Schoolbag is a necessary learning tool for children. Many parents often only consider the appearance and durability when purchasing schoolbags, but ignore the health care function. In fact, children's schoolbags have a great influence on their physical development, such as improper selection, easy injury to the spine and back formation. Parents should pay more attention to the health problems caused by schoolbags. So, how should we choose the right schoolbag?
Choose a schoolbag and look at three "straps": shoulder strap, belt and chest strap.
Because most children's schoolbags are heavy enough, it is very easy to block blood flow, which will lead to muscle injuries, especially shoulders. Therefore, it is generally suggested that the shoulder width should be wider, which will help to reduce the pressure of the schoolbag on the shoulder and evenly distribute the weight of the schoolbag, while the shoulder strap with cushion can reduce the strain of the schoolbag on the trapezius muscle.
In addition to wide shoulder straps, children's schoolbags are best equipped with belts and chest straps. In the past, schoolbags generally didn't have belts and chest straps, only some backpacks had them. But in fact, it is very important to add these two belts. Using the belt and chest strap can make the schoolbag closer to the back, the weight of the schoolbag can be evenly unloaded on the waist and pelvis, and the schoolbag can be fixed on the back to prevent the schoolbag from shaking and reduce the pressure on the spine and shoulders.
A healthy schoolbag should be light and tasteless.
The material of children's schoolbags should be light, because children have to bring a lot of books and articles back to school every day, so in order to avoid the increase of children's load, the schoolbags should try to choose light-fitting materials. It is generally recommended that the content of children's books should not exceed 15% of their own weight.
Smell the bag when you buy it. If there is a pungent smell, it is likely that the formaldehyde content in the schoolbag exceeds the standard, which poses a greater threat to children's health.
A healthy schoolbag, it is best to protect the spine and prevent the back.
Because the child's spine is soft, it is easy to deform after long-term oppression. If the schoolbag is improperly designed or too heavy, it will easily lead to the child's back. When purchasing schoolbags, you can consider choosing schoolbags with spine protection function, such as schoolbags with no pressure on the hollow back, which can reduce the chance of schoolbags hitting the spine. The hollow back design can prevent schoolbags from sticking to the back and prevent children from "sweating". It should be pointed out that schoolbags with spine protection function are often expensive.
Children who carry unreasonable schoolbags are easy to carry. Parents should choose a schoolbag designed with the center of gravity inner plate. The center of gravity inner plate is convenient for placing heavy books, so that the center of gravity is close to the back, which can keep the back straight and reduce the chance of the back.
Scientifically remove health risks with schoolbags.
Even if you buy a healthy schoolbag, you should pay attention to the rational use, otherwise you will not achieve the health care effect, and even lead to new security risks. We should do the following three things:
1. Children should carry their schoolbags as required, fasten all kinds of buttons and walk in a reasonable posture.
2. Educate children not to put anything except books and stationery in their schoolbags, especially food and toys. On the one hand, this will help to "reduce the burden", on the other hand, it can also avoid the spread of diseases.
3. The baby's schoolbag should be cleaned regularly, so that the child and parents can clean it together.
