What are the effects of long term poor sitting posture on the body?

It will cause pain in the neck, shoulders, lower back and other parts, and in the long run, your joints will be stiff, so you should maintain a good sitting posture.

Poor sitting posture will damage our body, cervical spine, spine, and lumbar spine, and in the long run, it will be easy to get lumbar disc herniation, spine bending, and hunchback.

Long-term poor sitting posture can easily cause some bone hyperplasia or muscle soreness. In addition, it may cause diseases such as lumbar muscle strain, so be sure to pay attention to your sitting posture. In addition, it is easy to induce hunchback or poor limb shape in terms of body shape.

<>Hazard 1Cervical spondylosis: due to poor sitting posture, especially when you bow your head for a long time, work at the desk, look at your mobile phone, and look at the computer, it is easy to appearDegenerative changes of the cervical spine, the physiological curvature of the cervical spine will straighten or disappear, and in severe cases, it will reverse the arch。This causes degenerative changes in the ligaments and joints around the cervical spineSevere disc herniation or cervical spine instability, compressing surrounding blood vessels or nerves, with a range of symptoms.

Hazard 2Scoliosis: Children and adolescents are in the period of physiological developmentThe joints and ligaments of the spine are not fully formed or are in a relatively weak period, due to poor sitting posture for a long time, can causeDevelopmental abnormalities, resulting in scoliosis of the spine.

Hazard 3Low back muscle strain: caused by chronic fatigue, poor sitting posture, etcLong-term high-strength, high-tension state of muscles, causedLocalized ischemia, injury, with severe changes, causing lumbar muscle strain.

Hazard 4Abnormal vision: If you do not see things in a normal position, you may have myopia or abnormal conditions such as refractive error.

Hazard 5,Migraines are present. Some people have the habit of leaning in their chair and looking at the screen with their eyes squinted when working in front of the computer, which can lead to:The muscles of the cervical spine are overly strained, which reduces the blood supply to the cerebral cortex, so it's easy to get migraines.

Hazard 6Elephant legs appear. If the chair is too high or too low, and when sittingThe knee cannot be bent at a right angle, it will lead toPuffiness in both legs, thus forming elephant legs.

How can we prevent the dangers of poor sitting posture?

1. Correct sitting posture

The body is slightly leaned back, and the neck is supported to ensure that the neck releases its own pressure on the support, which can avoid neck fatigue.

The arms hang down naturally, relaxing the shoulder muscles; The arm is supported to reduce fatigue due to the straining of the arm to maintain its position.

Adjust the height of the desk so that your hands are parallel to the keyboard.

Keep your eyes straight ahead and your gaze parallel to the top of your computer screen (or the top third of the display).

The elbow is ideally bent at a right angle.

The knees are positioned slightly below the hips so that the thighs are parallel to the ground and the calves are perpendicular to the ground.

Keep your feet on the ground so that your ankles are naturally at right angles.

2. Avoid sitting for long periods of time

Work for 40 minutes and rest for about 5-10 minutes, stretch your muscles and bones, activate your tense nerves, and look into the distance to adjust your astringent eyes, which is also helpful for work effectiveness.

3. Exercise more

After work, you can run and exercise, which can not only relieve the fatigue of the day, but also relax the muscles.

1 5 Erlang's legs are sick.

Long-term continuous sitting work, especially stilt leg work, will cause continuous load on the neck and back, so that the back muscles and ligaments will be damaged by excessive stretching for a long time, thus causing unexplained low back pain, but as long as you maintain a good sitting posture, after a period of time, it will return to normal and there will be no problems.

In addition, sitting on Erlang's legs for a long time, because the legs squeeze each other, will also hinder the blood circulation in the legs, and over time, it will cause varicose veins in the legs, and in severe cases, it will cause poor blood return in the legs, bruised tendons, ulcers, phlebitis, bleeding and other diseases.

2 5 In your work, you only need to do the following two things to achieve the purpose of preventing neck and back pain: one is to maintain a good sitting posture, and the other is to carry out correct chair movements.

Correct chair movements: First, don't sit in one position for a long time, but constantly change in 2-3 safe sitting positions. Secondly, when bending down to pick up objects on the chair, you should first move your hips forward to the edge of the chair, move one foot forward, prop one hand on the table, and then bend over.

Third, when you turn around to pick up something, your whole body should rotate together. Fourth, when playing **, do not use your head and shoulders to clamp the microphone, but should support the elbow of the upper limb on the side of the microphone on the tabletop to keep the head and neck in a neutral and relaxed position.

3 5 Comfortable sitting posture is not necessarily good.

It's not that a sitting position that you feel comfortable in is a good sitting position. The correct sitting posture should be with the upper body straight, the abdomen tucked, the lower jaw slightly tucked, and the lower limbs together. If possible, raise the knee slightly above the hip.

If you sit in a chair with a backrest, you should try to keep your back close to the back of the chair on the basis of the above posture, so that the muscles of the lumbosacral region will not get tired. After sitting for a long time, you should move to relax the muscles of your lower limbs. In addition, patients with lumbar disc herniation should not sit on a low stool lower than 20cm, and try to sit on a chair with a backrest, so that they can bear part of the weight of the body and reduce the chance of low back strain.

4 5 Poor sitting posture causes cervical spondylosis.

The root cause of cervical spondylosis is the degeneration of the cervical intervertebral disc, which loosens the intervertebral disc and compresses the nerve roots, spinal cord or vertebral arteries. Long-term poor sitting posture or staying in front of the computer for a long time is most likely to cause fatigue of the neck muscles, causing neck and shoulder pain, neck muscle spasms, and even dizziness; Over time, cervical disc degeneration is bound to occur prematurely in adulthood, leading to cervical spondylosis.

For the correct sitting posture operated by the computer, please make sure that the entire ball of your foot is on the ground when sitting. Use an adjustable work table, chair, or floor pad that keeps your feet on the ground. If using a foot pad, make sure the foot pad is wide enough for your legs to move freely around the work area.

Stretch your legs often and change the posture of your legs. Stand up often, walk a little away from the workbench and change the position of your legs frequently to relax the whole person. Be careful not to place boxes or other items under the table, as this will limit legroom.

Sitting posture is incorrect, there are um, there are many undesirable effects, such as the growth of your bones and the lumbar disc of your waist, which have a great impact, so the correct organization helps a person's growth and governorship, and then the sitting posture of this thing, in the long run, if the sitting posture is incorrect, the harm will be um, the bone deformation is prominent, the depression and the like can be used with sitting orthosis or adjust the sitting posture yourself to try it.

Sitting incorrectly for a long time can cause many diseases. For example, children will cause myopia during learning, and will cause lumbar spine curvature and hunchback. Adults who sit incorrectly for a long time can cause diseases such as herniated lumbar discs.

It may cause curvature of the spine and herniated disc in the lumbar spine.

Sitting incorrectly for a long time can damage the bones of the body. Scoliosis also has hazards such as lumbar disc herniation.

Poor sitting posture can cause great harm to the body, because many people will have lumbar pain or cervical spine pain in the process. If this sitting posture has not been corrected, it is easy for the human body to suffer from lumbar spondylosis or cervical spondylosis. For some office workers, sitting for a very long time each day is very long.

If you don't pay attention to your sitting posture during this process, it can also lead to lumbar disc damage. <>

For many office workers, they do it for a long time every day, and some people are very inattentive to their sitting posture in the process. If you don't pay attention to your sitting posture, you will find that many people will have lumbar spine pain and cervical spine pain. If this sitting posture is not corrected, it will also lead to lumbar spondylosis or cervical spondylosis.

Once these diseases appear, you will find that your body is particularly painful, and it will also affect your life. If this happens, you should adjust your sitting posture and go to the hospital for a check-up. <>

There are also some people who may have some other diseases during this process, and some people do not pay attention to their sitting posture, and their vision will change very much after a long time. Because in this process, many people will feel that their eyesight is getting worse and worse, and even have symptoms of cataract and glaucoma. Sitting for long periods of time can have a particularly significant impact on the body, and some people develop blood clots in the process.

So sitting is very important, but in the process, you can also stand up and walk. <>

Many people may not have to sit down soon because of the needs of work, but they can also stand up and relax occasionally at this time. Because sitting for a long time can cause a lot of pressure on the body, and it can also cause damage to the nervous system. When you feel very tired, you can also stand up and relax.

During this process, you can also choose to do some exercises to relieve the tiredness of the body. However, don't push too hard during exercise, as too much force may also cause muscle damage.

People who have been sitting poorly for a long time may experience symptoms of a herniated disc in their lumbar spine, scoliosis of their spine, and may even cause their pelvis to tilt. In addition, poor sitting posture can also aggravate the degree of myopia.

It can affect nerves, can cause muscle strain, may cause shoulder pain, can lead to a herniated disc in the lower back, and can also cause chest sagging.

It can easily lead to anterior pelvic tilt, leading to diseases of the cervical spine and lumbar spine, which can easily lead to herniated lumbar discs, resulting in bone deformation.

It is likely to cause cerebrovascular disease due to irregular heartbeat. Obesity. Hyperlipidemia and hypertension can also cause the pelvis to tilt anteriorly.

1. Frozen shoulder: long-term incorrect sitting posture or long-term heavy physical labor may cause frozen shoulder. If you sit incorrectly for a long time, it can cause the scapula to tilt to one side, causing uneven stress on the normal acromion and humerus, resulting in frozen shoulder.

It can usually be carried out with drugs under the guidance of a doctor**, such as ibuprofen sustained-release Chongdou Zhao capsules, Nimesulide dispersible tablets, etc.;

2. Cervical spondylosis: long-term incorrect sitting posture or cold, etc., may induce cervical spondylosis, if you maintain an incorrect sitting posture for a long time, it will lead to excessive pressure on the neck, and the spine can not be stretched smoothly, which will gradually deform the spine, and then develop into cervical spondylosis.

3. Lumbar intervertebral disc herniation: If you maintain an incorrect sitting posture for a long time, resulting in uneven force on the lumbar intervertebral disc, which may cause lumbar muscle soreness and local muscle strength, and then lead to lumbar intervertebral disc herniation, patients can take diclofenac sodium sustained-release tablets, aminophen tramadol tablets and other drugs according to the doctor's instructions**.

4. Abnormal vision: If you do not see things in a normal position, you may have myopia or refractive error and other abnormalities.

Poor sitting posture, lack of sleep, irregular work and rest, lack of exercise, and disturbed thoughts can all increase fatigue. Fatigue includes brain fatigue and physical fatigue, brain fatigue is affected by various pressures in life, the fatigue of trivial things in life will continue to accumulate in the brain, once the brain feels tired, it will be very cautious to convey the information of "exhaustion" to the body, so that it will feel fatigued.

Therefore, the fatigue of the brain also signals through the body that it feels "tired". In addition to physical fatigue caused by a lot of physical exertion, there is another bad habit that cannot be ignored, that is, poor posture.

Poor sitting posture will greatly increase the force on the lumbar spine and cervical spine, unconsciously increase the burden on the muscles, and eventually lead to muscle strain, making your body tired and tired the more you sit.

What are the dangers of poor sitting posture?

It may cause muscle strain and herniated discs.

In addition to the lumbar spine, poor sitting posture also causes a lot of stress and burden on the cervical spine and its surrounding muscles. When the fibrous ring of the intervertebral disc is slowly damaged and eventually ruptures, the nucleus pulposus tissue of the spine will gradually protrude from the rupture, which may compress the surrounding nerves and spinal cord, and over time, it will lead to serious symptoms such as muscle strain and herniated disc.

Leads to obesity. Sitting in the wrong posture for a long time will make the muscles of the buttocks, waist and neck stiff, fat accumulation, reduce the body's metabolic efficiency, further aggravate the fat accumulation in these parts, gradually become obese, and easily form a pear-shaped body.

There are many dangers associated with poor sitting posture. Saggy breasts. Leaning forward, hunchbacking, the whole person is nesting in front of the computer.

The body staring at the computer will always unconsciously lean forward, and the chest will press against the edge of the table and gradually squeeze to the sides, causing deformation and sagging. Working at a desk is most likely to result in a hunched back and bent shoulders. This sitting position will make the chest loose and weak, without the strength to support, the chest will not be able to resist gravity!

Correct sitting posture, remembering the principle of "one punch from the chest to the table". If you keep forgetting, bring an exaggerated long necklace or cut half of a tennis ball and snap it on the table facing your chest, which can be a good reminder. You can also try using the mouse with your other hand every two weeks, which can also effectively prevent your body from leaning to one side.

Migraine, cheek against the table, squinting at the screen. Leaning against your desktop and staring at a screen? Put the handset between your shoulder and your head**?

These postures can make the muscles near the cervical spine too tense and reduce blood flow in the cerebral cortex**. In addition, a computer screen that is too high or too low can make you unconsciously shrug your shoulders and hunch, deform your cervical spine, and easily lead to migraines. To sit properly, first check the position of your computer.

The middle part of the monitor should be placed just on the chin; If you can, it's best to use a megaphone or headphones to connect **, and resolutely avoid the wrong sitting posture of using the earpiece to connect **. Girls who need to type constantly every day can put a small tip prominently on the edge of the keyboard, such as: "Don't shrug your shoulders!"

Tick, no! ”。

The table top is too high. Shrug your shoulders to operate the keyboard and mouse. Female wrists are thinner, and the nerves in the middle of the wrist are under greater pressure, so the attack rate of mouse hands is more than three times that of women.

The posture of pressing the palms down and supporting the wrist on the table puts all the weight on the nerves, muscles, and blood vessels of the wrist, and the dorsiflexion of the wrist joint is almost close to the maximum. If this condition persists for a long time, the blood circulation of the hands will be affected, and the hands of the rats will naturally find the door! For proper sitting, the higher the position of the keyboard and mouse, the greater the dorsiflexion of the wrist joint.

We can put them a little lower depending on our situation. The height of the mouse elbow is the height of the mouse when the mouse elbow is placed; At the same time, exercise your wrists, clenched fists, and fingers every half hour.
