Tip 1: Are WiFi headphones harmful?

Wireless technology Wi-Fi serves to transferdata on the radio channel at high frequency. Thanks to it, it became possible to move freely while remaining connected to the Internet. Recently, people began to think about whether Wi-Fi technology is harmful to health.

The opinions of specialists in this regard are different. According to some of them, harm from Wi-Fi is a non-existent problem. By results of researches it has been established, that radiations from wireless devices below a normal level of radiation of habitual radio waves are 600 times. After the measurements were taken in one of the schools, it was found out that the radiation level emitted by wireless communication devices is three times lower than the radiation from mobile phones. In the light of these studies, we can say that the wireless networks of this standard are no more harmful to humans than mobile communications. Also experts say that at a wavelength of Wi-Fi equal to the wavelength of a microwave oven, the power of a wireless source is one hundred thousand times lower than that of an ordinary microwave oven. However, human body tissues located in close proximity to the source of Wi-Fi radiation can absorb it, and specially designed instructions are attached to the computer in this regard. However, other experts hint at the possibility of adverse effects of Wi-Fi on the human body. According to them, children are at particular risk because their nervous system is still at the stage of formation, and the bones of the skull are thinner than in adults. Scientists claim that the radiation sources in Wi-Fi devices are usually very small and not in close proximity to the human body. In response to the argument that some people hold the laptop on their lap, scientists notice that even in this case there is no danger to people. Children should be reminded that the device should be placed on the table, and not kept close to itself. There is an opinion that electromagnetic radiation from wireless devices in some people can still cause allergic reactions, a feeling of fatigue, headache, absent-mindedness and excessive irritability. All the same experts say that in this way, not all, but only about 30% of people in the so-called "electrosensitive" group react to wireless adapters and their radiation.

Tip 2: Harm to the microwave oven for human health

Microwave ovens were invented by German scientists as early as30-ies of the last century. The purpose of these simple kitchen appliances is to save precious time for cooking a particular food. In addition, in wartime, microwave ovens did not burden the German soldiers with the use of special fuel for furnaces. In the process of using microwave ovens it was found out that food, heated or cooked in them, has a negative effect on the health of German soldiers. This was the reason for the Germans' refusal to use new devices.

Microwaves have a negative effect on food and the body!

Is the microwave oven harmful to human health?

Today, microwave ovens occupy quite astrong positions in the kitchens of most housewives around the world. It is understandable: microwave ovens (microwave ovens) have become an indispensable tool if necessary to quickly warm up ready-made food, as well as good assistants in the preparation of light diet foods, in defrosting meat, etc. But this does not mean their safety. The harm caused by the microwave oven to the body is still troubling the inquisitive minds of mankind. It should be noted that these fears are not so groundless as it may seem at first glance. Recent studies conducted by specialists in this field have revealed several main reasons that testify to the harm of microwave ovens on the human body.

Factors of the negative effect of microwave ovens on the human body

Electromagnetic radiation. Harmful effects have electromagnetic radiation, or so-called torsion fields. The specialists checked a number of experiments, during which they found out that electromagnetic radiation contains a torsional component. It is the main factor of the negative influence of microwaves on the human body. A person can experience headaches, increased excitability or insomnia. Temperature. Another source of danger is the temperature emitted by these devices. It is curious that high-frequency radiation begins to heat the human body only with the constant and long use of the microwave oven. This thermal effect can lead to clouding and destruction of the lens of the eye. If you use this device for a short time and not for long, the emitted harmful temperature will not be. Nevertheless, the general harm from microwaves will not go anywhere! The effect of radiation on food. This is another factor that negatively affects the human body. As a result of intensive processing of food by microwave beams, so-called ionization of molecules can occur. This will entail a complete change in the structure of the substance. The fact is that a microwave oven is capable of creating new compounds that do not exist in nature. They are called radiolytical changes. They are provocateurs of the appearance of molecular rot. For example, microwave beams destroy vitamins C, B and E, and the value of food in general decreases by 60%. Radiation of the body. Among other things, microwave ovens have an enormous negative impact on the cells of the human body, destroying their structure, which leads to their inability to prevent the penetration of viruses and fungi into the body. Suppressed and the mechanism of natural cell regeneration. According to statistical data, irradiated food can cause malignant tumors in the human digestive system, and peripheral cellular tissue generally undergoes its degeneration, which leads to stomach upset. In conclusion, it should be noted that the most careful use of microwave ovens should be future mothers, since strong radiation from electromagnetic fields can provoke miscarriage, premature birth or the development of certain congenital malformations in the fetus.

Tip 3: Is the computer harmful to health?

An irreplaceable invention of mankind - a computer - performs a huge number of functions, due to which the life of a person is facilitated. But is this machine harmless, what is its danger?

Common problems when working at a computer

First of all, for a long time beforethe computer monitor has a worsening of the visual function. The constant voltage that occurs when focusing at the moment of the game or reading the pages, leads to deformation of the lens muscles. The second problem is frequent headaches. They arise because of disturbed venous outflow and stagnation of blood in the frontal, temporal and cervical muscles. Often, people whose activities are connected with work on the computer, the disease goes to a chronic form. Painful sensations in the neck, back - the third problem. Typically, they appear in the case if a person is in front of the computer for a long period of time without changing the pose. In addition, a constant sitting leads to a stagnant process in the pelvic region, which can lead to the formation of hemorrhoids. Arthritis and arthrosis of the hands is a common disease of computer scientists and programmers. With monotonous work with the mouse, the median nerve is compressed, which is responsible for the transmission of nerve impulses. At the first stage of the disease a person experiences a show and a slight numbness of the fingers, then a painful sensation and stiffness of movements appear.

How to reduce the risk of violations?

Of course, modern life is hard to imaginewithout this smart machine. Undoubtedly, harm from the computer is, if you are in front of the monitor a lot of time. To work at the computer did not cause a deterioration in human health, you must follow simple rules: - periodically change the pose and alternate sedentary work with active activity - if there is discomfort in the spine, make a five-minute charge, which will normalize blood flow and relieve muscle tension; regularly perform eye exercises (circular eyeball movements, alternation of focus on near and far objects) to relieve muscle spasms and reduce the risk - Use a special mouse pad with foam or helium inserts that prevent excessive bending of the brush. Thus, the health of the human body is completely dependent on the person himself. With a rational alternation of work and rest, with the observance of preventive measures, the negative impact of the computer is reduced to a minimum.

Tip 4: What harm from the headphones

Often in public places you can seea huge number of young people in the headphones who listen to their favorite music, without disturbing anyone. It would seem that headphones are a very convenient and useful invention, but is it safe for human health?

Danger of listening to music on headphones

American scientists are sure that the problems withhearing from young people and teenagers is not due to the fact that they listen to music on headphones, but because they include their favorite songs at a fairly high volume.

A child's hearing is more vulnerable than an adult, about thisshould be remembered even when using toy-rattles, which create a noise of about 110 decibels, thereby exceeding the volume of a simple conversation in half. If you have constant and long listening to music on headphones with such power, hearing loss may soon develop.

In addition, listening to your favorite tunes is badaffects not only the hearing, but also the nervous system and even the brain. This is justified by the fact that people, as a rule, include music at full capacity and listen to it for a long time. During this muscle, the ear canal constantly regulates the penetration of loud and abrupt sounds, and this in turn leads to their fatigue. At some point, the muscles no longer protect the inner ear. As a result, all sound impulses are transferred to the nervous system, irritating it.

Impact on mental work

It turns out that everything is more serious than it is commonly believed. Listening to songs in headphones can cause not only a decrease in hearing, but also dizziness, ringing in the ears, increased fatigue, overexcitation. And if a person does not feel very well, what kind of mental work can be talked about.

Young people and schoolchildren, who are prone to this not very useful habit, do not understand well, it is difficult for them to concentrate, as a result of which they lag behind their peers in academic performance.

So that it was not painfully painful then

Modern youth is quite difficultexplain or prohibit. But still it is better to take advantage of some tips that will help minimize the undesirable consequences of loud music and preserve your health.

Now on the shelves of stores there is simplya huge number of different models of headphones: vacuum, "mugs" and many others. It is best, of course, to choose those that would completely obscure the auricle. In addition, you should still pay attention to the fact that you can listen to music no more than 1,5-2 hours a day at a volume of not more than 50-70 percent. Otherwise, there will be problems with hearing.

Tip 5: Is the food from the microwave oven harmful?

Nowadays, the microwave oven usesEvery fifth family in Russia. When microwaves appeared in stores, along with them came a variety of horror stories. It is said that eating from a microwave oven leads to the development of cancer, that the waves emanating from the stove negatively affect pregnant women and the baby in the stomach, that food cooked in a microwave oven contains carcinogens in an overabundance.

A microwave oven is a household appliance that allowsThermally treat food with microwaves. These radio waves have a frequency of 2450 MHz. The wave, penetrating the product, causes the water molecules contained in the food to fluctuate. Thanks to this process, food is heated.

How does such an impact affect the veryProduct? There are no changes in the product itself when exposed to microwaves. Therefore, harmful or useful food after processing it in a microwave oven, will depend on the product originally placed in the oven.

If we compare, for example, products from a microwave oven withthose who have gone through the process of roasting, then those who are cooked in the microwave will be more healthy. Carcinogens are formed precisely when frying, and if they were not in the products before they were placed in a microwave oven, then there will not be any after.

The very process of processing products in the microwavevery close in its effect on cooking in a double boiler. The fact that when cooking is not necessary to add oil, makes the food from the microwave more healthy.

In terms of preserving vitamins in food, alsoit is worth giving preference to a microwave oven. In the process of cooking, up to sixty percent of the vitamins contained in the products are lost. And when using a microwave oven, not more than thirty percent. This is due to the fact that the process of cooking in the microwave takes less time.

Pros of using microwave ovens

Microwave is convenient in everyday life. The stove can easily be used by a child.
After work, there is the opportunity to warm up or cook food without spending a lot of time and energy on it.
It is also very convenient to use a microwave when defrosting the food.
The power consumption of a microwave oven is almost half that of an electric stove.
No special microwave utensils are required. You can take advantage of what's already there, most importantly, that the dishes are not made of metal.

One way or another, in all is important a reasonable balance. If you harmoniously combine food intake from a microwave oven with fresh fruits and vegetables, then you should not worry.
