1. Scoliosis affects digestion and breathing.
Children in primary schools have soft bones and have not been "stereotyped". Long bone, short bone and flat bone all grow and develop in different degrees. Long-term bad sitting posture makes the spine easily deformed, even slightly displaced, resulting in developmental deformity. Common thoracic kyphosis, thoracic or lumbar scoliosis. Thoracic kyphosis makes the trunk unable to stretch freely, which affects the respiratory and circulatory function; Thoracic scoliosis is often manifested as "razor back", which can seriously affect the development of thoracic cavity. Lumbar scoliosis leads to oppression of digestive system, loss of appetite and malnutrition.
2. Poor sitting posture reduces vision.
Poor sitting posture will lead to poor eyesight of students. Adolescence has strong eye adjustment ability, strong adaptability to close work and study, and it is not easy to get tired when seeing things at close range. However, if students read and write at close range for a long time and don't pay attention to protecting their eyes, the ciliary muscles will be over-stressed, which will lead to fatigue and even spasm, leading to accommodative myopia. Accommodation myopia can be transformed into irreversible true myopia if it is not eliminated in time.
3. Cervical intervertebral disc degeneration occurred prematurely.
Poor sitting posture can cause neck muscle fatigue, neck and shoulder pain, neck muscle spasm and even dizziness; Over time, cervical disc degeneration is bound to occur prematurely in adulthood, leading to cervical spondylosis. In particular, some children love to cross their legs, which will cause continuous load on the neck and back, and the muscles and ligaments of the back will be damaged due to excessive stretching for a long time, thus causing idiopathic low back pain.
Long-term sitting posture is incorrect, which causes coccygeal injury by compressing coccygeal nerve, causing coccygeal pain symptoms, including tenderness points or leg pain near coccyx, including coccyx, levator ani and surrounding soft tissues.
Second, the correct sitting posture
The correct sitting posture should be "sitting like a clock". When sitting, your chest and abdomen should be straight, your hips should fall firmly in the middle or behind the stool, your thighs should be horizontal, your feet should be flat naturally, don't shrug or tilt your head, your head, neck and body should be as straight as possible, and your shoulders should be slightly relaxed backwards. It should be noted that the body should not lean forward too much. When the sole of the foot touches the ground, the calf below the knee should be extended 5-6 cm forward. At the same time, keep your hands close to the upper part of your body and relax. This posture can make the blood flow unobstructed, breathe freely, and the nerves of lower limbs are not oppressed, thus maintaining a balanced, stable and fatigue-free posture.
1. Causes of poor sitting posture
Poor sitting posture is mostly due to habit. Why do so many students sit incorrectly?
Physiologically, hundreds of millions of cells in the human body rely on blood transport to complete their metabolic functions. Sedentary will reduce the amount of oxygen-carrying blood in the body, causing muscle soreness, stiffness and atrophy. Muscle fatigue is not enough to support the weight of the body, but gradually "falls down."
Improper sitting posture is mostly caused by bad habits. Teachers, students and parents don't pay enough attention to it, thinking that as long as the children get good grades, the writing posture doesn't matter, and the habit becomes natural. Although many teachers want to guide students to adjust their sitting posture, their requirements for writing sitting posture are not specific, so it is difficult to implement the guidance training, and students can't operate it. Finally, they can only do nothing. Once people's habits are formed, they become extremely difficult to change.
In addition, the proportion of tables and chairs does not match that of children, or the lighting is dim or reflective, which will make students find it difficult to write. In order to maintain a comfortable sitting position and see more clearly, students have to "bow their heads".
2. There are four elements in a healthy sitting posture:
The concept of healthy sitting posture is comfort, and you can move healthily and freely in a safe sitting posture. This concept includes four elements: stability, support, gap and attitude.
Sitting firmly is the basic condition to control the free, comfortable and effective movement of the body in a sitting position: both feet must be flat on the ground or a solid footstool and must not be suspended. The most comfortable knee curvature is 85 to110, while maintaining the "S-shaped" posture with normal physiological curvature of the back. The curved spine can play a buffering role and better support the weight of the body.
In addition, the head should be at the top of the spine smoothly, and the arms should lie flat on the table naturally, so that supporting the arms can reduce the vertical force from the shoulders. Generally, chairs with backs and handrails are preferred for tables and chairs to support them. In addition, you can also put a mat under the table to put your feet. After studying for a period of time, you can prevent and relieve low back pain by properly adjusting your posture, standing up and exercising your waist, stretching backwards and rotating your waist left and right.
Third, the way to correct the child's sitting posture
Kindergarten is very important.
Because the children's imitation ability is very strong at this time, the teacher's demonstration role is very important. Teachers' manners have a subtle influence on children.
Children in kindergartens have good study habits, because kindergartens have strict norms and good incentive mechanisms. Children's habits are unstable. Once a rule is made an exception, all previous efforts will be in vain, and good habits will never be formed again. In order to cultivate children's good study habits, teachers can appropriately use such strengthening means as praise and criticism, affirmation and negation, reward and punishment. There can be no exceptions when formulating specifications. In order to cultivate good habits, we must persevere until good habits are deeply rooted in children's hearts.
Guidance is more important for younger children. It is not enough just to tell children what to do and what not to do, but also to tell them why to do it and how to do it better. Therefore, school education is an important factor for children to develop good study habits.
For example, when a child is just learning, we correct his sitting posture or tell him how to sit, so that the child can listen and stand upright as required. But imagine that humans started as reptiles and later evolved to walk upright. But walking upright is not as comfortable as crawling, and children will be more comfortable lying on the table than sitting upright. Then, it is not easy to start training children to sit, and children will feel uncomfortable. In this case, on the one hand, we know that the posture that children learn is very important and they should sit well. At the same time, we should also see such a natural attribute of human beings, that is, he will be casual, which is related to the early living conditions of human beings.
In this case, how can we teach children to have a correct posture and a natural posture when learning? I am here to offer some suggestions, hoping to help parents. Parents must know that in the process of cultivating children's good behavior habits, there is a principle that we can't let them suffer. For example, you told him today that he must sit up straight, his shoulders should be flat and his eyes should look straight ahead. When you tell him, he can really do it at once, but after a while, when his attention shifts, his body habitually bends down.
2. Develop good sitting habits.
We must understand a truth: the formation of children's good habits must be repeated many times. This repetition is very meaningful. Some parents think that children should remember it once or twice.
From the perspective of children's behavior types, visual children account for 29%, auditory children account for 34% and kinesthetic children account for 37%. In other words, there are many kinesthetic children, and they may not do well in developing the correct sitting posture. At this time, because he is kinesthetic, he talks too much, and the child may not accept it. In this case, parents or teachers should change their methods: it is best to walk up to him, pat him on the back, give him a hint, and then he sits up straight. This is a kinesthetic child. Because patting is an action and the child is a kinesthetic learner, he likes to be patted. We use language to emphasize that he sits up straight and stands up straight, which is one of many ways.
Post some pictures or tips about correct sitting posture at home. In this way, we will emphasize it from three aspects: vision, kinesthetic and auditory. Parents must be patient when cultivating their children to sit. Let them sit up straight today, tomorrow and the day after tomorrow. After a long time, children will develop the habit of sitting up straight. In this way, in the whole process of cultivating children to form a good habit of sitting up straight, he did not suffer, nor did he abandon his parents, but also developed a habit.
It is a long process to form children's habits. Teachers and parents should show their patience and perseverance to help children develop good habits that are beneficial to their lives.
