositing fur, and the heavy metal elements of fur will dissolve into water and other liquids again.
In that way, if people drink those heavy metal elements in a long term, it will be easy to cause functional disorders of digestive system, nervous system, respiratory system and hemopoietic system of human body, and it may even lead to pathological changes. Therefore people shouldn't look down upon scale, it should be cleared periodically in order to avoid constant harm to health.
Key is the necessary thing that must be used everyday. Lots people put keys in the pocket, and some others play them as a kind of toy. People may not know that our pockets is really a "dirty bag".
