Schoolbags Promote Burden Reduction

"Reducing the burden" of children's schoolbags has always been a topic of public concern. Do you know the most suitable weight for schoolbags? An article in the American "Life" magazine pointed out that the weight of the backpack should not exceed 10% of the weight of the backpacker.

A study of 9th graders by the American Physical Therapy Association shows that backpacking too heavy and the wrong way can lead to back injuries and muscle fatigue in teens.

Researcher Mary Ann Wilmarth said children with heavy backpacks can cause kyphosis, scoliosis, forward leaning or twisting.

At the same time, muscles can become fatigued from extreme tension, leaving the neck, shoulders and back vulnerable to injury. If the weight of the schoolbag exceeds 10%-15% of the backpacker's weight, the damage to the body will increase exponentially. Therefore, she recommends keeping the pack weight under 10% of the packer's body weight.

The American Physical Therapy Association recommends that children use backpacks on both shoulders as much as possible. Experts say that the double-shoulder method can spread the weight of the pack, thereby reducing the possibility of distortion.

In addition, trolley schoolbags are a good choice for younger students; because senior students in the United States often need to go upstairs and downstairs to change classrooms, while junior students do not have these troubles.

In addition, it is also important to place the contents of the bag properly: the heaviest items are placed close to the back.
