Researchers say that overweight schoolbags can harm children's spine. Because students have to carry schoolbags to school every day, in the long run, they will feel unwell, feel tired of learning and affect their academic performance.

In a report published in the journal Gait and Posture, the researchers mentioned that they recorded the movements of children's shoulders, spine and knees with the help of three-dimensional motion capture software, and found that carrying a backpack on both shoulders would increase the curvature of the trunk and put pressure on the cartilage layer between 24 vertebrae, and the backpack strap would also cause discomfort in the back and neck. Among the subjects who used backpacks, 43% had symptoms of back pain.

Suggestions for choosing a schoolbag:

1. The material of the schoolbag should be soft, which can reduce the pressure on the back.

2, it is best to choose a backpack, because the weight of the bag can be evenly distributed on the waist and pelvis, and the bag is fixed at the waist to prevent the bag from shaking and reduce the pressure on the spine and shoulders.

3. The schoolbag has multiple bags, which can prevent all heavy objects from being pressed on the back.

4. The shoulder strap should be wide, which helps to reduce the pressure caused by the schoolbag on the shoulder and can evenly distribute the weight of the schoolbag.

5. The weight in the schoolbag should be 10% to 15% of the weight of the bearer. Being overweight may affect your physical development.
