What Impact Will A Heavy Primary School Backpack For Girls Have On Children

- Oct 22, 2020-

How can I know if my child’s schoolbag is too heavy? The American Academy of Pediatrics (AAP) recommends that the weight of schoolbags carried by elementary and junior high school students should not exceed 10% of their body weight. For example, if a child weighs 30KG, his schoolbag should not exceed 3KG.


If the child has the following situations when carrying the schoolbag, he should consider whether the  primary school backpack for girls is too heavy:

It is very difficult to carry or put down the schoolbag;

Lean forward when carrying a schoolbag;

I always tell you that I have a sore shoulder.


In fact, the weight of schoolbags has become a common phenomenon, and the average child's schoolbag exceeds the weight he can carry.


A  primary school backpack for girls that is too heavy will have a certain impact on the health of the child.

1. Backache

If your child comes home and complains about neck pain and back pain, it may be because the schoolbag is too heavy, pressing on the child's muscles and causing a slight soft tissue contusion.


Especially when the schoolbags are heavy and the students don't carry the schoolbags correctly, the heavy  primary school backpack for girls will drop the pupils back. In order to balance, they will involuntarily lean forward, which may cause compression of the cervical spine and further cause the symptoms of shoulder and neck pain.


A study of 531 Northern California elementary school students showed that overweight schoolbags can cause discomfort to the person carrying them and cause upper back pain.


2. Bent over

In 2008, the Hong Kong Polytechnic University once invited 8 adults to do an experiment. They used a schoolbag that accounted for 15% of their body weight and carried them on their chest and back repeatedly for 20 minutes each time.


The results show that if a schoolbag of this weight is carried on the chest for 20 minutes, the spine will be shortened by 8 mm, and the spine will be shortened by 6 mm if it is carried on the back.


In addition, a study by the University of California also showed that overweight schoolbags can compress the height of the lumbar intervertebral disc, increase the curvature of the lumbar spine, and may cause back pain. In addition, a Spanish study involving 1403 students also showed that students Long-term carrying overweight school bags will increase their risk of spinal diseases.


The schoolbag is too heavy, it will further affect the child's body shape. Because the child is carrying a heavy schoolbag, in order to reduce the load, the child will unconsciously tilt the head, neck and upper back forward, and bend the shoulders inward. If this happens, it may cause a hunched posture.
