If you sit a lot, what will happen. Impact on children. Comfortable chairs don't work

Life modern man hard to imagine without a computer.

This is entertainment, and a means of communication, and business, and work.

It is somehow strange to see a threat in such familiar equipment, but it exists.

How long you can sit at a computer directly depends on age, nature of work and knowledge of the basics of health.

How long can you sit at the computer and why is it dangerous

If older people became friends with computers, what can we say about young people and teenagers? It is unlikely that they imagine their existence without monitors, tablets and the virtual world. Moreover, if some people work with computers, then others spend their free time in virtuality all the time, playing or talking for hours. Both take risks.

First of all, electromagnetic radiation is dangerous, which can cause chronic fatigue, headache, increased nervousness, decrease immune protection organism. A constantly exposed person is at risk for oncological diseases. The radiation acts in a rather large radius of one and a half meters from the monitor, so that harm is done to the user himself and to the people around him.

Of course, manufacturers are seriously engaged in screen protection in order to reduce the radiation power from the monitor. But what to do with other parts of the monitor, as well as the system unit? All of them are also sources of radiation.

Do not rely on the safety of laptops: they radiate, and how! Moreover, laptops are closest to human body, which clearly does not reduce the degree of danger.

Radiation affects children more than adults. Their skull bones are thinner, and the medulla is more conductive. Hence the harm that a computer (or rather, radiation) can cause at the stage of embryonic development, from miscarriage to fetal pathology. How long can a pregnant woman sit at a computer? Do I need to explain...

Increased load on the eyes - the second serious problem associated with computers. Yes, there is no obvious harmful flickering that the first monitors sinned about today, and the load on the eyes is akin to that given by an ordinary TV. But uncontrolled time spent at the monitor is fraught with overstrain. optic nerve, decreased vision, the development of myopia - myopia.

The computer is especially dangerous for children who already have visual impairment. It is the eyes that suffer in the first place if a person does not observe the elementary mode of working with the monitor.

The question of how long you can sit at the computer directly relates to the development of varicose veins, scoliosis and osteochondrosis. If an adult or a child sits in front of the monitor for hours, blood circulation in the pelvic organs will be disturbed. The habit of snacking without leaving the workplace or the playing field leads to obesity, potentially dangerous in terms of developing problems with the heart, blood vessels, hormonal system.

If the child has a curvature spinal column It's impossible to deal with the problem on your own. It is necessary to treat scoliosis in a complex way: daily gymnastics, massage, constant control posture, swimming

You should not discount such an important point as the development of computer addiction, similar to alcohol and drug addiction. It can also appear in an adult, but children are most often affected. Closedness, lack of interests and friends in real world, sociopathy, a shattered nervous system - such is the retribution for the time spent at the monitor. In adults, against the background of complete immersion in virtual world insomnia often develops, which interferes with full-fledged work and rest.

How long can you sit at the computer: instructions for adults and children

It is easy to understand that the question of how long you can sit at the computer, and the answer suggests itself: the less, the better. However, there are specific medical advice according to which you should plan your work and leisure.

Adult users should be guided the following rules:

Work at the monitor for no more than two hours in a row;

Do visual gymnastics every half hour;

After two hours of work, be sure to take a break for at least twenty minutes. To break means to get up, walk, do exercises to disperse the blood in the legs and pelvic region;

In total, an adult can spend no more than six hours at a computer per day. Exceeding this limit is fraught with the occurrence serious problems with health.

The norms for children to stay in front of the monitor are even more stringent. How long you can sit at the computer depends primarily on the age of the child. Until he is five years old, he cannot be allowed behind the monitor. In the future, you should follow following recommendations ophthalmologists:

Children of senior preschool and junior school age up to ten years can spend at the computer no more than half an hour a day, while one session should not exceed ten minutes;

Children from ten to 14 years old can work for about an hour, taking a mandatory break every twenty minutes;

From 15 years old to adulthood total time can be increased by another half an hour a day.

If the computer explicitly provides pernicious influence on the health of the child, it is necessary to exclude him from the life of the student.

How long can you sit at the computer and how to reduce harm

Adults often ignore the recommendation to take an active break from working at the computer, but in vain. Just looking away from the monitor is not enough: in order to minimize harm to your health, you just need to walk, ideally take a short walk in the fresh air.

Visual gymnastics also very important component maintaining health. What can be done:

Close your eyes and sit like this for a few minutes;

Make rotational movements eyeballs in different directions, then up and down;

Looking out the window, first look at a point in it, and then, without changing the position of the head, look further behind the glass, at an object in the long term. Work with focus close-far several times.

How long you can sit at the computer also depends on how well the workplace is organized. You should adjust the height of the chair and table, the position of the monitor, be sure to provide good, even lighting, and the source should not be near the monitor. Every two hours you need to ventilate the room. By following all these rules, you can really reduce the harm from working with computer equipment.

When sitting, the pressure inside the discs is higher than when standing or lying down. The sacrum diverges to the sides under the weight of the spine, and its base in the middle is compressed, as in a vise. Over time, the fluid from the discs seeps out (they lose about 10% of moisture), and the bone segments, located one above the other, turn into a rigid tube. Most of liquid leaks out during the first two hours of sitting, but the discs dry out faster the longer they remain compressed. People who work long hours while sitting usually feel back discomfort when they get up. Sometimes it takes a few minutes before the base of the spine drops and movement becomes easier. If prolonged sitting is accompanied by insufficient mobility, the lower discs never recover normally and this is where it starts from sedentary work back hurt.

Self-healing exercises

The discs fill with fluid faster than they take it out. This is partly due to the concentration of electrolytes in the nucleus pulposus, which draws water under osmotic pressure, and in part - with a retracting effect from stretching the spine. The discs fill faster if you lie on your back with your knees drawn up to the work; that is why such a simple exercise - main part self-treatment. Raising the knees to the chest and squatting prevents disc fluid loss by opening up the posterior spinal complex.

And the use of a special block for the back reveals the anterior complex of the spine. With its help, the spine is additionally stretched, due to which not only the front surfaces of the discs open, absorbing fluid, but also an excessively clamped posture when sitting is compensated. The block must be used every day. You will love the feeling of the segments being stretched as you can almost feel the disc walls rebuilding and water being sucked in from the vertebral bodies.

Why is it bad to sit for a long time?

Sitting for long periods of time can also shorten other structures in your lumbosacral region, making it even more difficult for you to assume a normal posture. For example, powerful muscles - the flexors on the front of the thigh - are quickly shortened if for a long time are not involved. This causes a feeling of tightness in the front of the thighs. This forces the person to tilt the pelvis forward, causing the spine to lose balance.

Shortened hip flexors also force us to take shorter steps because the legs cannot flex properly at the hips. And this, in turn, again has a bad effect on the work of the spine, because when walking, he has to turn to the sides in order to compensate for the lack of hip mobility.

If you sit with your back hunched, it causes contracture of the anterior longitudinal ligament of the spine, which runs along the vertebral bodies like a long elastic band.

In the normal state, the function of this ligament is to limit the deflection of the spine, but when it shortens adaptively, it draws the spine in an arc from the front, like a bowstring pulled too tight. A person often feels that his posture is deteriorating and something prevents him from straightening up, as if his shirt is tucked too tightly in front of his trousers. The back block will help you get rid of the troubles caused by prolonged sitting. It straightens the spine and chest, normalizes the position of the pelvis, and if you lower your legs to the floor, then it stretches the muscles on the front side of the thigh. But, more importantly, thanks to it, the compression of the spine is eliminated, the compacted walls of the discs are stretched, and the fluid is freely absorbed inside.

What is important to remember!

Remember that sitting on a chair is an absolutely unnatural posture for our body. Many natives prefer to squat rather than use a chair with a back. Even if during the day they run a lot or carry weights - both of these actions squeeze the base of the spine - they easily eliminate this problem by squatting food and eating it in the same position. You never see a Maasai warrior lounging on a couch. Squatting is obligatory part self-treatment programs.

What happens if you sit in a chair for a long time at work

In people engaged in sedentary work, some segments in the lower part of the spine lose their mobility. If you sit hunched over in a chair with your legs crossed and the telephone handset pressed to your ear, the whole body will become stiff and the disks in the lower part of the spine will dry out. Most often, such problems occur among those who work at a computer and among representatives of other "sedentary" professions. Over time, the body from sitting is clamped faster and faster, and straightening it, rising from a chair, becomes more and more difficult; constant stiffness in the lower back turns into a clear problem.

Drivers at risk

Truck drivers and taxi drivers also often suffer from pain in the lumbosacral region. Not only a sitting posture, but also the constant vibration of the car increase the loss of fluid from the lower discs. It is even worse if the cab is high up and the driver is forced to jump to the ground. The push is especially unfavorable when the back is already clamped. The situation becomes especially dangerous if, during loading or unloading, he has to lift and carry heavy loads.

Global computerization is an undeniable technical progress. Older people can also work on a computer, and even two year olds something their parents are incredibly proud of. Both children and teenagers are ready to spend all day and night behind an inviting monitor.

At the same time, few people think about where children's tantrums suddenly come from, why teenagers suffer from headaches, and where healthy, unburdened children come from.

It is completely impossible to give up the computer, because in the modern technogenic world, the PC has become an indispensable element of life. But, like any technical gadget, the computer must be used wisely, strictly observing the time, conditions and breaks in work.

The harm to health caused by a computer is sometimes exaggerated. The negative impact is created due to the non-normalized time of work at the PC, i.e. the person himself exacerbates the existing risks.

Electromagnetic radiation

Any household appliance emits EMP, but a person does not sleep next to a refrigerator or a working microwave oven, does not watch TV at a distance of 25-40 cm from the eyes, but when working at a PC, all emitters are concentrated near the body: monitor, operating unit, mouse, keyboard.

An independent study of computers distributed on the market for these products, which was conducted by employees of the Center for EM Security (Moscow), made it possible to draw a disappointing conclusion about the excess of biologically dangerous level EMP in the user's area.

PCs increase the overall EM background created by household appliances and "irradiate" not only the person sitting at the screen, but also those around them. An area within a radius of 1.5 m from the computer is considered hazardous.

Increased EMR background causes:

headache
fatigue, nervousness
reduced resistance to infections, from the skin to the internal organs
in an increase in the number malignant neoplasms the increased EM background also makes its undeniable contribution.

PC monitors made on cathode ray tubes

They are proven sources of ultraviolet, soft X-ray, visible, infrared, radio frequency, microwave and low frequency EMP. Most of all, EMR is emitted by the rear and side walls of the monitor. Every year more stringent standards are adopted regarding the radiation power of the monitor, while manufacturers take a tricky step, not reducing this very power, but improving the quality of the protective coating applied to front part screen. The rear and side walls still emit EMP.

System unit

The system unit is also a powerful emitter. The human body is most sensitive to EMR in the range of 40-70 GHz. At these frequencies, the wavelength is commensurate with the size of the cells, which means that the radiation easily penetrates the tissues. Features of modern PCs:

this is an increase in the operating frequencies of both the processor and peripheral devices
power increase up to 400 - 500 watts.

As a result, the radiation level of the block in the frequency range of 40-70 GHz has increased thousands of times over the past 2-3 years.

Laptop and LCD monitors

LCD monitors and laptops based on liquid crystals are positioned as safe, because they do not generate the “bouquet” of EMR characteristic of cathode ray tubes. But not only the tube is an emitter - the power supply voltage converter is also capable of generating harmful fields when the device is operating from the network, and the control circuit, and other elements of the equipment.

At the same time, the laptop is always located closer to the user, and some users have a habit of placing the PC on their laps.

Research: The testing centers "CYCLONE-TEST" and "ELITE" investigated 5 types of laptops from the most famous manufacturers. The EMI measurement was carried out in 8 directions from the equipment, including the keyboard, since it is monolithically connected to the laptop. In this case, the measurement distances from the PC were taken smaller than those specified by the MPR II standard.

Studies have shown that when the device was powered both from the mains and from the battery, the MPR II standards were not met for most samples in all 8 directions. Especially significant excess observed in front and to the right of PC.

The impact of EMR on children and pregnant women

The brain substance in children is more conductive, and the bones of the skull are thinner, which leads to a greater specific absorbed power in the end. EMR penetrates deeper into parts of the brain.

EMT is a biologically active factor in relation to embryos. As is known, the sensitivity of an embryo to any damaging factors is several times higher than that of an adult, and EMR is no exception. Intrauterine damage while working at a computer most often occurs on early stages development, which leads to miscarriages or malformations.

Vision

Modern monitors are already devoid of the previously characteristic problem - flickering, but this does not mean that the computer does not exert strain on the eyes, which, subject to the standard operating time on a PC, is comparable to that when watching TV.

Stress is the uncontrolled use of a computer by children whose health is rare cases is absolute, leads to tension visual apparatus, which equates to severe stress. Everyone knows about the consequences of stress, this is a separate issue.
Decreased vision - weakness of the muscular apparatus of the eyes during overstrain leads to a drop in vision. Fascinated by the picture on the monitor, children forget to blink, which leads to dryness of the cornea and deterioration of vision.

Four factors affect the final eye strain:

monitor quality;
work intensity;
duration of work;
workplace organization.

The screen image is a priori different from the natural one. Unlike natural reflected light, it is self-luminous and has little contrast, which is further reduced by external light. The image from the monitor consists of individual dots, constantly flickering. There are no clear boundaries, like a picture on paper, in a computer image.

The increase in visual load is accompanied by the need to constantly move your eyes from the screen to paper text or the keyboard. The situation is aggravated by poor quality software, incongruous color matching, unreadable font, poor monitor location, poorly organized workplace (glare from the screen, non-observance of the distance to the screen, etc.).

All this leads to the development of the so-called computer visual syndrome:

eyes start to water
the image becomes fuzzy, double
fatigue occurs
concentration change.

Examination of people working at a computer for a long time led to the identification of the following symptoms:

eye redness in 48%;
itching of the periocular region in 41%;
eye pain in 9%;
"flies" in the eyes of 36%;
discomfort in 5-10%;
headache in 9%;
weakness at 3%;
darkening and double vision in 2 - 0.16%;

In addition to subjective sensations, this group of people also observed physiological changes in the visual system:

violation of convergence in 52% of cases, accommodation - in 45% of users;
change binocular vision in 49%, stereovision - in 47%;
decrease in visual acuity in 34%.

Sitting position

Prolonged sitting at a computer forced posture turns into stagnation of blood in the pelvic area, contributing to the development.
Stress on musculoskeletal system leading to postural problems and scoliosis childhood, as well as the deposition of salts and osteochondrosis in adults.
Hypodynamia leads to muscle weakness, obesity. A sedentary lifestyle of a person leads to already 35-40 years of age, which is threatened by heart attacks and strokes.

As for children, the problem is more than serious. Parents who are faced with problematic posture in their children know that it is very difficult to stop the progression and cure the curvature of the spine that has begun. The computer is taking over children's attention, the child does not feel that he is sitting, hunched over. Pathological process very quickly starts in a growing child's body:

at first there is a barely noticeable stoop
it is more difficult for the child to keep his back straight
in sitting position the back becomes round
then muscle weakness and incorrect posture lead to a curvature of the spinal column, which can progress literally before our eyes.

Load on the joints of the hands

Many people notice that after long work on a computer (with a keyboard or mouse), the hand begins to go numb, especially in the area of \u200b\u200bthe fingertips, and also ache. I want to rub my hands all the time, as if they are numb. All of this is the result of a malfunction. small joints hand, blood supply and innervation.

Exposure to dust, dirt and chemicals

During operation, the PC attracts dust and various dirt, which accumulates in the system unit, settles on the keyboard and mouse. The PC cooling system causes dust to circulate indoors.

It is proved that the keyboard contains at times more germs than on the toilet lid.
Dust, being an active allergen, leads to the development of hypersensitivity reactions, and. In its turn, pathogenic microorganisms fall from dirty hands into the body and cause various obvious or latent infections.

Swedish environmentalists have found that within two years after manufacture, the monitor releases into the air chemical compound triphenyl phosphate, which is strong allergen. This substance is part of the plastic, and when the latter is heated during the operation of the PC, it begins to be released into the air. The level of triphenyl phosphate is ten times higher than background while working on a PC.

Influence on the nervous system and psyche

This factor is the most dangerous and in some cases leads to irreversible consequences and the formation of complete mental dependence on the computer.

Impact on children

Unstable children's and teenage psyche suffers from being addicted to the computer. Problems begin with a simple reluctance to leave the computer to do the usual things (walk, eat). Then the child refuses to go to bed at the allotted time.

In the future, the deprivation of the computer leads to irritability and tantrums. There is a violation of attention and memory, depressive and even aggressive mood.

Taste for life and mood return only while playing on PC. At the same time, the child is not interested in the environment and what is happening, addressing him during computer games causes aggression or goes unnoticed. AT literally addicted children get into the computer world, becoming zombies and not interested in real life.

Impact on adults

Adult users often run away from their problems, plunging into the virtual world and being already there the winner of life. At the same time, the events of the game are perceived as in reality, with feelings and emotions. The adrenaline produced during the game is not destroyed by the body, as it happens when playing sports, cycling, etc. Increasing in the body, adrenaline leads to the destruction of the nervous system, the development of neurasthenia and psychosis.

And for those who already have mental problems, the computer is absolutely contraindicated. Having tasted the taste of murder during the game, such people easily decide on this act in real life including suicide. famous case the suicide of 6 Russian schoolchildren - fans of the "Final Fantasy", which occurred in 2001, is far from the only one, the sad statistics are constantly replenished with the ridiculous deaths of people dependent on computers.

Computer addiction in its strength is equated to alcohol or drug addiction! But if, in the case of the last two, various methods struggle, starting from the state level, then gamers remain on the sidelines, destroying their lives and the fate of their loved ones.

Is radiation from a Wi-Fi router harmful?

There is probably a wireless access point to the global network in every apartment. It is convenient and economical, and those who switched to Wi-Fi are unlikely to return to wired Internet.

The radiation frequency of the router is 2.4 GHz (a little more for a microwave oven).
Radiation power - 18 mW (for a mobile phone, about 1 W.
If the device is turned on constantly, accordingly, the impact on a person will also be constant. Some people do not turn off the access point even at night, they sleep in the room where the router is located, which is completely unacceptable.
An excess of radio waves threatens the development of irritability, fatigue and other symptoms.

Operating at a fairly high frequency, the router has low power. Those. reasonable use of the device, placed at a safe distance, outside the sleeping quarters is considered acceptable and is comparable to the operation of a TV, refrigerator and other EMP emitting devices. The closer the cure generator (in our case, the router) is located to the person, the longer it works in continuous mode, the greater Negative influence he renders.

At public places WiFi access Free source is far away from users without affecting health. AT this case more radiates the device with which Internet access is carried out (phone, tablet).

Rules for working on a personal computer

All of the problems listed above can be avoided by strictly following the rules of working on a PC yourself and not giving concessions to children, allowing them to play “well, another 5 minutes”.

Working hours on a PC - how long can you sit at a computer

For adult users, the total time on the PC is 6 hours per day (maximum can be sitting at the computer for 8 hours, due to professional need). This does not mean that you can sit down at the computer at 9 am and sit non-stop until 3 pm. Breaks must be respected, which we will discuss below.

Adolescents 12-16 years old can spend no more than 2 hours at the PC a day;
Children 7-10 years old-12 years old are allowed 1 hour of work on a PC;
A child of 5-7 years old can sit at a computer for no more than half an hour.
For kids under 5 years old, the PC should be banned.

Scheduled breaks

In order not to develop an overload of organs and systems, as well as mental discomfort, it is necessary to interrupt leisure. Those. simply turning away from the monitor and looking out the window is not an option.

During each working hour, after 15-20 minutes, you should take your eyes off the screen for 2-3 minutes or at least close them, doing a mini-unloading of the visual analyzer.
After every 45 minutes of working on a PC, you need to take a 10-15 minute break: warm up, walk around. If possible, you can lie down with your eyes closed.
After 3 hours of work, you need to break for a half-hour rest - go for a walk, breathe fresh air, have a snack.
It is useful to do gymnastics for the eyes - rotation of the eyeballs, frequent blinking, shifting the gaze from near to distant objects.

Organization of the workplace - how to sit at the computer

To work on a PC, there must be appropriate furniture - a computer table and a chair. Both adult and children's furniture is produced, which can be adjusted in accordance with growth. The height of the chair must match the height of the table.

The lighting should be even, there should be no contrasting light sources next to the monitor.
The best option for placing the monitor is in the corner of the room, which will allow the walls to absorb the EMP it generates. The distance to the monitor should be from 40-50 cm, while it should occupy a position a few cm below the eyes so that the look at the monitor is from top to bottom, and not vice versa. The refresh rate of the monitor screen must be at least 85 Hz.
The system unit should be located at the maximum distance from the person.

To work on a PC, special protective glasses are sold, which in no way affect the quality of the picture, but protect the eyes from overstrain.

Computer care

At least once a month, you need to remove the back cover of the system unit and gently vacuum the parts. Keyboard and monitor should be cleaned by special means everyday.

To prevent the unused computer from generating harmful radiation, you should turn it off from the network. This rule also applies to wireless or wired Internet routers - they must be turned off.

Indoor microclimate

During breaks in work, cross-ventilation of the room should be done, and during work, keep the window on micro-ventilation. The work of the PC leads to an increase in the level of positively charged and a decrease in negatively charged ions.

Fifteen minute airing leads this indicator back to normal. During airing, other people also leave the room. chemical substances released into the air due to the operation of the PC.

How to save a child from computer addiction or prevent it from forming

It is difficult to completely exclude a computer for a student, but health should always remain a priority! The PC must be used strictly for homework and under adult supervision. If you give up slack and let you play the game after completing homework on a PC, you can forget about the further productive implementation of lessons. Tasks that involve working on a PC should be done last.
The computer should never be positioned as a bonus for something. It is impossible to turn a computer into a super-forbidden one (it is always more attractive), just as one cannot turn a PC into a cult and an incentive prize for obedience. The child must understand that a computer is a gadget for adults.
Try to take all the free time of the child to good use: let it be sports sections, circles, swimming pool, dancing, gymnastics, hockey and others. Giving energy to useful pastime, there will simply not be enough time for a computer.
Don't apply bad example, enthusiastically fighting space monsters in front of children. Let the computer be associated with work necessity, not entertainment.
Spend time with children, excluding the moments when the child is sitting at the computer and left to himself, without distracting adults from their daily activities. Games should be in the life of a child, because they develop, but let them be active street or exciting board games that are so much fun to play with the whole family.
Start introducing children to the computer world not immediately from an adult PC or laptop, if a child wants a computer, buy him a toy educational device similar to appearance with a laptop.

A computer and human health are contradictory concepts, but with a reasonable organization of work on a PC, you can minimize bad influence health devices.

The most common problems that a sedentary person can reward us with inactive image life is problems with the spine. Basically, the emphasis is on posture problems, pain in the shoulders, neck, back and headaches. But the bonuses don't end there.

This also includes problems with the lungs, heart and stomach. Do you want to know what happens to your body when you stay too long at work or on your favorite couch watching TV?

Head

Blood clots that form as a result of long, immobile sitting can travel through circulatory system and reach the brain, causing a stroke.

This can also include headaches caused by poor blood flow and problems with the neck and spine. Due to headaches, concentration worsens, vision problems may occur.

Fluid that is retained in your legs from a day of sitting moves into your neck when you lie down, that is, go to bed. And can cause obstructive sleep apnea - sudden stop breathing.

Previously, problems with sleep apnea were associated with obesity, but according to medical data, about 60% of people suffering from this syndrome did not suffer from overweight. According to latest study, conducted by Canadian scientists, it turned out that in people who spend almost their entire working day sitting, fluid accumulates in their legs, which then moves to the neck when a person assumes a horizontal position (that is, sleeps). This fluid is the cause of nighttime breathing problems.

Heart

A sedentary lifestyle can lead to cardiovascular diseases. In people who suffer from heart failure and obstructive sleep apnea, fluid builds up in the lungs and neck at night.

Lungs

In people suffering from heart failure and other heart problems, fluid can build up in the lungs, leading to breathing problems. You can also add pulmonary embolism here. The problem is even more annoying than its name.

Stomach

sedentary and sedentary image life can lead to obesity and problems with gastrointestinal tract(up to colon cancer). Enzymes that are responsible for muscle function blood vessels, which, in turn, are responsible for burning fat, are turned off. And the way metabolism is regulated, by which the body burns its fuel (especially glucose and lipids), goes astray.

As a result, your butt takes the shape and size of your desk chair.

Here you can add constipation, hemorrhoids and "other joys of life."

Legs

As mentioned above, during prolonged sitting, fluid accumulates in the legs, which leads to swelling. Another problem is varicose veins.

The most common problems that a sedentary, inactive lifestyle can reward us with are spinal problems. Basically, the emphasis is on posture problems, pain in the shoulders, neck, back and headaches. But the bonuses don't end there.

This also includes problems with the lungs, heart and stomach. Do you want to know what happens to your body when you stay too long at work or on your favorite couch watching TV?

A few days later, the redness disappeared. You meet with the doctor in two weeks. You started racing again. You don't have any specific symptoms. There remains doubt about the condition of your arteries, but it should not be so serious. I'm glad to see that everything is going well. -Me too. Do not worry about it. "Shouldn't we monitor the electrocardiogram?". Thank you Doctor. "Not that." So, where is the "hit" in this story?

Recently there was a very interesting symposium in Montreal organized by the Medical Association of Quebec dealing with this growing problem. On this day, a very important initiative was launched: the Choice of Care campaign, which aims to educate physicians, other professionals and patients about the problems of overdiagnosis.

Head

Blood clots that form as a result of long, immobile sitting can travel through the circulatory system and reach the brain, causing a stroke.

This can also include headaches caused by poor blood flow and problems with the neck and spine. Due to headaches, concentration worsens, vision problems may occur.

By the way, blow, there is one: we are probably spending billions for nothing - on tests, blood tests and treatments that do not work. real influence to our health. The sometimes false belief that it is better to diagnose and treat anything related is widely held by doctors and patients alike.

the only important measures in medicine are those that allow you to extend the service life or improve its quality. Whenever a doctor makes a diagnosis or gives a remedy, he should ask this question. Back to my story, which is pretty banal, what's wrong?

Fluid that is retained in your legs from a day of sitting moves into your neck when you lie down, that is, go to bed. And it can cause obstructive sleep apnea - a sudden stoppage of breathing.

Previously, problems with sleep apnea were associated with obesity, but according to medical data, about 60% of people suffering from this syndrome were not overweight. According to the latest study conducted by Canadian scientists, it turned out that in people who spend almost their entire working day sitting, fluid accumulates in their legs, which then moves to the neck when a person takes a horizontal position (that is, sleeps). This fluid is the cause of nighttime breathing problems.

First, there was no indication that an electrocardiogram should be given to an asymptomatic active patient. The test was perhaps a little abnormal, but that doesn't mean much if the patient is young. No doubt he wouldn't need a conveyor belt.

Because the Treadmill not quite normal, it is required to "calm down" the exam for nuclear medicine. But sometimes this is not normal, even without an underlying disease. Aspirin is added for prevention, and nitro is prescribed. But nitro can have a side effect that causes sharp drop pressure. Therefore, we are caught with a loss of consciousness that could cause injuries. And, above all, the clinical situation, whose apparent gravity has only increased, while basically there is no real symptom.

Heart

A sedentary lifestyle can lead to cardiovascular disease. In people who suffer from heart failure and obstructive sleep apnea, fluid builds up in the lungs and neck at night.

Lungs

In people suffering from heart failure and other heart problems, fluid can build up in the lungs, leading to breathing problems. This can also include pulmonary embolism. The problem is even more annoying than its name.

In the department emergency care with a history of abnormal chest pain and nuclear medicine a focus on coronary angiography becomes almost mandatory. Fortunately, in addition to drug allergies, serious complications did not have. Because no examination is safe.

The medical profession must make the problem of overdiagnosis a major issue for reflection and learning, not just economic reasons. Because often, caring for less attention means best care. Dr. Allen Wadboncoeur is an emergency physician and head of the emergency department at the Montreal Heart Institute. Associate Professor at the University of Montreal, he teaches health care management and is regularly involved in health research.

Stomach

A sedentary and sedentary lifestyle can lead to obesity and problems with the gastrointestinal tract (up to colon cancer). Enzymes that are responsible for the functioning of the muscles of the blood vessels, which, in turn, are responsible for burning fat, are turned off. And the way metabolism is regulated, by which the body burns its fuel (especially glucose and lipids), goes astray.

It connects us to others, it's hyper practical and, if we use it wisely, it can even appease us. But you know that we shouldn't abuse good deeds. It's no secret that shutting down from time to time can do a lot of good.

However, we spend more time chained to our screens and it is found that this heavy use negatively affects our health. The following is a partial list of effects on the body and mind. Perhaps it's time to take a break. The study found that tilting his head 60 degrees forward to watch his phone was the equivalent of nearly 30 pounds of pressure on his neck muscles. Other studies have shown that sitting in front of a computer all day long can affect our posture.

As a result, your butt takes the shape and size of your desk chair.

Here you can add constipation, hemorrhoids and "other joys of life."

Legs

As mentioned above, during prolonged sitting, fluid accumulates in the legs, which leads to swelling. Another problem is varicose veins.

Arms

It's disgusting, but it's the stark truth: our cell phones are rife with bacteria. The germs that build up on our mobile phones can cause acne or eczema, Daily Health says. Fortunately, the solution is very simple. Experts suggest cleaning and sterilizing your phone and making the most of your hands-free kit.

Laptops are really handy, but the people who put them on their laps may be playing with their ancestral heritage. This doesn't just apply to computers. A recent meta-analysis by researchers at the University of Exeter in the UK suggests that people who put their cell phone in their pockets are exposed to levels of radiation that can reduce sperm count.

Carpal tunnel syndrome is one of the most unpleasant consequences. If you try to bend your hand so that there is an angle of at least 90 degrees between it and your hand, you will feel sharp pain. Not to mention that the wrists will just whine on their own (I know from my own experience). In particular advanced cases requires pumping fluid from the joints - the procedure is not very pleasant.

It doesn't matter the medical diagnosis, but the symptoms are real. Repeated physical activity- for example, squeezing your phone - can cause muscle tension or aggravate problems like tendinitis. It may also cause pain in the forearm or wrist.

When we were little and someone saw us sleeping, we pretended that our eyes "just needed to rest." It may have been a false excuse at the time, but it's important that you spend your days in front of a computer. If you connect the monitor for too long, eye strain may headache. Reading black characters on a bright screen can cause a spasm in the temples.

This is a small reminder of what can happen to you if you prefer a couch vacation to an active one, even if you are terribly tired at work and just fall off your feet. Do not be lazy to walk an extra stop on foot - go to work 10 minutes earlier. Don't stay for lunch at the office: the walk to the cafe is also a walk.

To reduce pain, adjust the contrast of your screens. You've heard of hypochondriacs, but did you know there are "cyber conductors"? It seems to pull hair, but it exists. These are the people who tend to set themselves medical diagnosis. According to Velistan, experts believe that researching our symptoms online can cause significant anxiety.

Spending too much time on social media doesn't help at all. Screens can cause sleep disturbances. Don't forget to turn off at the end of the day mobile phone and computer. Research shows that excessive use of technology - especially before bed - can negatively impact our sleep cycles due to the high brightness of our screens. This is especially true for younger people who often need help getting long enough nights.

Video games are great! But what happens if you play them too much? This can give both positive and negative results. There are examples all over the world of gamers who played for too long, literally didn't make it to the credits. Overkill in video games can be a serious problem. As with all pleasant things in this world, everything should be in moderation. Too much a large number of anything from sleep to water can lead to certain negative consequences.

But despite some tragic effects, video games aren't all that bad. First, they deliver incredible pleasure. Second, they can improve just about everything about you, from critical thinking to motor coordination.

Sometimes they can even make you smarter. Therefore, it is necessary to take a closer look at what impact video games can have on a person and what harm they cause to the body.

Regardless of these studies, experts believe that this paradox was a very real phenomenon. Social media has been associated with feelings of loneliness and decreased satisfaction and well-being, which is not really reassuring. With the latest generations of consoles, players have gone from admiration to indifference to salons. This is the main premise of our analysis today, and we will try to explore it. These two branches of games have been relatively close to each other for several years, and even a little too much.

Sit down, take herbal tea, and let's take a look at this videoludica culeo minority report. Understand here that, and especially, the collective subconscious has not yet been dealt a severe blow and that the cliché of the computer geek as being out of control, as lower sides still in effect.

You can die from thrombosis

Long gaming sessions are not unusual. But what if they threaten your life? Yes, then it's still too much. A condition known as deep vein thrombosis can develop if you sit still for a long period of time.

A British gamer died after developing blood clots caused by thrombosis, which was caused by his lifestyle - every day he spent 12 hours in a row on computer games. And a New Zealand gamer was hospitalized with blood clots in his legs after sitting at his console for four days while on vacation.

It should also be said that the concept of upgrading components was a science that only druids had mastered, speaking in the shadows with a screwdriver by hand. It's hard for the average gamer to say they will change their graphic card, order the best one for a good price after reading a few manuals and mount it yourself. Your car, you buy it dearly, and you're eating off your brakes three years later, looking at what consoles and latest released games can now display, but without being able to play.

Your heart may fail

A 32-year-old man from Hong Kong was found dead in a computer club where he stayed for three days in a row. The man entered the club on January 6, 2015, started playing - and was found dead on January 8. The cause of death is heart failure caused by lack of mobility, low temperature and complete exhaustion due to lack of sleep.

Club staff reported that the same man often stayed at the club for three or four days, and other gamers did not pay attention. special attention on what is happening, when the body of an unlucky gamer was taken out into the street.

It's prettier on console!

Including aggravated social aspect that lounge machines and their friendly but limited split-screen took time to integrate, the computer was able to place itself among gamers.

This is not always the case, and the standardization of console components for many. Today, several titles are exclusive to the platform, and developers have learned to treat the computer as a real gaming medium, with a real audience waiting for them on the go.

You can develop "nintendoit"

Even if you take breaks between gaming sessions, repeated use of the controller for hours, days, weeks, months, and years can take its toll. The game usually requires the gamer to repetitively repetitively move their thumbs and fingers, and a 2003 study found that many gamers suffered from repetitive arm strains (a syndrome that was dubbed "nintendoitis").

Consoles eternally plentiful in terms of innovation?

You can hurt your back

A 1999 study looked at back pain in schoolchildren and its relationship to what children enjoy doing, including watching TV and playing on the computer. The report indicated that there was an association between computer games and back pain. These pains were manifested in those children who reported to the researchers that they spend at least two hours a day at the computer.

All this is due to the greater or lesser reactivity of console platforms. Ah, the answer element: I was told in the headset that consoles had become multimedia hubs. This has certainly not escaped you: the next big wave of video-religious innovation will be virtual and will increase. Now we have reached the stage of videohuman stagnation, and it is important for the environment to offer a revolution in size, a way to develop the gameplay of different genres. If we look at different types games, we note that over the past 10 years, very few have really changed.

You can hurt your eyes

It should not surprise you that prolonged staring at a screen, whether it be a TV, computer, smartphone or tablet, does not positive impact to your eyes. There is even such a disease as a syndrome computer vision. It manifests itself in people who spend several hours a day behind computer screens.

Finally, a "revolution" that could attract consoles?

So the new console innovation of this generation will be around virtual reality and mixed reality. Two sectors that have also experienced it for more than three years. Thanks to these peripherals and accessories, the most creative people have been able to create impressive experiences by combining
