How to choose a schoolbag style suitable for primary school students

Primary school students are in the stage of growth and development-all organs and tissues of the body are delicate-especially the bones are not fully mature. The muscles and ligaments around the spine are fragile, and the spine relies on the spine, muscles, ligaments, small joints and intervertebral discs to maintain its shape. In the process of growth and development, it is easy to deform if it is malnourished or influenced by gravity.

knapsack

Backpack is the best choice for primary school students, because it can disperse the weight, reduce the burden on the spine and protect the health of the spine.

Shoulder bag, handbag

Shoulder bags, handbags and tie-rod schoolbags all have the same problem, that is, all the weight is pressed on one side of the body, which makes one side of the spine compressed and the other side pulled, resulting in imbalance. At the same time, the blood circulation of the compression side shoulder is also affected to some extent.

Pull-rod schoolbag

Although the tie-rod schoolbag can reduce the burden on the shoulders, it puts great pressure on the arms and wrists because of the need to drag the schoolbag to walk, which is not conducive to the healthy growth of primary school students.
