Whenever the school season arrives, it is a headache for parents to buy stationery for their children. Among all stationery, a good-looking and practical school bag is essential and the most important.

When buying schoolbags, many parents often only consider the style, color, price and whether their children like it, but ignore the design and material of the schoolbag itself, which is a very bad shopping habit. If the design of the schoolbag is unreasonable and the size is not suitable, it is likely to affect the physical development and health of the child.

Some schoolbags that look very bright and good-looking may contain chemicals that are harmful to children's health. Therefore, for the health, safety and comfort of children, parents must grasp the details when choosing school bags for their children. Let's take a look at some key points for choosing school bags for students.

1. Try to choose a backpack

When choosing school bags for children, we try to choose backpacks, single shoulder bags and trolley bags are not recommended. The weight of the shoulder bag is pressed on one side, which puts pressure on one side of the spine, causing the muscles on both sides to be tense and unbalanced, which may lead to sloping shoulders and abnormal curvature of the spine. The trolley bag is not conducive to the health of the spine, and it is also prone to accidents.

2. The back and bottom of the bag should be hard

Some schoolbags with a soft back panel are easily deformed due to the weight when loading items, resulting in frequent changes in the center of gravity of the schoolbag, affecting the stability of the child's body center of gravity. A good-quality school bag needs to have a hard backboard and bottom plate to ensure that it is not easily deformed when loading heavy objects, and does not cause unnecessary damage to the spine.

3. The side of the schoolbag should be thin enough

The schoolbag you choose for your child should not be too thick, it needs to be relatively thin. The thin schoolbag limits the range of the items in the schoolbag being shaken back and forth, which can make the position of the items in the schoolbag relatively fixed, maintain the center of gravity in a relatively stable state, and reduce the burden on the spine caused by frequent changes in the center of gravity.

4. Have a reflective strip design

Another very important detail of a child's schoolbag is the reflective strips. The front, sides and shoulder straps of the schoolbag should be equipped with reflective strips. The reflective material on the schoolbag makes it easier for students walking on the road to be identified, and acts as a warning to passing vehicles.

5. Choose safe materials

The material of children's schoolbags must be safe and odor-free. It is recommended that you buy qualified products produced by regular manufacturers. If the schoolbag has a pungent smell, it may be an unqualified product. Long-term exposure to such products will affect the health of children.

After choosing a suitable school bag for the child, how the child uses it will also affect the use effect of the school bag. The wrong way of using it will lead to the child's corresponding chest and hunchback state. Let's take a look at how to place the items in the school bag.

1. Front center of gravity inside the bag

When placing books in the schoolbag, try to place the heavy objects on the side close to the body, so that the center of gravity of the schoolbag is as close to the center of gravity of the body as possible. If the center of gravity is more backward, there will be a force that pulls the torso back, resulting in a corresponding state of chest and hunchback.

2. The books should be placed with the same weight on both sides

When placing items in the bag, pay attention to keeping the weight on the left and right sides basically balanced. If the left and right sides are light and heavy, it is easy to cause unbalanced force on the left and right shoulders, and eventually let the child form high and low shoulders.

3. Fix the item

When placing books and stationery in the schoolbag, try to keep the contents as stable as possible without shaking them. The purpose of this is to keep the center of gravity stable, reduce the change of the center of gravity of the schoolbag during walking activities, and avoid the resulting spinal fatigue.
