Humpback is related to children's calcium deficiency, inferiority, overweight schoolbag, soft mattress, playing electronic products, crossing their legs and kneeling in a W posture. Children will think hunchback is a normal posture, so we should correct this concept first.
The golden age of children's skeletal spine development is 6- 12 years old, so 7 years old is a good correction period. During this period, children's spine is easily corrected, and children are more likely to form good habits.
If the child has the habit of hunchback since childhood, it is easy to form pathological hunchback in adolescence, which will affect the cardiopulmonary function of the chest, such as poor breathing, shoulder and neck chest pain and so on.
Let's talk about children's daily necessities:
Schoolbag Everyone knows that carrying a schoolbag may affect the spine, but how to carry it correctly? According to many studies, if the weight of adults or children exceeds 12.5% (that is, 1/8), the body posture will change, so it is very important to choose the correct schoolbag:
1. The weight of schoolbags (including hand-held articles) shall not exceed 1/8. Some schoolbags are heavy. Even if many ergonomic straps are designed, it is not recommended for children to carry them.
2. You should choose a soft shoulder bag: Try not to drag the bag with a roller, because the child needs to pull the bag with one side, and the posture will still change. Don't let children carry schoolbags on one shoulder. Sometimes high and low shoulders have a lot to do with carrying a schoolbag on one shoulder for a long time.
3. The shoulder strap of the backpack should be wide and soft. The wide version of the shoulder can evenly distribute the pressure on the shoulder, and prevent the child's shoulder muscles from being strained or squeezed.
4. The width of the schoolbag should not exceed the shoulder width, otherwise it will affect the swing of the hand. A schoolbag wider than a child's body will make the child's posture strange. Children will succumb to their posture, adapt to their schoolbags, and make their bodies, hands and feet asymmetrical.
5. The lower edge of the schoolbag must be above the pelvis, and the overall weight should be close to the center of the upper back of the body and close to the waist. If there is an extra belt in the schoolbag, the pressure on the child will be dispersed, which is actually an ideal choice.
Finally, it is recommended to choose a push-pull luggage!

The desk lamp is actually related to the hunchback of the child. Why? Because insufficient or too strong light will affect children's homework, and insufficient light will make children lean forward to carefully examine the questions and write, so it is also important to choose a desk lamp suitable for children:
1. The lighting of the desk lamp should be sufficient:
The desk lamp must have enough illumination, and the illuminated surface must be bright enough to see clearly. Generally, reading indoors, the desktop is about 500Lux (illuminance unit), but in the workspace dominated by computer screen, the illuminance can be lowered.
2. The color temperature should be appropriate:
If you want to choose a bulb or tube with color rendering above 80 and proper color temperature, no matter what kind of bulb or tube you choose, remember to read the label on the package first, and choose a bulb with color rendering (CRI, Ra) above 80, which will make you look more beautiful and comfortable. As for the color of light (color temperature: CCT), a white light source (above 5000K) can be used in the study at home during the day, so that the concentration is higher when reading, and a yellowish low color temperature (3000K) can be selected at night or in the bedroom at home, because low blue light is beneficial to sleep; Generally warm white (4000 K ~ 5000 K) is suitable for various occasions.
3. To prevent glare:
The desk lamp should not have glare or flicker. When the desk is working, it is expected that there will not be too strong light spots in the field of vision. Flashing lights can easily make people dizzy and even cause vomiting, but we should also pay attention to avoid the position of the electric fan below the lamps.
Sofas, mattresses and pillows, bedding and furniture are forbidden to be too soft. You know, humans spend13 of their time in bed, so choosing something moderate in hardness, especially mattresses and pillows, is good for children's bone development.
Mattress is too soft, easy to collapse, not easy to turn over; The child's bones are growing, and more than one third of the day is spent in bed. If the mattress is too soft, the spine will curl or bend for a long time, and normal physiological curvature cannot be maintained. Over time, even humpback will appear, which will seriously affect growth and development.
The mattress is too hard to support all parts of the body well. If it goes on for a long time, it will cause chronic damage to the spine and affect the height, figure and development of internal organs of children.
The child's posture on the sofa is very strange, and parents think nothing of it. Actually, it's not. Although staying on the sofa won't last long, the sofa is the killer of spine health. Many families like to buy lazy sofas, which are soft-packed, which is absolutely inappropriate.
Tables and chairs Of course, it is good to choose artificial chairs that can automatically lift for children, but similar products on the market are seriously at a premium, and parents with hands-on ability can transform them themselves. We often see that the desks and chairs in the classroom are all the same height, but the height of the students is different, which means that some tall children are hunched. Choosing tables and chairs for children doesn't need too much expensive and gimmicks. We can choose according to the height of children:
1. material
The materials for children's desks and chairs are mainly solid wood, plate, stainless steel and plastic, regardless of soft bag backrest and personalized home. The configuration of tables and chairs during children's development is very important. If used improperly, it will lead to hunchback and so on.
2. Specifications and dimensions
The specifications of student desks and chairs are generally 63 cm high and chairs are 32 cm high, which is more suitable for children's body proportion. For most primary school students, this height chair is more comfortable to sit on.
After children go to junior high school, tables and chairs should be raised by 5~ 10 cm. Using inappropriate desks and chairs will make children easily tired, reduce learning efficiency and affect their academic performance. If the chair is too low, you can only stretch your neck. If the chair is too high, you have to bend over. Only when the body, tables and chairs are properly matched can the child's back be straight.

Usually, when choosing a chair, you like to choose a soft armchair, but when choosing a children's desk and chair, the opposite is true. In the normal development stage of children, it is suitable to use furniture such as solid wood or plastic. Soft-packed backrest has great elasticity and fluidity, and it is easy to make the upper end of the spine lean backwards, which can not achieve the purpose of correcting sitting posture or cultivating habits.
4. Handrails
Don't underestimate the armrest of the chair. The armrest of a standard children's desk and chair is at a 90-degree angle. Children have established correct habits since childhood, and their physical development has also been restricted, which has made the spine and waist well developed.
5. Non-slip
Friction plays an infinite role, but what would the children's desks and chairs look like without friction? If the tables and chairs are not slip-proof, they will move nonstop or lack stability. Children may sit askew, or the distance between tables and chairs is too large, which affects their sitting posture and is not good for their development.
6. Environmental protection performance of tables and chairs
Whether the materials are environmentally friendly or not depends on the monitoring report. The main factor to measure whether the material is environmentally friendly is the formaldehyde emission of the material. Need to smell whether the material has obvious pungent smell, if not, it can basically be judged that the material is environmentally friendly. There is also the heavy metal content of tables and chairs. Generally, the brighter the color, the higher the lead content.
If the economic conditions at home are good, buying solid wood materials will definitely protect the environment. (Of course, solid wood is not necessarily environmentally friendly, which is related to the production process. The material itself must be environmentally friendly. If environmentally unfriendly adhesives or coatings are used in the production of tables, it may lead to environmental protection. ).
Matters needing attention in purchasing children's desks and chairs
● adjustability: the height of the chair and the depth of the seat cushion can be adjusted to match the growth of children, so as to ensure that children can fill the seat cushion and have a chair back to support their backs.
● Stability: the center of gravity of the chair should be low and the weight should be sufficient, so that even if the child stands on the chair, it is not easy to fall over.
● Safety; The material of the chair wheel should not be easily broken, even if the chair wheel is damaged, there will be no sharp gap to avoid stabbing children. At the same time, the chair seat does not rotate and the chair wheels are locked, which can avoid the displacement of the chair caused by tampering when reading or writing, and help to maintain a correct sitting posture.
● Health; The curved surface design of the chair back can conform to the curvature of the human spinal cord, and only a perfect fit can provide more support. Children with insufficient legs should be supported by foot pads to avoid being raised at the knee socket.
● Precautions in lighting: The light of the desk lamp can be spread all over the desktop, and the three elements of brightness (illuminance), glare (brightness) and light color (color temperature) create an environment with clear sight, eye protection and suitability for work and study. It is suggested to choose high color rendering (Ra & gt80), that is, the color of the article is close to the natural primary color, and the desk illumination should reach at least 300Lux, which is more in line with the needs of students.
What is the correct sitting posture of children?
1. Sit up straight: Do not lean forward or backward excessively, do not hunch, shrug or skew. Fill the chair with your ass and make your body at 90-95 degrees with your thighs. If necessary, you can take a backrest cushion to help the child sit well.
2. Adjust the seat height: the seat height should be adjustable. Adjust the seat height so that the elbows are the same height as the desktop, or only slightly lower than the table by 5 cm. After sitting down, it is best to keep your body about a fist away from the table. Hands on the table, elbows can naturally bend to 100- 105 degrees, which is a good desktop height.
3. Make sure your feet can be comfortably flat on the ground: check that your child's thighs and calves can form an angle of 90~ 105 degrees, and your feet can be comfortably flat on the ground, so that you can feel stable when sitting and your feet are not so sour. If you can't put your feet comfortably on the ground, don't go back and lower the height of the chair, because the height of the chair should match the height of the table. At this time, you can buy a pedal to make up for the gap.
4. Make good use of reading racks: Children usually need to read books, and they should prepare a reading rack to avoid neck muscle fatigue caused by bowing their heads for a long time.
The child's self-discipline has not been established, and his hunchback is ugly and unnoticed. I just feel comfortable. If no one reminds me, then I won't notice, and my parents can't stay with me at any time to remind me:

It is very useful for parents to remind their children to keep the correct posture at any time, which can awaken their body consciousness, that is, proprioception.
However, some parents said, "I can't always be with my children." Even if you walk with your child, you can't observe the posture of your child in real time!
If you can always know whether your posture is correct, your body will no longer relax! If only someone/something could always remind me whether my posture is correct? In today's intelligent world, this idea not only exists in the mind, but has become a real mass production equipment. The "Little Companion Wanderer" is a similar intelligent reminding device, which can monitor your posture changes in real time and remind you when the amplitude exceeds 5, just like an old friend patting you on the back.
A high-precision gravity sensing chip embedded in it will make a slight vibration when you feel your upper body relaxed. It can tell you when to lean in an unhealthy direction, so that you can keep the correct posture at any time. It can be said that it is a combination of mirror and "mom's reminder". What's important is that mom always doesn't pay attention to your gap, and you will never check whether your posture is correct with a mirror, but the "Little Partner Posture Instrument" can be used only once charged.
Finally, give your child calcium supplements.
The data showed that the top three foods with calcium content were shrimp skin 99 1mg/ 100g, black sesame 780mg/ 100g and dried bean curd 308mg/ 100g. Among green vegetables, broccoli has the highest calcium content. ? 1-3-year-old children can get 604 mg of calcium by taking 50 mg of rice, 480 mg of milk and others from eggs, meat and vegetables every day. In addition, children do more weight-bearing exercises, such as running, skipping rope and playing ball, which is very helpful for bone hardness.
Finally, you can accompany your child to do some exercises to improve hunchback at home.
Parents can choose one or two to do it with their children, which is not only suitable for children, but also beneficial to adults, and can also promote parent-child relationship. Why not?
