           COMPUTER AND HEALTH


  Until recently, people assumed that
the basic mechanism of electromagnetic fields on living 
organism is "Thermal" tissue damage. What does this mean? The 
magnetic field creates a high frequency in the body so called. 
eddy currents, or currents Foucault, which cause heating of the 
body. This principle is widely applied in industry, for 
example, to melt the solder. Proceeding from this theory and 
developed safety standards. Recently, however, there is 
increasing evidence that there are other ways interaction 
between electromagnetic fields and living organism. Among these 
proofs appear and cancer, and hormonal diseases, and much more. 


  First of all, it was found the effect
Sun on the human condition. More precisely, not
Sun itself, and periods of change in its
activity. At this time, the magnetic field
Earth is undergoing some changes,
thus creating magnetic storms.
People soon get tired, they are harder to concentrate, many 
exacerbated by chronic diseases, especially heart. Only that's 
not always people who see their state of health to solar 
activity. 


  Oscillation frequency of the electromagnetic waves
Earth - about ten hertz, and the human brain
adapted exactly to this frequency.
Imagine: you're standing on the deck of the ship
while pitching, and particularly unpleasant sensations you do 
not know. But here began the storm: vibration waves have 
dramatically changed the frequency and amplitude. You after a 
while not so good will. They say that you - seasickness. Same 
thing here: a little Only the sun erupted in earnest, so

once your brain is left in the dead of protection. " Man loses 
all ability for analytical thinking, depressed, no longer 
orient themselves in space and etc.



  In principle, this phenomenon is natural, and
Nowhere on it does not go. Then acts
so to speak, "the law of black and white stripes."
But in life, as always, everything is
somewhat more complicated ... Grave consequences
for a person related to scientific and technical
progress, especially in the field of electronics and 
information. 


  The impetus for research in these
areas was the rapid spread
radiotelephones. Even a layman knows
what happens to the steak, placed in
microwave. What affects the same
very light, only a lower intensity, the brain radiotelephone 
user, who is away at a distance of only one or two inches? 


  The first sounded the alarm Americans, when
manufacturers of cordless phones offered
number of claims of relatives of people who died from
brain cancer, during the lifetime of active use of wireless 
phones. Studies have shown a reduction in the functioning of 
the thyroid gland. And from this reduced oxygen consumption, 
slows the rate of metabolic processes. Symptoms - loss

hair, dry swollen skin with an earthy
shade (eg "bags under the eyes)
hoarse voice, etc.


  In Russia there is a rule limiting
power electromagnetic radiation.
It is "only" ten microwatts.
"Total" in quotes - because the vast majority of cell phones is
10-100 times greater than the maximum permissible
values. The study observed the microscopic parts of the brain
which is literally cooked.
Therefore, it is possible that a similar phenomenon
can lead to cancer of the brain.


  Okay, we'll have no radios. But we have computers with 
monitors or television. Studies have shown

The most dangerous combination of several
types of radiation. In our case, it is
happening. After all, it is no secret
that the computer and the monitor / TV simultaneously irradiate 
us with you my electromagnetic flux. In addition,

the most dangerous computer rooms / classrooms
without special protection. To this very spetszaschite we
shall return shortly. Of the display wave uniformly distributed 
in all directions in radius of 1 to 2.5 meters. By the way, 
revealed the existence of a "computer incompatibility." What is 
it? Refers to those people who, because of individual

physiological and possibly psychological characteristics is 
generally not recommended work with a computer regardless of 
the degree protect the user from its radiation.



  Unfortunately, the few know it. If time does not reveal such
people, in what we can expect a very
deplorable results. Begin to identify, of course, must still 
"with mladye nails, and a we instead continue to "polls

computerization "of children.


  However, all too long - several hours a day - sitting
the computer is fraught with potential trouble with his health.


  Especially bad electromagnetic radiation of millimeter range, 
Kojima, and is computer-harmful side affects on allegrikov and 
persons with heart diseases.



  Ideally, to make your computer safe, while production in the 
body system units and monitors the internal

parties must bear a special screening layer, which reduces the 
electromagnetic radiation to the background values. And since 
so many of the currently available in Russian monitors provide 
enhanced danger, experts recommend necessarily apply filters to 
screen their compulsory grounding and shielding fabric of 
clothing. Yes! So that's clothing. The truth about these 
clothes is almost no one knows ... 


  However, first things first.


  1. The room where the computer is located,
should be sufficiently spacious and well
ventilated. Chairs, armchairs, sofas,
bed should not be placed within 2,5-3
meters around it.


  2. On the sides and back of the computer it is desirable to 
place a "green defense" of indoor plants. The most valuable 
from the point of protection are the cacti. Several

weaker than similar properties in aloe, agave,
primroses, cyclamen.


  3. The computer must be connected to the three-prong outlet. 
The fact that the third contact - this ground. If your 
workplace is not equipped with such sockets then either use a 
separate external ground (a simple wire to the battery central 
heating), and if the plug in you have three-pin, then use only

those adapters that are equipped with "land" wire.


  4. Along with optical glass or
plastic filter, computer screen
must be equipped with protective filter
mandatory grounding. You can, however,
using a filter that combines
all the necessary protective functions of optical filters.


  5. At work, operators are encouraged
wearing vests of shielding fabric.


  6. The computer screen should be at
distance of 45-70 cm from the operator and 20
degrees below eye level.


  7. Adults can sit at the computer
no more than four hours, resting after every 20-30 minutes. 
Schoolchildren 1-6 th grades - no longer than 10 minutes. 
Seven-and classmates - about 15-20 minutes. The total time of 
staying in front of a day for those and others - no more than 
an hour. Only older students can work in a row in 1925

minutes with 10-minute break, but no more
two hours a day.


  8. Teach your kids that all the games on the computer based 
on the speed and accuracy reaction, and not on the duration of 
sitting in front of the screen (even if it is not:). 


  9. After working on the computer at night is not
at least two to three hours refrain from
television viewing.

 10. Duration of work on the computer should be reduced prior 
to and during adverse geomagnetic conditions.


 11. Sitting in front of the screen, listen to
itself: the slightest discomfort, even mild
headache should be a signal to stop working. The principle of 
overcoming fraught with unpleasant consequences for your health.


 12. Work on the computer is contraindicated
people with weakened immune systems,
suffering from heart diseases and allergies, and pregnant women.

 13. Those who are going to become an operator, especially for 
people with impaired vision or nervous disorders, it is 
necessary consult with medical specialists. This is necessary 
in order to better understand the opportunities and the right 
dose load. 

 14. Women working on the computer
advised to make a cool shower for
face in the morning and evening, and the skin after him
wipe and allow to dry. Those who have
The skin is thin and dry, and red-haired
useful to apply on face for half an hour in the evening
nourishing cream.


  Still, I think there are among sinkleristov
Owners of cell phones, so for
You have some rules:


  1. Do not carry these phones in the inner pocket of his 
jacket. In an extreme case - outer side pocket, and even better 
- in case. In the soft-skinned, though ... :)



  2. Houses should not be put bezshnurovoy
telephone at the bedside.


  3. If you need a lot of time talking on his cell phone, be 
sure to Wear protective cap from the shield

tissue.


  But what the rules are in the home:


  1. Should not simultaneously include several household 
electrical appliances, capable of radiate electromagnetic waves.



  2. You can not put a TV with a small
screen in front of the bed, and sleep in
the TV, even if it is located at a distance of 1,5-2 meters.


  3. We should not sit closely behind or
the side of a TV, especially
left, where the television is block
line scan.


  4. When using a microwave oven
recommended that you purchase the device, registering the power 
of its radiation. Balancing furnace periodically violated, and 
if the radiation level increases dramatically. Having 
identified so, you must immediately call the master, who would 
wave back to normal. Without special training myself to do it 
in no way not!



  5. Furniture, especially beds, should be
placed no closer than 20-30 cm from the open
electrical cords and who connect
electrical outlet. Wires as
turned out to be too "noisy."


  6. It is not recommended to sit under the horns
chandeliers in the shape of a hemisphere facing down.
You can not hang lights sconce-like
forms over the head of the bed. In all cases, radiation lamps 
should be directed upwards.



  7. Can not be placed near the garden houses
transmission lines and transformer
booths.


  Of course, it's an ideal. In real life
many of these unattainable ...
