Sources of risk in a computer are concentrated in two sources: the display screen, the other, the sitting position, and the way the mouse is used "Mause" and the "Keyboard".

And the danger of the computer screen to health lies in the difference in the radiation from the screen, which is considered harmful to the individual, especially sitting for long periods in front of it, and in case of dealing with the computer screen in a negative way, the size of the health damages resulting from it increases.

And the types of rays issued from the computer screen are diverse and that affect human skin and its freshness.

A new American study found that caffeine in coffee reduces the risk of cirrhosis in patients with hepatitis C.

Baldness, which affects many men and worries them in their youth, was found to protect men from prostate cancer.

In this issue, American scientists discovered that eating a certain chemical may help get rid of obesity.

The increasing spread of the computer and its transformation into a fixed daily part of the practical and personal life of many people around the world has led to the emergence of many health problems associated with this.

Computer and eye screen

It has spread due to sitting and working in front of computer screens, health problems and inconveniences that cause eye fatigue and headache after using the computer for relatively long periods.

Among the symptoms that computer users complain of are the following:

Pain, burning or dry eyes.

Double or blurry vision.

Headache and headache.

Neck and shoulder pain.

Increased sensitivity to light.

Difficulty moving the focus of the eyes from the screen to other things.

Although documented medical studies have not yet proven conclusively that long-term use of a computer has lasting negative effects on human health, the symptoms and pain associated with that remain disturbing in themselves.

So it is useful for the computer user to follow simple methods that reduce these symptoms.

Computer screen specifications

The screen should be at a distance of 45-75 centimeters from the eye and the computer user can use his arm length as a quick gauge to determine the appropriate dimension to his eyes from the screen.

The top end of the screen should be at or below the eyes level slightly, because the height of the screen above that will lead to the user having to bend his neck to the back, which will lead to the prolonged use of the neck and shoulders.

Screen glare

Care must be taken to clean the screen from dust, because it can intensify it, which may lead to increased glare and light reflections.

The user must also ensure that the computer screen is not in the direct direction of the fall of the window light or headlights.

Also, the screen should not be facing the window itself either (i.e. the window is located behind the screen).

Studies say that the right place is for the window to be to the right or left of the screen, not behind or in front of it.

The user can know the sources of light reflection by turning off the screen and watching the reflected glare from its black page, and then adjusting its position and angle until this glow reduces to a minimum.

Dealing with a computer screen

The computer user should make sure to look up from the computer screen at a rate of at least every ten minutes and to look at any remote scene (through the window for example) in order to change the focus distance of the eyes, which will reduce the pressure on the visual muscles.

It is normal for a person to blink with his eyes once every five seconds, and the longer the period, the more likely the eyes will dry out.

Therefore, the computer user, especially those who wear contact lenses, must be careful to blink always while using the computer so that his eyeballs do not dry out and his feeling of burning and pain begins.

It is advised that the computer user rest his head back between now and then and that his eyelids close for a little time, which gives the eye a sufficient opportunity to moisten with tears and to relax its muscles.

Place reading material

Care should be taken to place any papers or materials that the user reads while working on the computer on a paper holder that is next to the screen and with the same high level of vision, so as to reduce the effort on the eyes due to the different focus distances.

It is assumed that if you follow the previous instructions, it will reduce the stress and pain arising from the use of the computer screen. The specialist doctor should be consulted when symptoms persist and the pain increases.

The effect of the screen on the skin

Sitting for a long time in front of a computer screen leads to pale skin tone and an increase in the secretion of sebaceous glands in it as the skin acquires an oily layer, which leads to redness of the skin color.

As for the owners of oily skin who suffer from «acne» disease, their severity increases especially in the area of ​​the cheeks, forehead and nose.

These rays issued by the screen lead to a prolonged period of sitting in front of them leading to the appearance of facial wrinkles early around the eyes, mouth and forehead, which means aging skin and premature skin.

These symptoms that occur when exposed to computer screen rays may be caused by the static electric charge present on the computer user's body in humid conditions and these charges will lead to deposition of air components and thus the occurrence of skin allergy.

The rays from the screen

The types of rays issued by the computer screen are the following types:

• Electromagnetic radiation.

• UV.

• X ray.

• Infrared.

Among the most prominent damages caused by these rays is the suppression of the hormone melatonin, and thus immune deficiency and the reduction of the activities of neurotransmitters, which leads to weakening the ability to focus in the various daily activities of the human being.

To avoid damage to computer rays on the skin and skin, you can follow health instructions and easy medical advice, which is the following:

Reducing the number of hours that we sit in front of a computer screen.

• Putting sunscreen on the face skin when sitting in front of the computer screen, whether it is sitting for long periods of time or short periods, especially for girls.

Reducing the percentage of illumination from the screen.
